that","speaker":null,"is_sponsor":0},{"start_s":354.72,"end_s":361.44,"text":"so ek's cryo-fuel is actually a lot more conductive than just distilled

okay","speaker":null,"is_sponsor":0},{"start_s":381.44,"end_s":387.6,"text":"so as it naturally sits for longer it'll build up a coating so it seems like in","speaker":null,"is_sponsor":0},{"start_s":385.919,"end_s":392.24,"text":"our distilled water we put the leads in and the

we're","speaker":null,"is_sponsor":0},{"start_s":398.96,"end_s":405.6,"text":"guessing that's because of the corrosion inhibitors in here are slowly

drop your CPU and GPU temps by 7 degrees celsius or it's a scam i actually don't know yet the people at go chiller claim that they have a graphy nanoparticle suspension that is 60 more thermally conductive than just normal everyday water so we're going to test it out just like i'm going to test out the segway to our sponsor thanks to our sponsor volta volta's new giga charger can charge four devices simultaneously offering either 130 watt or 200 watt fast charging depending on which model you get check it out today at the link below graphene was first discovered in 2004 and ever since then it's been theorized to be able to do basically everything well except leave the laboratory but for real though it's a fascinating material and it uh kind of smells like liquor and permanent markers graphene is basically just graphite but instead of having a 3d crystal structure it's two dimensional meaning it creates one atom thick sheets of carbon atoms in a hexagonal orientation these bonds are incredibly strong graphene is about 200 times stronger than steel but this arrangement also means atoms delocalize their electrons meaning they can move around more freely these loosey-goosey electrons is why graphene is such an incredible electrical and thermal conductor it's actually the most conductive material currently in existence so just how conductive well uh we have sheets of graphene right here and it has a thermal conductivity of 1950 watts per meter kelvin that is 20 times more than liquid metal so to show you just how thermally conductive these graphene sheets are i've got a little strip right here and if i put it down onto an ice cube i can slice into it like butter using the heat of my hands it feels like i'm touching an ice cube right now it's it's so weird can you see it on the thermal camera andy yeah it's it's so strange but these sheets have a problem because of the one atom thickness the thermal conductivity is just one directional so like this direction this direction really really good this way though through those different sheets super bad so why exactly should this stuff work for cooling your pc wouldn't having a bunch of graphite clogging up your microfins be a bit of a problem well maybe i guess we're going to find out if that is an issue but the basic principle is that you have a whole bunch of very very small very highly conductive bits suspended in the liquid and so it's kind of like the water goes over the hot bits and the graphene rapidly you know thermally conducts in which it then disperses back to the water as it's traveling between your hot bit and the radiator once you get to the radiator it very rapidly dumps all of its heat and cools down the water around it as it's going back to the CPU i guess it's about time that we just empty this out and see what actually works right yeah we're gonna empty this guy out it has ek's cryofuel in it so that's essentially just water with additives to prevent like moss growing inside of it and stuff so i think it's a pretty good comparison oh that's heavy what do you think the chances are brandon of me leaving today with my clothing unstained by either graphite or red dye two out of ten two out of ten ooh yeah that's pretty accurate fortunately ek has an easy drain port so you know draining and filling the system should in theory be pretty simple oh geez that's not how that was supposed to go oh dear i kind of do need help nope we're fine we're fine we're doing fine brandon what have you done it does smell bad i just thought of a technology that we can use there we go it looks like below the drain port they have a little spot that allows the water to get into the chassis instead of out of the chassis i would say mostly that's my fault but i thought it would work a bit better as i was saying because we have a fill port and a drain port this is going to be exceptionally easy to blow up maybe we just need several people to blow on it so keep on holding it there i'm going to blow okay is it working at all a little bit came out sure don't know how to make a muscle yeah it's a specialty of mine so in conclusion the ek fluid gaming which i said was very easy to drain in the ShortCircuit about it is not it's very difficult now our graphene coolant should be a lot more thermally conductive but graphene is also the most electrically conductive material in existence so that's not ideal for your computer i want to see what the resistance actually is so across this distance right here this is distilled water so it seems to be somewhere around i believe 10 mega ohms is what it's reading come over here to ek's cryofuel to three-ish something like that so ek's cryo-fuel is actually a lot more conductive than just distilled water and we come over to our graphene solution it's about the same as ek's cryo-fuel i don't know how much i trust these numbers i'm going to call on the engineers so yeah this is exactly what it was doing before it started in the same spot yeah so while this is cryo fuel they probably are creating a coating creating a coating oh yeah that would make sense yes okay so as it naturally sits for longer it'll build up a coating so it seems like in our distilled water we put the leads in and the resistance stays about the same whereas we put it in our cryo-fuel or graphene solution it starts going up pretty fast and we're guessing that's because of the corrosion inhibitors in here are slowly coating the leads and increasing the resistance between them so that's cool i just learned something now