two","speaker":null,"is_sponsor":0},{"start_s":228.799,"end_s":234.56,"text":"fan with no bottom so this is kind of the test where like","speaker":null,"is_sponsor":0},{"start_s":233.2,"end_s":239.439,"text":"if they just put a fan in there this is how good it would perform all right with the unit open we've got a great look

got","speaker":null,"is_sponsor":0},{"start_s":246.239,"end_s":252.72,"text":"some little folded metal fins over it it's like it's a heat sink and then","speaker":null,"is_sponsor":0},{"start_s":251.12,"end_s":257.84,"text":"here's the fan that they went and they put it in the","speaker":null,"is_sponsor":0},{"start_s":255.12,"end_s":261.919,"text":"laptop so like it has a fan they just didn't bother to have the fan draw

has","speaker":null,"is_sponsor":0},{"start_s":264.08,"end_s":269.6,"text":"yet offered up a clear unbelievable explanation for why they","speaker":null,"is_sponsor":0},{"start_s":268.16,"end_s":273.44,"text":"would have done this they went and they they put the heatsink","speaker":null,"is_sponsor":0},{"start_s":271.759,"end_s":277.68,"text":"and the fan in there they just didn't bring them together you know run number","speaker":null,"is_sponsor":0},{"start_s":275.36,"end_s":281.6,"text":"three definitely going slower it's making its way to 100 degrees slower now","speaker":null,"is_sponsor":0},{"start_s":280.16,"end_s":286.88,"text":"we're having a look at the heart of the system here that is","speaker":null,"is_sponsor":0},{"start_s":283.68,"end_s":290.08,"text":"almost 10 degrees lower maybe not 10 but","speaker":null,"is_sponsor":0},{"start_s":286.88,"end_s":292.56,"text":"more than five for sure dang macbook you","speaker":null,"is_sponsor":0},{"start_s":290.08,"end_s":295.68,"text":"fly our package power consumption is higher than last time which means i'm","speaker":null,"is_sponsor":0},{"start_s":294.0,"end_s":300.639,"text":"expecting better performance but our utilization is only about 87 percent","speaker":null,"is_sponsor":0},{"start_s":299.04,"end_s":304.0,"text":"and of course we did hit 100 degrees here so it looks like it looks like","speaker":null,"is_sponsor":0},{"start_s":302.479,"end_s":309.68,"text":"anyway that we are thermally limited right now why is it asking for 3.4 gigahertz it's","speaker":null,"is_sponsor":0},{"start_s":307.28,"end_s":314.72,"text":"got to know it's not going to get that there it is 1088.","speaker":null,"is_sponsor":0},{"start_s":312.8,"end_s":318.88,"text":"what's that like another 4 but we can do better","speaker":null,"is_sponsor":0},{"start_s":316.24,"end_s":324.08,"text":"so far we've got about an 8 uplift in performance over our stock configuration","speaker":null,"is_sponsor":0},{"start_s":322.08,"end_s":328.0,"text":"but that's without changing out our thermal compound so that's going to be","speaker":null,"is_sponsor":0},{"start_s":326.56,"end_s":333.199,"text":"the next leg of our journey we're going to go with Noctua nth2 thermal compound","speaker":null,"is_sponsor":0},{"start_s":330.88,"end_s":338.479,"text":"see i'm pushing that down flat it seems like it's not actually designed to sit","speaker":null,"is_sponsor":0},{"start_s":335.52,"end_s":342.479,"text":"right against the die that makes no sense i mean it makes sense if you want","speaker":null,"is_sponsor":0},{"start_s":340.88,"end_s":348.96,"text":"the thermal performance to not be as good as it could be do you wanna just put it back on and like give it a wiggle","speaker":null,"is_sponsor":0},{"start_s":347.36,"end_s":353.919,"text":"it's not gonna do anything because it doesn't go down far enough","speaker":null,"is_sponsor":0},{"start_s":352.479,"end_s":358.72,"text":"see so i can i can wiggle it all i want but it's","speaker":null,"is_sponsor":0},{"start_s":356.8,"end_s":361.68,"text":"it can't go down any farther hmm","speaker":null,"is_sponsor":0},{"start_s":360.639,"end_s":366.96,"text":"see oh shoot are we taking a trip to the","speaker":null,"is_sponsor":0},{"start_s":363.68,"end_s":369.6,"text":"milling machine i think we have to huh","speaker":null,"is_sponsor":0},{"start_s":366.96,"end_s":373.68,"text":"that's fun i knew you'd like that recessed those a little bit please don't","speaker":null,"is_sponsor":0},{"start_s":371.52,"end_s":378.96,"text":"ruin it that's the plan stressed out alex","speaker":null,"is_sponsor":0},{"start_s":376.639,"end_s":382.24,"text":"you and me both they don't exactly sell this replacement part on apple.com have","speaker":null,"is_sponsor":0},{"start_s":381.039,"end_s":386.72,"text":"you tried getting the apple card maybe they have it then now it's touching","speaker":null,"is_sponsor":0},{"start_s":384.639,"end_s":389.759,"text":"we want to take this nut right here that controls the depth","speaker":null,"is_sponsor":0},{"start_s":389.919,"end_s":396.479,"text":"it's nice and snug there we're going to back it off just","speaker":null,"is_sponsor":0},{"start_s":393.36,"end_s":397.919,"text":"that much i'm uncomfortable yeah i","speaker":null,"is_sponsor":0},{"start_s":396.479,"end_s":402.199,"text":"i was not thinking we'd be doing this here today well i guess","speaker":null,"is_sponsor":0},{"start_s":402.639,"end_s":411.91,"text":"i can't look but i can't look away","speaker":null,"is_sponsor":0},{"start_s":413.84,"end_s":423.36,"text":"okay that's lots that's enough","speaker":null,"is_sponsor":0},{"start_s":423.36,"end_s":429.84,"text":"oh i think that's more than we needed i hate this why did i buy you this you","speaker":null,"is_sponsor":0},{"start_s":428.0,"end_s":433.52,"text":"know what sucks though alex is while we might be getting better contact we now","speaker":null,"is_sponsor":0},{"start_s":431.84,"end_s":437.199,"text":"have what i would consider to be a significant amount less copper on

