description","speaker":null,"is_sponsor":0},{"start_s":120.719,"end_s":127.52,"text":"so i noticed that you designed a water block is there a reason that other than","speaker":null,"is_sponsor":0},{"start_s":125.36,"end_s":132.48,"text":"flexing the new workshop here that we didn't just use a standard water block","speaker":null,"is_sponsor":0},{"start_s":129.92,"end_s":137.599,"text":"and put it on top of the tech yeah so a water block like this even","speaker":null,"is_sponsor":0},{"start_s":134.879,"end_s":142.72,"text":"though it looks size wise like it's it should be a pretty good yeah cpus only","speaker":null,"is_sponsor":0},{"start_s":141.12,"end_s":147.44,"text":"on the die they really create a lot of heat so water blocks","speaker":null,"is_sponsor":0},{"start_s":144.959,"end_s":151.68,"text":"only really cool the center right so the actual fin structure of a","speaker":null,"is_sponsor":0},{"start_s":149.599,"end_s":157.84,"text":"typical cpu water block is only about this big so what happens then to our","speaker":null,"is_sponsor":0},{"start_s":154.72,"end_s":159.2,"text":"tech if we only cool the center of it","speaker":null,"is_sponsor":0},{"start_s":157.84,"end_s":164.64,"text":"it just won't be as efficient and it's going to get really hot around the edges","speaker":null,"is_sponsor":0},{"start_s":161.76,"end_s":168.72,"text":"so we had to design this fairly massive","speaker":null,"is_sponsor":0},{"start_s":166.8,"end_s":172.8,"text":"block like if you it's hard to get a sense of the scale when we're looking at","speaker":null,"is_sponsor":0},{"start_s":170.4,"end_s":176.08,"text":"it like this so how big is it the scale like these mounting holes right here","speaker":null,"is_sponsor":0},{"start_s":174.72,"end_s":180.8,"text":"yeah are the same but but the actual size we're actually going","speaker":null,"is_sponsor":0},{"start_s":178.879,"end_s":185.599,"text":"almost right to it so it's quite a bit larger yeah it's like","speaker":null,"is_sponsor":0},{"start_s":182.319,"end_s":187.28,"text":"about this big so we have a 65","speaker":null,"is_sponsor":0},{"start_s":185.599,"end_s":191.76,"text":"millimeter inner channel thing which is just a bit","speaker":null,"is_sponsor":0},{"start_s":189.12,"end_s":195.84,"text":"larger than the diameter of this so it should work pretty well","speaker":null,"is_sponsor":0},{"start_s":193.92,"end_s":199.36,"text":"unless it doesn't another reason we had to design our own block was that it","speaker":null,"is_sponsor":0},{"start_s":197.28,"end_s":204.48,"text":"needs to have some special functionality like okay it's great in theory to say you","speaker":null,"is_sponsor":0},{"start_s":202.319,"end_s":208.0,"text":"stick this on top to cool the hot side and then the cpu gets cooled by the cold","speaker":null,"is_sponsor":0},{"start_s":206.4,"end_s":213.519,"text":"side but what keeps this in place","speaker":null,"is_sponsor":0},{"start_s":209.92,"end_s":215.28,"text":"not just in place but clamped against","speaker":null,"is_sponsor":0},{"start_s":213.519,"end_s":219.599,"text":"the cooling element so that it gets optimal thermal transfer well that's","speaker":null,"is_sponsor":0},{"start_s":217.44,"end_s":223.44,"text":"where this type of sandwich design comes in so you can see we've got our cooling","speaker":null,"is_sponsor":0},{"start_s":221.519,"end_s":227.12,"text":"element here on the top and then you can actually see this very nice attention to","speaker":null,"is_sponsor":0},{"start_s":225.44,"end_s":230.959,"text":"detail by the way thank you i like this with the leads going in and everything","speaker":null,"is_sponsor":0},{"start_s":228.56,"end_s":235.44,"text":"you can see the peltier element is sandwiched in between then","speaker":null,"is_sponsor":0},{"start_s":233.28,"end_s":240.4,"text":"we've got these right here these bolt throughs are going to hold","speaker":null,"is_sponsor":0},{"start_s":238.159,"end_s":246.239,"text":"these pieces together really really tightly and bind them to this","speaker":null,"is_sponsor":0},{"start_s":243.84,"end_s":249.92,"text":"this cold plate at the bottom so","speaker":null,"is_sponsor":0},{"start_s":247.04,"end_s":254.159,"text":"for much the same reason as we can't just attach a tiny cooling element to","speaker":null,"is_sponsor":0},{"start_s":252.4,"end_s":258.639,"text":"the top of the hot side of the peltier and expect optimal efficiency we can't","speaker":null,"is_sponsor":0},{"start_s":256.4,"end_s":263.28,"text":"take the cold side of the peltier and put that against a tiny little cpu and","speaker":null,"is_sponsor":0},{"start_s":261.44,"end_s":267.44,"text":"hope that we're getting the most cooling out of it so we need to have something","speaker":null,"is_sponsor":0},{"start_s":265.36,"end_s":271.52,"text":"to spread the cooling and that's going to be another","speaker":null,"is_sponsor":0},{"start_s":268.96,"end_s":276.24,"text":"copper plate on the bottom that is also sandwiched around it","speaker":null,"is_sponsor":0},{"start_s":273.6,"end_s":280.24,"text":"yeah so another problem that we have is that if you just put this on