another thing that go chiller said is really great about their stuff is it's anti-foaming agents so foam is just terrible for your pc parts because little bubbles and stuff can form on the micro fins in your CPU or in your pump and like if it gets out of hand in the pump it can run dry and kill itself or it can be less intense but just like little bubbles appearing in your microfins and lowering the efficiency of your whole loop so i'm interested to check it out i have my highly technical you know little agitator here normally Linus is good but he's on vacation unfortunately now i tried paintbrushes no good don't agitate enough try this right here terrible result probably see the security footage of that right now ah this carry here is pretty good so if we take a look there's a lot of bubbles forming right now i'm not entirely sure that we can overcome that with the graphene solution but if we can't i'll be impressed oh now if i had to guess this will be pretty much the same as the water oh actually it's foaming a little bit you can kind of see on the top there we're getting these bubbles that are forming which we weren't really getting with the distilled water so that sort of stuff happens in your loop and it's gonna be not a great time i'm curious to see if it'll behave any differently in our graphene solution it's gonna be a bit hard to tell exactly what's going on given it's black but let's give it a go it almost seems like it's foaming a bit more um we're getting a lot of little bubbles kind of all over the place i would say that was worse so that's not a pass yeah it's like five minutes later and there still are a couple bubbles in this one nothing at all in the cryo fuel so i think they're uh their anti-foaming agent isn't too good but let's chuck her in i'm actually excited i think this is going to look friggin sweet that's why i wanted to use this computer instead of another one like we could have just built a test bench oh geez have you watched full metal alchemist this reminds me of the thing that was bad i don't remember what it's called this is freaky and like the consistency just isn't quite right yeah oh oh yeah i've been marked i'm going to be graphing possessed i don't know i don't even know it like it's shimmering it looks like it's alive it's really odd it actually looks like it's infecting the computer okay brandon can you give us some slow-mo i feel like this is going to be the strangest looking pump pull ever we're just here in the BIOS i need to change all the fans back to be full speed this seriously looks so freaking cool like i've seen black liquid in computers before but there's like somewhere between like a texture and just the void in this that is so sick i can't get over it so to test this out we're just doing the two big dirties so fermark and prime95 run them both at the same time about as brutal as you can be for a computer so just need to record the temperature 22.4 degrees that is slightly higher than it was before and then wait half an hour and find out how we did all right we're back half an hour later temperature's gone down in the room actually a little bit but the temperature has certainly gone up in the pc it looks like we're gonna have to refer to the graphs here yeah sorry uh it looks like it did nearly nothing frig it looks like in some spots it was maybe two degrees lower and the room was also a degree hotter when we ran this so maybe a max of three degrees difference but that's well within the margin of error well i wasn't happy with our test results we were within what like one two degrees and our test setup was not able to resolve that so here we go different test setup we're in Linus's office where we have control of the hvac we have a different motherboard that the vrms will not throttle on the CPU is pegged at five gigahertz all cores voltage is locked at 1.4 and this is gonna be an actually good test so we've got distilled water in here we're going to run this for half an hour come back chuck the graphene in there and with any luck it's cooler and we'll know for sure if it works i've run this twice now with the distilled water and we've gotten 76 degrees max both times and the temperature in this room is quite consistent we're also seeing 200 watts sustained for the whole half an hour on the CPU so i'm pretty happy with this let's fill it up with crapping heck yeah oh it's so warm feels nice geez brandon why did we not do this in the first place i don't know all right you are no longer needed thank you thank you for your assistance yeah that was super easy oh we're seeing again like the distilled water wasn't doing anything weird but this is foaming at the top like their anti-foaming agent sucks all right this one's for all the marbles 0.1 of a degree hotter than at the start of the last test very happy with that this test is actually good so no excuses this time so it's been half an hour and it does look like that we are one degree cooler on our CPU with this test setup problem is we're also one degree cooler in the room so yeah let's take a look at the logs but it's not looking great ah this might have actually done something it's only one or two degrees difference at first it was even more but it is enough like if you look at this graph like just i think it might have actually done something brandon oh my gosh that's shocking honestly let's see here let's go like individual core and see what they'd here's core four same thing it is noticeably lower and let's change just for fun to our other water file since i ran that twice it's exactly the same it is lower well yeah i'm pretty glad that i redid our testing because this does show an improvement it's not massive but like three four degrees is measurable in our test setup that we have here so it does do something it's not complete snake oil and it looks really freaking cool like it's legitimately the coolest looking coolant i've ever seen so yeah i like it i want some more go chiller send us some mostly because it looks sick but it doesn't hurt your performance and maybe improves it so like awesome and you know