what's there the worst part is this was supposed to be the like reasonable do it at home","speaker":null,"is_sponsor":0},{"start_s":443.52,"end_s":447.84,"text":"option we had no way of knowing that they were going to have such a","speaker":null,"is_sponsor":0},{"start_s":446.56,"end_s":453.599,"text":"boneheaded i mean i don't want to call it a flaw because it's clearly","speaker":null,"is_sponsor":0},{"start_s":450.639,"end_s":457.039,"text":"intentional but design decision we use thermal pads because they allow

i'm aware of other than just","speaker":null,"is_sponsor":0},{"start_s":470.8,"end_s":476.319,"text":"not wanting it to perform well i don't get it well i'd say it's just cheaper","speaker":null,"is_sponsor":0},{"start_s":474.56,"end_s":480.56,"text":"for them to make all they had to do was put a spring on each one of those screws","speaker":null,"is_sponsor":0},{"start_s":478.479,"end_s":486.24,"text":"into a spring mount like everyone else ever got a little wiggle wobble","speaker":null,"is_sponsor":0},{"start_s":483.039,"end_s":488.639,"text":"let's have a look here oh yeah","speaker":null,"is_sponsor":0},{"start_s":486.24,"end_s":492.56,"text":"that is way better now we just need to be careful not to accidentally over","speaker":null,"is_sponsor":0},{"start_s":490.56,"end_s":496.0,"text":"tighten these because that is a definite possibility","speaker":null,"is_sponsor":0},{"start_s":494.0,"end_s":500.8,"text":"if it's not immediately at 100 degrees then it's way better we're still at

really okay so that actually is worse","speaker":null,"is_sponsor":0},{"start_s":508.16,"end_s":512.56,"text":"than before with the fan but the temps were","speaker":null,"is_sponsor":0},{"start_s":511.44,"end_s":516.399,"text":"definitely better so i feel like it might just be the turbo profile but","speaker":null,"is_sponsor":0},{"start_s":514.479,"end_s":520.56,"text":"that's better than our first run isn't it yeah that's three percent better even","speaker":null,"is_sponsor":0},{"start_s":518.479,"end_s":526.959,"text":"if i'm not sure exactly what to make of that the show must go on so let's move","speaker":null,"is_sponsor":0},{"start_s":523.12,"end_s":529.2,"text":"on to our next idea which is","speaker":null,"is_sponsor":0},{"start_s":526.959,"end_s":534.32,"text":"expanding the amount