full","speaker":null,"is_sponsor":0},{"start_s":278.24,"end_s":284.96,"text":"bore like if you just attach it to a power supply sure it's going to cool","speaker":null,"is_sponsor":0},{"start_s":282.72,"end_s":289.6,"text":"down really really fast and really cold yeah so we could end up","speaker":null,"is_sponsor":0},{"start_s":286.96,"end_s":294.16,"text":"with condensation um i mean really condensation yeah condensation lots of","speaker":null,"is_sponsor":0},{"start_s":291.52,"end_s":299.44,"text":"water around your cpu not a great time so that's why we have this guy right","speaker":null,"is_sponsor":0},{"start_s":296.08,"end_s":301.68,"text":"here it's a pid controller and do you","speaker":null,"is_sponsor":0},{"start_s":299.44,"end_s":305.68,"text":"know what pid is actually i don't know what it stands for um proportional","speaker":null,"is_sponsor":0},{"start_s":303.68,"end_s":311.759,"text":"integral and derivative okay so in a nutshell this is like an on","speaker":null,"is_sponsor":0},{"start_s":309.28,"end_s":315.6,"text":"off switch temperature goes in and it says yes that is okay or no that is not","speaker":null,"is_sponsor":0},{"start_s":314.72,"end_s":322.8,"text":"okay and if the temperature is okay then it","speaker":null,"is_sponsor":0},{"start_s":319.84,"end_s":326.32,"text":"ah sends a signal to this guy and says don't turn on the peltier and if the","speaker":null,"is_sponsor":0},{"start_s":324.479,"end_s":329.919,"text":"temperature is not okay it's too high it's higher than what we want then it'll","speaker":null,"is_sponsor":0},{"start_s":327.68,"end_s":334.639,"text":"say hey he'll kick on and this will turn on our block yeah so","speaker":null,"is_sponsor":0},{"start_s":332.88,"end_s":338.56,"text":"that's all well and good although it's a bit sketchy to just have","speaker":null,"is_sponsor":0},{"start_s":336.479,"end_s":341.6,"text":"all of that electronic stuff put on the table","speaker":null,"is_sponsor":0},{"start_s":339.6,"end_s":346.24,"text":"yeah so all that's going in this nice little box right here fun which you","speaker":null,"is_sponsor":0},{"start_s":344.32,"end_s":350.479,"text":"might have noticed this doesn't quite fit so we can either","speaker":null,"is_sponsor":0},{"start_s":348.32,"end_s":355.039,"text":"cut a hole in the top and have a big old fan or we can cut a slot and have it","speaker":null,"is_sponsor":0},{"start_s":353.039,"end_s":360.24,"text":"just sticking out the side i'm a fan of that one because it's easier","speaker":null,"is_sponsor":0},{"start_s":357.28,"end_s":362.8,"text":"okay sticking out the side cool you might be looking at this rather","speaker":null,"is_sponsor":0},{"start_s":361.36,"end_s":367.44,"text":"primitive block and thinking there's no way that's going to cool a 545w peltier","speaker":null,"is_sponsor":0},{"start_s":365.68,"end_s":371.759,"text":"so i'm going to prove it should be fine using solidworks flow simulation for the","speaker":null,"is_sponsor":0},{"start_s":369.52,"end_s":375.68,"text":"simulation we've got a 545 watt heat source some thermal paste and a fluid","speaker":null,"is_sponsor":0},{"start_s":373.6,"end_s":378.16,"text":"input with a flow rate of a d5 pump the only real assumption that i've made is","speaker":null,"is_sponsor":0},{"start_s":377.039,"end_s":381.919,"text":"that the water would reach a steady state temperature of about 42 degrees","speaker":null,"is_sponsor":0},{"start_s":380.24,"end_s":384.88,"text":"which seems reasonable enough given the huge radiator that we're using after","speaker":null,"is_sponsor":0},{"start_s":383.6,"end_s":389.28,"text":"running the simulation we can see that the flow does a reasonably good job of going through the fins and the water","speaker":null,"is_sponsor":0},{"start_s":387.68,"end_s":394.319,"text":"resistant temperature by about two degrees while making its way from one side to the other the temperature of the","speaker":null,"is_sponsor":0},{"start_s":392.24,"end_s":398.24,"text":"peltier rises quickly at first but it hits steady state at around 54 degrees","speaker":null,"is_sponsor":0},{"start_s":396.24,"end_s":401.36,"text":"after a minute or two which seems slightly low to me but basically","speaker":null,"is_sponsor":0},{"start_s":399.6,"end_s":404.8,"text":"confirms that if we have a problem it's probably not due to bad cooling","speaker":null,"is_sponsor":0},{"start_s":407.68,"end_s":413.12,"text":"oh man it's gonna be like the most full send video we've done in a while","speaker":null,"is_sponsor":0},{"start_s":411.52,"end_s":418.4,"text":"but it's done right it's like done but not to like where i","speaker":null,"is_sponsor":0},{"start_s":416.08,"end_s":420.88,"text":"normally would get it before a video are you sure","speaker":null,"is_sponsor":0},{"start_s":419.84,"end_s":427.68,"text":"yeah so we have the bottom bit this also known as the base yes the base yep cpu","speaker":null,"is_sponsor":0},{"start_s":425.36,"end_s":432.0,"text":"contacts the bottom here yep peltier it's pretty flat","speaker":null,"is_sponsor":0},{"start_s":429.84,"end_s":435.919,"text":"yeah i actually laughed the stuff oh okay well that explains it