seems like apple's using like a thermal insulator","speaker":null,"is_sponsor":0},{"start_s":544.56,"end_s":549.92,"text":"in order to keep the bottom of the computer cooler so i guess we're going","speaker":null,"is_sponsor":0},{"start_s":548.24,"end_s":554.16,"text":"to have to pull that off first yep that goes rib to be clear the inclusion of","speaker":null,"is_sponsor":0},{"start_s":552.24,"end_s":558.56,"text":"this insulator here is not something that i actually oppose the difference","speaker":null,"is_sponsor":0},{"start_s":556.56,"end_s":564.36,"text":"between you know something being comfortable against your skin and being","speaker":null,"is_sponsor":0},{"start_s":561.04,"end_s":567.2,"text":"literally burned by it is actually a","speaker":null,"is_sponsor":0},{"start_s":564.36,"end_s":573.2,"text":"surprisingly

we","speaker":null,"is_sponsor":0},{"start_s":579.44,"end_s":584.24,"text":"might as well wing it hard these kinds of pads are hardly the most thermally","speaker":null,"is_sponsor":0},{"start_s":583.04,"end_s":588.48,"text":"conductive material but they're obviously better than an insulator

if the bottom of the chassis gets above 46 degrees then we're bad if it","speaker":null,"is_sponsor":0},{"start_s":594.959,"end_s":601.36,"text":"stays below that then we're all good 40 degrees","speaker":null,"is_sponsor":0},{"start_s":599.2,"end_s":605.92,"text":"now that's a hot bottom no that's actually","speaker":null,"is_sponsor":0},{"start_s":602.839,"end_s":608.08,"text":"fine well it's also not done yet","speaker":null,"is_sponsor":0},{"start_s":605.92,"end_s":611.279,"text":"yeah but like 40 degrees is totally comfortable well let's see how","speaker":null,"is_sponsor":0},{"start_s":609.519,"end_s":616.24,"text":"comfortable 43 degrees is like a bit uncomfortable 46 as you bring it too bad","speaker":null,"is_sponsor":0},{"start_s":613.519,"end_s":621.76,"text":"yeah we are still under 75 degrees what the hell","speaker":null,"is_sponsor":0},{"start_s":619.04,"end_s":626.399,"text":"well you got so little heat sink area and then you go and spread all that heat","speaker":null,"is_sponsor":0},{"start_s":624.32,"end_s":630.0,"text":"out over this giant piece of aluminum yeah it","speaker":null,"is_sponsor":0},{"start_s":628.24,"end_s":633.279,"text":"makes sense it would do a little better it did so much better when you just had","speaker":null,"is_sponsor":0},{"start_s":631.68,"end_s":636.76,"text":"the heatsink mounted properly and it probably has a tiny bit more

ready","speaker":null,"is_sponsor":0},{"start_s":645.44,"end_s":653.04,"text":"11 55 we never cracked 80 degrees so that's a","speaker":null,"is_sponsor":0},{"start_s":649.76,"end_s":654.64,"text":"14 improvement that is stock freaking","speaker":null,"is_sponsor":0},{"start_s":653.04,"end_s":657.839,"text":"nuts hold on i'm gonna start it running again just so that it doesn't really get","speaker":null,"is_sponsor":0},{"start_s":656.32,"end_s":663.76,"text":"a chance to cool down too much i want to see what our hot bottom