so","speaker":null,"is_sponsor":0},{"start_s":434.0,"end_s":441.199,"text":"yeah peltier it goes on there uh which way not sure we need to turn it on to find","speaker":null,"is_sponsor":0},{"start_s":438.88,"end_s":445.36,"text":"that out and there's okay there's a little trace that's in there that's","speaker":null,"is_sponsor":0},{"start_s":442.639,"end_s":448.8,"text":"where our thermal couple goes okay neat there we go we've got the","speaker":null,"is_sponsor":0},{"start_s":447.28,"end_s":453.68,"text":"all soft bit yep also left all the surfaces were left","speaker":null,"is_sponsor":0},{"start_s":451.44,"end_s":458.319,"text":"in this okay and then yeah this goes on there and","speaker":null,"is_sponsor":0},{"start_s":456.24,"end_s":461.919,"text":"we're good to go all right so why don't we get this mess assembled and see where","speaker":null,"is_sponsor":0},{"start_s":460.24,"end_s":466.639,"text":"we go from there yeah we basically have two tasks to do","speaker":null,"is_sponsor":0},{"start_s":463.919,"end_s":468.88,"text":"here okay one we need to make a water cooling loop","speaker":null,"is_sponsor":0},{"start_s":467.84,"end_s":474.72,"text":"and maybe equip this motherboard for","speaker":null,"is_sponsor":0},{"start_s":471.28,"end_s":478.639,"text":"sub-zero depending on how we're feeling","speaker":null,"is_sponsor":0},{"start_s":474.72,"end_s":481.759,"text":"and the other thing is this sketchy box","speaker":null,"is_sponsor":0},{"start_s":478.639,"end_s":484.319,"text":"here needs to be turned into","speaker":null,"is_sponsor":0},{"start_s":481.759,"end_s":488.8,"text":"a sketchy box that works so everything that needs to be here is","speaker":null,"is_sponsor":0},{"start_s":487.199,"end_s":493.759,"text":"there but none of it is soldered none of it's soldered yeah","speaker":null,"is_sponsor":0},{"start_s":491.36,"end_s":496.4,"text":"so they get to watch us solder and cringe again","speaker":null,"is_sponsor":0},{"start_s":494.96,"end_s":501.919,"text":"yeah they're going to be really happy about that so this right here is our solid state relay it's going to just","speaker":null,"is_sponsor":0},{"start_s":500.0,"end_s":504.84,"text":"turn our tech on and off based on how cold it is and","speaker":null,"is_sponsor":0},{"start_s":503.28,"end_s":507.84,"text":"if it's going to cause condensation and crap pretty much all that's going into","speaker":null,"is_sponsor":0},{"start_s":507.12,"end_s":514.24,"text":"there we have these two power supply leads that","speaker":null,"is_sponsor":0},{"start_s":511.039,"end_s":516.64,"text":"are just cable mod cable extensions","speaker":null,"is_sponsor":0},{"start_s":514.24,"end_s":520.0,"text":"goes in there goes the solid state relay and then","speaker":null,"is_sponsor":0},{"start_s":518.08,"end_s":524.56,"text":"out through this port here to the peltier and","speaker":null,"is_sponsor":0},{"start_s":522.56,"end_s":528.0,"text":"should be good okay so i've got a bit of an update for y'all uh first of all here","speaker":null,"is_sponsor":0},{"start_s":526.88,"end_s":531.6,"text":"is our wait uh update number two","speaker":null,"is_sponsor":0},{"start_s":530.399,"end_s":536.64,"text":"is this is the radiator alex was talking about","speaker":null,"is_sponsor":0},{"start_s":533.92,"end_s":540.64,"text":"so this actually had a dedicated video on the channel like","speaker":null,"is_sponsor":0},{"start_s":538.399,"end_s":545.04,"text":"five years ago or something like that but it's the phobia g changer","speaker":null,"is_sponsor":0},{"start_s":543.68,"end_s":550.72,"text":"1080. basically it's three triple 120 mil rads","speaker":null,"is_sponsor":0},{"start_s":549.279,"end_s":554.8,"text":"glued together to make for a nine by one twenty","speaker":null,"is_sponsor":0},{"start_s":552.56,"end_s":558.08,"text":"millimeter radiator so we're gonna we're gonna pop that","speaker":null,"is_sponsor":0},{"start_s":556.72,"end_s":562.64,"text":"like it's hot and uh","speaker":null,"is_sponsor":0},{"start_s":559.92,"end_s":566.959,"text":"it's gonna cool things down good news everyone oh what's up","speaker":null,"is_sponsor":0},{"start_s":564.64,"end_s":571.44,"text":"i found the perfect fans to use for our radiator here","speaker":null,"is_sponsor":0},{"start_s":568.399,"end_s":573.519,"text":"oh no these are actually the ones uh","speaker":null,"is_sponsor":0},{"start_s":571.44,"end_s":577.04,"text":"from whole room water cooling from the last","speaker":null,"is_sponsor":0},{"start_s":575.6,"end_s":582.72,"text":"setup that we did that was this ridiculous and","speaker":null,"is_sponsor":0},{"start_s":580.24,"end_s":587.04,"text":"uh all of the someone who disassembled it just left all of the screws like in","speaker":null,"is_sponsor":0},{"start_s":584.64,"end_s":591.839,"text":"the fans so i don't even have to go find radiator screws i just","speaker":null,"is_sponsor":0},{"start_s":589.279,"end_s":591.839,"text":"put these in","speaker":null,"is_sponsor":0},{"start_s":594.959,"end_s":598.48,"text":"just wrapping up the radiator here","speaker":null,"is_sponsor":0},{"start_s":598.64,"end_s":606.72,"text":"and that's it however many friggin watts of cooling that","speaker":null,"is_sponsor":0},{"start_s":602.839,"end_s":610.16,"text":"is these are dirty in like a really","speaker":null,"is_sponsor":0},{"start_s":606.72,"end_s":612.0,"text":"unsettling way like it's caked okay so","speaker":null,"is_sponsor":0},{"start_s":610.16,"end_s":616.16,"text":"if i said i was five minutes from water loop completion how close are we","speaker":null,"is_sponsor":0},{"start_s":614.56,"end_s":620.88,"text":"so everything in here is wired up except","speaker":null,"is_sponsor":0},{"start_s":618.88,"end_s":624.56,"text":"that we need to do the painful bit these two guys right here need to get the","speaker":null,"is_sponsor":0},{"start_s":622.16,"end_s":628.48,"text":"choppy chop and then what they get soldered together go to here and up","speaker":null,"is_sponsor":0},{"start_s":626.72,"end_s":632.88,"text":"there and we're good to go oh i see it okay yeah what else do we need to do uh","speaker":null,"is_sponsor":0},{"start_s":631.12,"end_s":635.92,"text":"besides that these two holes right here need to be","speaker":null,"is_sponsor":0},{"start_s":634.24,"end_s":639.92,"text":"tapped the rest are all tapped oh my favorite yeah all right i guess i'm","speaker":null,"is_sponsor":0},{"start_s":638.32,"end_s":645.6,"text":"gonna thread this thing wait we have a proper tap now don't we","speaker":null,"is_sponsor":0},{"start_s":642.399,"end_s":648.24,"text":"do we have a beautiful handle yes whoa","speaker":null,"is_sponsor":0},{"start_s":645.6,"end_s":652.0,"text":"yeah look at that thing look at this wow it's almost like it was","speaker":null,"is_sponsor":0},{"start_s":650.079,"end_s":656.24,"text":"made to do this i've never been this excited to have","speaker":null,"is_sponsor":0},{"start_s":653.76,"end_s":656.24,"text":"leverage","speaker":null,"is_sponsor":0},{"start_s":656.959,"end_s":661.839,"text":"it only needs to be straight enough","speaker":null,"is_sponsor":0},{"start_s":663.12,"end_s":668.88,"text":"oh okay well this is not going well","speaker":null,"is_sponsor":0},{"start_s":667.519,"end_s":674.88,"text":"um so you

those","speaker":null,"is_sponsor":0},{"start_s":732.0,"end_s":736.24,"text":"so we can disconnect it if we want got it","speaker":null,"is_sponsor":0},{"start_s":736.959,"end_s":740.959,"text":"yeah

okay","speaker":null,"is_sponsor":0},{"start_s":800.639,"end_s":807.839,"text":"so before i put this on i should show you guys the finished assembly so here's where our water cools the hot side

it","speaker":null,"is_sponsor":0},{"start_s":853.92,"end_s":861.519,"text":"on nothing died yet that's a good sign so now i'm gonna put this on

we did it so i can put this down","speaker":null,"is_sponsor":0},{"start_s":887.92,"end_s":892.24,"text":"yep okay all right so","speaker":null,"is_sponsor":0},{"start_s":890.959,"end_s":896.56,"text":"this right here is set right now it's just to 20 degrees okay but","speaker":null,"is_sponsor":0},{"start_s":895.199,"end_s":901.44,"text":"that seems fine the solid state relay actually is working","speaker":null,"is_sponsor":0},{"start_s":899.839,"end_s":906.959,"text":"like how do you know because this right here has a

you hear a click and when you put it in you can hear it go cool coming in hot","speaker":null,"is_sponsor":0},{"start_s":913.199,"end_s":919.76,"text":"what the hell well i couldn't find a big jug so i that","speaker":null,"is_sponsor":0},{"start_s":917.839,"end_s":923.68,"text":"was such a good opportunity to like plug the merch you have i have the merch

we could have used like three all right let's fill this thing","speaker":null,"is_sponsor":0},{"start_s":937.68,"end_s":942.32,"text":"okay well there's one mug down","speaker":null,"is_sponsor":0},{"start_s":941.04,"end_s":945.199,"text":"all right now the game is on","speaker":null,"is_sponsor":0},{"start_s":951.519,"end_s":957.68,"text":"oh it's not

here","speaker":null,"is_sponsor":0},{"start_s":959.12,"end_s":964.959,"text":"and they're going not just through the middle but also all the way around

wouldn't","speaker":null,"is_sponsor":0},{"start_s":996.56,"end_s":1002.399,"text":"have been quite such a disaster what how is that related at all well they","speaker":null,"is_sponsor":0},{"start_s":1001.12,"end_s":1008.16,"text":"were confident it was going to work i better they wouldn't have put a bunch of people in it yeah it worked really well","speaker":null,"is_sponsor":0},{"start_s":1005.519,"end_s":1008.16,"text":"for quite a while","speaker":null,"is_sponsor":0},{"start_s":1008.56,"end_s":1013.92,"text":"so we didn't run into this when we were using just a small peltier but it","speaker":null,"is_sponsor":0},{"start_s":1012.0,"end_s":1017.199,"text":"occurred to us that with so much power we might be running into over

so","speaker":null,"is_sponsor":0},{"start_s":1018.8,"end_s":1026.24,"text":"i thought well why don't we use the eight pin eps connector which is the