denying the macbook air 2020 is a pretty sleek little machine except for one small flaw instead of doing what every other laptop manufacturer ever does and put a fan right next to the CPU where the majority of the heat is generated apple opted to put the fan data over yonder somewhere leaving the CPU with only about 10 watts of cooling capacity to work with how much performance did they leave on the table to find out the answer to that we have collected this bin of cooling apparatus with everything from upside down air things to water cooling pumps to this tray which you guys might recognize from our video from several years back water cooling the original macbook 2015 by actually submerging it in water yes my friends today is gonna be a lot of fun and it's brought to you by ting why pay for what you're not going to use with ting you only pay for the mobile data that you use and you can learn more at the link in the video description to tell if our wacky cooling solutions are doing anything we will first need to establish a performance baseline running our macbook air which is a quad core eight thread CPU with no aids whatsoever i'm just going to fire up Intel power gadget here and you can also see we've got a quad core 8 thread macbook pro 13 inch running right next to it now it does run a different CPU but it should give us some idea of what we might strive for with a properly cooled chip looking at the power draw of these cpus our macbook pro starts by shooting up to about 40 45 watts and then dips down closer to 30 35 and finishes out the test there so there's no way that a 25 watt peak CPU is going to be able to match that in terms of performance but you can see that over time we fall down as low as 10 watts so i think we should be able to close the gap a fair bit here 100 degrees that seems perfectly reasonable actually they both run at 100 degrees just this one doesn't have a fan attached to it 1016 points darn it about half the speed let's try and close that gap cooling method number one a stand well and a fan oh and we're gonna add a fan to it put that there yeah that's why the the rubber chummies are on it that's pretty cheesy so between 40 and 45 we'll consider that baseline before we start each test yeah sounds good is that reasonable okay so here we go 1016 so score to beat conspiracy theory time tell me i'm wrong here apple has been sandbagging the performance of their Intel based macbooks for years now so that when they announce the ARM-based macbooks they can be like bam it runs at like half the temperature no no applause nothing all right it is amazing how quickly this thing shoots up to 100 degrees isn't it it's pretty much instant how can it not love itself if itself is so hot hey got on lttstore.com okay you told me this was gonna work i don't think this is working we're down to like 11.6 watts already so tell me brandon where do you think the CPU is i don't know Linus in the middle of the pc could it be here no or here no 10 34. all right well so much for this idea working hey that's a two percent increase two percent all right we're gonna have to get more extreme what's test number two fan with no bottom so this is kind of the test where like if they just put a fan in there this is how good it would perform all right with the unit open we've got a great look at what we were talking about before so here's the CPU right under this tiny little sort of a heat sink so it's got some little folded metal fins over it it's like it's a heat sink and then here's the fan that they went and they put it in the laptop so like it has a fan they just didn't bother to have the fan draw air over the heatsink to cool the CPU before exhausting it i don't think anyone has yet offered up a clear unbelievable explanation for why they would have done this they went and they they put the heatsink and the fan in there they just didn't bring them together you know run number three definitely going slower it's making its way to 100 degrees slower now we're having a look at the heart of the system here that is almost 10 degrees lower maybe not 10 but more than five for sure dang macbook you fly our package power consumption is higher than last time which means i'm expecting better performance but our utilization is only about 87 percent and of course we did hit 100 degrees here so it looks like it looks like anyway that we are thermally limited right now why is it asking for 3.4 gigahertz it's got to know it's not going to get that there it is 1088. what's that like another 4 but we can do better so far we've got about an 8 uplift in performance over our stock configuration but that's without changing out our thermal compound so that's going to be the next leg of our journey we're going to go with Noctua nth2 thermal compound see i'm pushing that down flat it seems like it's not actually designed to sit right against the die that makes no sense i mean it makes sense if you want the thermal performance to not be as good as it could be do you wanna just put it back on and like give it a wiggle it's not gonna do anything because it doesn't go down far enough see so i can i can wiggle it all i want but it's it can't go down any farther hmm see oh shoot are we taking a trip to the milling machine i think we have to huh that's fun i knew you'd like that recessed those a little bit please don't ruin it that's the plan stressed out alex you and me both they don't exactly sell this replacement part on apple.com have you tried getting the apple card maybe they have it then now it's touching we want to take this nut right here that controls the depth it's nice and snug there we're going to back it off just that much i'm uncomfortable yeah i i was not thinking we'd be doing this here today well i guess i can't look but i can't look away okay that's lots that's enough oh i think that's more than we needed i hate this why did i buy you this you know what sucks though alex is while we might be getting better contact we now have what i would consider to be a significant amount less copper on the heatsink like we didn't remove much but compared to what's there the worst part is this was supposed to be the like reasonable do it at home option we had no way of knowing that they were going to have such a boneheaded i mean i don't want to call it a flaw because it's clearly intentional but design decision we use thermal pads because they allow for greater tolerances in things like surface mount components like like a memory chip to do it with a dye like this where the manufacturing