so","speaker":null,"is_sponsor":0},{"start_s":1048.799,"end_s":1054.799,"text":"all we have to do is redo the the wiring here into your adapter so it's actually","speaker":null,"is_sponsor":0},{"start_s":1052.88,"end_s":1058.88,"text":"a pretty it's almost a plug-and-play solution","speaker":null,"is_sponsor":0},{"start_s":1056.24,"end_s":1063.679,"text":"plug-in prey more like it all right good luck everybody","speaker":null,"is_sponsor":0},{"start_s":1061.76,"end_s":1069.44,"text":"oh oh temperatures dropping temperatures dropping very fast really we're at 20","speaker":null,"is_sponsor":0},{"start_s":1066.08,"end_s":1071.919,"text":"degrees 19 don't touch that","speaker":null,"is_sponsor":0},{"start_s":1069.44,"end_s":1076.72,"text":"we're at 16

because","speaker":null,"is_sponsor":0},{"start_s":1078.72,"end_s":1084.0,"text":"maybe the relay wasn't the problem before well if we want to just jam the","speaker":null,"is_sponsor":0},{"start_s":1082.48,"end_s":1087.36,"text":"other ones into this then the other power supply might work wait oh right","speaker":null,"is_sponsor":0},{"start_s":1085.919,"end_s":1090.16,"text":"the relay is a good right yeah we want the relay yeah okay","speaker":null,"is_sponsor":0},{"start_s":1089.2,"end_s":1093.28,"text":"okay oh man i told you this is hard to take","speaker":null,"is_sponsor":0},{"start_s":1092.24,"end_s":1099.36,"text":"out so theoretically this turns on yeah","speaker":null,"is_sponsor":0},{"start_s":1096.32,"end_s":1101.52,"text":"drops to 15 degrees and then the relay","speaker":null,"is_sponsor":0},{"start_s":1099.36,"end_s":1104.559,"text":"stops it really okay all right it's on","speaker":null,"is_sponsor":0},{"start_s":1103.2,"end_s":1109.6,"text":"okay the temperature's dropping real fast now so we just went past","speaker":null,"is_sponsor":0},{"start_s":1107.52,"end_s":1115.089,"text":"15 degrees oh yep and the thing the thing hit turned off","speaker":null,"is_sponsor":0},{"start_s":1115.76,"end_s":1125.52,"text":"oh this definitely needs some tuning though oh yeah so just auto-tune if you

late but um at least we got the video done right no no we didn't we didn't actually it was all for nothing really frustrated we are doing a thermoelectric cooled computer but instead of doing it kind of the um like the the janky way well to be clear it's still janky it's probably the jankiest thing we've ever made we recently did a video on peltier or tech cooling with the basic conclusion being that it's a giant boatload of suck we spent about three hundred dollars to get pretty much the same no actually worse performance worse than with a standard water cooling radiator and at the fantastic cost of a couple hundred watts of power consumption so we've taken all those learnings and we have crumpled them into a big ball and put them in a fire because today's video is all about taking peltier cooling and amping it up a notch pun intended this right here is a 545 watt peltier thermoelectric cooling module so we are going to pump a whack ton of current through it we're gonna have a hot side we're gonna have a cold side and we are gonna have potentially a real good time or a real bad time either way it's a great video right speaking of great videos this great video is brought to you by our sponsor i fix it the ifixit marlin screwdriver set features five specialty precision screwdrivers and you can get yours at the link in the video description so i noticed that you designed a water block is there a reason that other than flexing the new workshop here that we didn't just use a standard water block and put it on top of the tech yeah so a water block like this even though it looks size wise like it's it should be a pretty good yeah cpus only on the die they really create a lot of heat so water blocks only really cool the center right so the actual fin structure of a typical cpu water block is only about this big so what happens then to our tech if we only cool the center of it it just won't be as efficient and it's going to get really hot around the edges so we had to design this fairly massive block like if you it's hard to get a sense of the scale when we're looking at it like this so how big is it the scale like these mounting holes right here yeah are the same but but the actual size we're actually going almost right to it so it's quite a bit larger yeah it's like about this big so we have a 65 millimeter inner channel thing which is just a bit larger than the diameter of this so it should work pretty well unless it doesn't another reason we had to design our own block was that it needs to have some special functionality like okay it's great in theory to say you stick this on top to cool the hot side and then the cpu gets cooled by the cold side but what keeps this in place not just in place but clamped against the cooling element so that it gets optimal thermal transfer well that's where this type of sandwich design comes in so you can see we've got our cooling element here on the top and then you can actually see this very nice attention to detail by the way thank you i like this with the leads going in and everything you can see the peltier element is sandwiched in between then we've got these right here these bolt throughs are going to hold these pieces together really really tightly and bind them to this this cold plate at the bottom so for much the same reason as we can't just attach a tiny cooling element to the top of the hot side of the peltier and expect optimal efficiency we can't take the cold side of the peltier and put that against a tiny little cpu and hope that we're getting the most cooling out of it so we need to have something to spread the cooling and that's going to be another copper plate on the bottom that is also sandwiched around it yeah so another problem that we have is that if you just put this on full bore like if you just attach it to a power supply sure it's going to cool down really really fast and really cold yeah so we could end up with condensation um i mean really condensation yeah condensation lots of water around your cpu not a great time so that's why we have this guy right here it's a pid controller and do you know what pid is actually i don't know what it stands for um proportional integral and derivative okay so in a nutshell this is like an on off switch temperature goes in and it says yes that is okay or no that is not okay and if the temperature is okay then it ah sends a signal to this guy and says don't turn on the peltier and if the temperature is not okay it's too high it's higher than what we want then it'll say hey he'll kick on and this will turn on our block yeah so that's all well and good although it's a bit sketchy to just have all of that electronic stuff put on the table yeah so all that's going in this nice little box right here fun which you might have noticed this doesn't quite fit so we can either cut a hole in the top and have a big old fan or we can cut a slot and have it just sticking out the side i'm a fan of that one because it's easier okay sticking out the side cool you might be looking at this rather primitive block and thinking there's no way that's going to cool a 545w peltier so i'm going to prove it should be fine using solidworks flow simulation for the simulation we've got a 545 watt heat source some thermal paste and a fluid input with a flow rate of a d5 pump the only real assumption that i've made is that the water would reach a steady state temperature of about 42 degrees which seems reasonable enough given the huge radiator that we're using after running the simulation we can see that the flow does a reasonably good job of going through the fins and the water resistant temperature by about two degrees while making its way from one side to the other the temperature of the peltier rises quickly at first but it hits steady state at around 54 degrees after a minute or two which seems slightly low to me but basically confirms that if we have a problem it's probably not due to bad cooling oh man it's gonna be like the most full send video we've done in a while but it's done right it's like done but not to like where i normally would get it before a video are you sure yeah so we have the bottom bit this also known as the base yes the base yep cpu contacts the bottom here yep peltier it's pretty flat yeah i actually laughed the stuff oh okay well that explains it so yeah peltier it goes on there uh which way not sure we need to turn it on to find that out and there's okay there's a little trace that's in there that's where our thermal couple goes okay neat there we go we've got the all soft bit yep also left all the surfaces were left in this okay and then yeah this goes on there and we're good to go all right so why don't we get this mess assembled and see where we go from there yeah we basically have two tasks to do here okay one we need to make a water cooling loop and maybe equip this motherboard for sub-zero depending on how we're feeling and the other thing is this sketchy box here needs to be turned into a sketchy box that works so everything that needs to be here is there but none of it is soldered none of it's soldered yeah so they get to watch us solder and cringe again yeah they're going to be really happy about that so this right here is our solid state relay it's going to just turn our tech on and off based on how cold it is and if it's going to cause condensation and crap pretty much all that's going into there we have these two power supply leads that are just cable mod cable extensions goes in there goes the solid state relay and then out through this port here to the peltier and should be good okay so i've got a bit of an update for y'all uh first of all here is our wait uh update number two is this is the radiator alex was talking about so this actually had a dedicated video on the channel like five years ago or something like that but it's the phobia g changer 1080. basically it's three triple 120 mil rads glued together to make for a nine by one twenty millimeter radiator so we're gonna we're gonna pop that like it's hot and uh it's gonna cool things down good news everyone oh what's up i found the perfect fans to use for our radiator here oh no these are actually the ones uh from whole room water cooling from the last setup that we did that was this ridiculous and uh all of the someone who disassembled it just left all of the screws like in the fans so i don't even have to go find radiator screws i just put these in just wrapping up the radiator here and that's it however many friggin watts of cooling that is these are dirty in like a really unsettling way like it's caked okay so if i said i was five minutes from water loop completion how close are we so everything in here is wired up except that we need to do the painful bit these two guys right here need to get the choppy chop and then what they get soldered together go to here and up there and we're good to go oh i see it okay yeah what else do we need to do uh besides that these two holes right here need to be tapped the rest are all tapped oh my favorite yeah all right i guess i'm gonna thread this thing wait we have a proper tap now don't we do we have a beautiful handle yes whoa yeah look at that thing look at this wow it's almost like it was made to do this i've never been this excited to have leverage it only needs to be straight enough oh okay well this is not going well um so you won't be able to see it very well but basically i'm checking if the o-ring is squeezed against the plexi there and it looks like they are squeezed all the way around all right i think i got him this box right here might be the sketchiest thing i've ever done like look at this it's just it's a bit of a mess it's a bit of a mess and we're putting like there's ac power in here we've got what's going to be nearly like 600 watts going through freaking lever nuts are we going to start a fire um it's all within the rating okay these are 32 amps rated at that and we're expecting 32 amps so so where do i connect this to um so we need to put some wires onto here yep and then those i was thinking maybe just lever not them to those so we can disconnect it if we want got it yeah soon very soon okay this is probably the cold side so we're gonna gamble and i'm just gonna start assembling it all right uh all right here comes all the thermal goop this is disgusting this stuff is nasty wait cold side heat absorb oh crap i put it in the upside down oh no oh come on how could i do that we're gonna have to give up and start rancho at some point here though yeah so what was that about not wanting to do this project the sketchy way because i seem to recall you saying something about that oh i just remember like at the start i had so many aspirations so this would not be totally sketchy i want to see this thing fire up yeah same and i'm at the point where even if it is literal fire i will settle for it okay so before i put this on i should show you guys the finished assembly so here's where our water cools the hot side of the peltier which is sandwiched in there and then here is where the cold side cools our cpu um alex i can just put this on now right yep and you're good to uh do your soldering on the leads for the tech just like on here right um yeah sure good because that's what you're doing okay this is not an amazing mounting mechanism but i happen to have some screws that are almost exactly the right length so we are going for a hard mount that is gnarly the good news is you're going to get all that mounting pressure you wanted yep the bad news is we might crack this piece of acrylic all right well i'm going to plug this in here if i have to blast a titan rtx i'm going to be so pissed off all right so this power supply i'm going to turn it on nothing died yet that's a good sign so now i'm gonna put this on and if bad things happen i'll just flick the switch and turn it back off so three two one the fan didn't turn on should it have hmm imagine something being potentially miswired in there all right we should probably go to windshield yep okay so heat we don't want that we want cool yay we did it so i can put this down yep okay all right so this right here is set right now it's just to 20 degrees okay but that seems fine the solid state relay actually is working like how do you know because this right here has a sketchy connection yeah so if you pull it out and you hear a click and when you put it in you can hear it go cool coming in hot what the hell well i couldn't find a big jug so i that was such a good opportunity to like plug the merch you have i have the merch too i just need more you have the water bottle yeah i know but that also has my ice water in it i was drinking that so water um we could have used like three all right let's fill this thing okay well there's one mug down all right now the game is on oh it's not leaking so that's good so is there water running through that loop yep oh you can also see that the bubbles are coming in here and they're going not just through the middle but also all the way around too okay fantastic so the block design is working as intended oh my god what is going on here so that means the radiator is full which is good uh oh ball sacks my well it's a good thing those fans were dead the tech is so close to working yeah yeah are you sure not 100 because you've said it a couple times now i am slightly more confident this time that's nice if only confidence was what it took to make something work then the uh hindenburg probably wouldn't have been quite such a disaster what how is that related at all well they were confident it was going to work i better they wouldn't have put a bunch of people in it yeah it worked really well for quite a while so we didn't run into this when we were using just a small peltier but it occurred to us that with so much power we might be running into over current protection limits on the pci express connector so i thought well why don't we use the eight pin eps connector which is the cpu power connector instead and see if we can overcome the problem that way and what's really convenient is that this is not by design and you shouldn't ever do this if you can avoid it but fun fact you can jam an eps mail connector into a pci express um female receptacle and all the pins will make contact it's just really like it's kind of a bit to get it back out so all we have to do is redo the the wiring here into your adapter so it's actually a pretty it's almost a plug-and-play solution plug-in prey more like it all right good luck everybody oh oh temperatures dropping temperatures dropping very fast really we're at 20 degrees 19 don't touch that we're at 16 degrees yeah that's definitely working okay whoa so we're ready to rock yes should we see if our relay works because maybe the relay wasn't the problem before well if we want to just jam the other ones into this then the other power supply might work wait oh right the relay is a good right yeah we want the relay yeah okay okay oh man i told you this is hard to take out so theoretically this turns on yeah drops to 15 degrees and then the relay stops it really okay all right it's on okay the temperature's dropping real fast now so we just went past 15 degrees oh yep and the thing the thing hit turned off oh this definitely needs some tuning though oh yeah so just auto-tune if you hold that just do make your computer videos that was not necessary achieve this okay and so the relay doesn't work alex i'm not totally sure did you just have it configured wrong does our oh does this thing read negative temperatures it seems like no oh come on that's great so because the relay now serves absolutely no purpose we don't have to deal with its uh limitation when it comes to reading negative temperature values check it out the old yellow and gray multi-logger thermometer makes an appearance it's back from the dead baby okay so cpu temps are dropping dropping we're at 15 11. we're three on the tech so we need to hit this thing with a load because we at idle like this is such cooling overkill that it is ridiculous like we can't we can't keep turning it on and off like this all the time uh so which one classroom i'm gonna maybe bmw what's the speed at right now uh okay it looks stuck yeah okay so bmw cpu here we go okay here we go cpu temps are up in the 50s 60s 70s get that tech turned on baby oh yeah it's on did we overwhelm it already oh yeah it's just 34 35 we're at like 85 degrees come on there's no way that we did all of this for it to just crap out like that oh we're throttling we're throttling we throttled son we overwhelmed the tech okay hold on a second let's stop the stop the blender stop the fire wait hold on stop escape yeah now it's dropping like from 40 it's dropping fast alex insisted we get our hands on a variable voltage power supply so here's a 15 to 24 volt power supply let's fire this thing up and you need to be more excited we're doing it we're testing it it's going to work it's going to be great i don't actually believe what i just said okay testing oh it's going up it's going up fast but i can turn up the voltage now right we're at 330 watts now 380 watts how how's your temperatures there we're at 22 volts we're at 373 watts it's going up fast there i actually didn't bother okay i'm just going to stop this test hold on we're at 24 volts 744 watts i would probably keep the test on we are dropping temperature quickly here we are at 22 we are 21. we're at 20 degrees 19 degrees that's the heat on the block here whoa that copper is hot okay the pump's running right no yeah the pump's running holy crap all right we're at 900 watts on this thing all right we're already up to 90 degrees on the cpu so if we're doing 90 watts on the telp 900 we're doing 900 watts oh yeah we're at 105 degrees that copper's hot something smells like burning we got to turn this off okay if we're drawing like 900 watts and it still is thermal throttling there's no way techs are ever going to cool at 7 900. i told you yeah so in a nutshell um tech cooling is and was a bad idea and everything that i told you in your first week here was true yeah it's a bad idea and nobody should do it because even with a super high powered tech the power inefficiency the fact that you need so much more cooling capacity because you have to cool the cpu and all the waste heat off of your tech the complexity of the setup and the relays and crap that you need to set up in order to avoid condensation and the fact that you are still going to be limited to like high-end consumer processors at best that you can actually effectively cool with attack all these limitations oh yeah cost need i go on mean that tech cooling is a pretty bad time there's no way we can just finish like this do you need a beautiful website without all the hassle well squarespace has got you