tolerances are so tight there's no reason for it that i'm aware of other than just not wanting it to perform well i don't get it well i'd say it's just cheaper for them to make all they had to do was put a spring on each one of those screws into a spring mount like everyone else ever got a little wiggle wobble let's have a look here oh yeah that is way better now we just need to be careful not to accidentally over tighten these because that is a definite possibility if it's not immediately at 100 degrees then it's way better we're still at 17 watts package power huh and only 90 degrees really okay so that actually is worse than before with the fan but the temps were definitely better so i feel like it might just be the turbo profile but that's better than our first run isn't it yeah that's three percent better even if i'm not sure exactly what to make of that the show must go on so let's move on to our next idea which is expanding the amount of cooling surface area that the machine has by putting a thermal pad in between this heatsink here and the chassis it actually seems like apple's using like a thermal insulator in order to keep the bottom of the computer cooler so i guess we're going to have to pull that off first yep that goes rib to be clear the inclusion of this insulator here is not something that i actually oppose the difference between you know something being comfortable against your skin and being literally burned by it is actually a surprisingly small amount yeah like 43 degrees is what you shower at and 46.7 will burn you in 35 minutes 50 degrees will burn you in one minute okay how how many layers thick should we go here boys sure why not if we're gonna wing it we might as well wing it hard these kinds of pads are hardly the most thermally conductive material but they're obviously better than an insulator for trying to cool the CPU at the cost of the user so if the bottom of the chassis gets above 46 degrees then we're bad if it stays below that then we're all good 40 degrees now that's a hot bottom no that's actually fine well it's also not done yet yeah but like 40 degrees is totally comfortable well let's see how comfortable 43 degrees is like a bit uncomfortable 46 as you bring it too bad yeah we are still under 75 degrees what the hell well you got so little heat sink area and then you go and spread all that heat out over this giant piece of aluminum yeah it makes sense it would do a little better it did so much better when you just had the heatsink mounted properly and it probably has a tiny bit more mounting pressure now 43.9 oh it's getting hot it's getting hot it's a hot bottom results coming in alex you ready 11 55 we never cracked 80 degrees so that's a 14 improvement that is stock freaking nuts hold on i'm gonna start it running again just so that it doesn't really get a chance to cool down too much i want to see what our hot bottom temperatures ended up at 46. yeah you're getting burned territory now yep that's that's too hot that's not comfortable now like lots of gaming laptops will be hotter than that on the bottom well i mean it doesn't have to be like that they could have put a fan on it yeah that was an option so much performance left on the table though it's clear that to reach our next performance tier we need to do something about the cooling of the chassis itself that is where this comes in yes my friends i would like to do a recreation of our 2015 experiment immersing the laptop we really should not do this in water i don't think we should do that at all well what's your brilliant idea we water cool it so i got this little thing right here off of amazon it was 17 amazon lies yes you've been shopping on aliexpress again it was 17 and it says laptop water cooling that's it no documentation this is all that came in the box i think you can do the job way better than that cookie sheet right there okay i'm gonna go get water for this look it's not like the thing died last time yeah but like you can fall off your motorcycle on the highway and not die just mean you want to do it again that is a false equivalency it wasn't even damaged you could just you know slide along the road and be like oh it's fine next time i definitely won't turn into jam so there's that really yeah huh you know what i think you might be right this might actually perform better than putting it in non-frozen water but we could also put it directly in frozen water and maybe kill it big brain time that's what the kids say right big brain let's just you know have some safety here safety i see you didn't even catch my pun safety i see oh that's chilly boys is it zero degrees give or take it's hard to tell because of like emissivity issues or whatever are you able to see like a cold spot on the macbook now it's chilly ah nope it's still hot huh i mean i'm sure the bottom is a bit of a different oh yeah the bottom's a different story what's the CPU temperature right now 17 16 we're sub-ambient here we go boys what's it at it still hits 70 degrees but 16 really oh well it also spiked to 35 watts damn that's way faster than before attempts are 51 and our package power is over 16 watts still wow it really is a shame how aggressively this thing gets power limited because even though we're at 41.5 degrees right now it's still all the way down to about 13 watts package power i'm disappointed i thought keeping the thermals under control would net us significantly better performance it's just power limited yeah did our pump just stop nope it ain't flowing fast though i was really hoping it would stay up in the like 15 to 18 watts neighborhood and we were gonna see like a really big performance jump yeah cause it's like 40 degrees now definitely not thermally limited oh yeah like the top of this thing is 24 degrees it's cool to the touch so you can see this look alex's hand is actually warmer than the surface of the laptop hey do you have less blood flow in your pinky i mean we learned a lot of things today just i didn't expect this i think that none of the things that we learned today we expected the score is 11.55 so there was no real benefit from going from just putting a thermal pad on the CPU that helps the bottom of the chassis dissipate heat to putting an ice cold water block on the bottom of it that's disappointing we didn't get the result that we expected or wanted but we still learned a lot today one is that the macbook air is going to be in a completely different performance class from the macbook pro no matter what kind of cooling you put on it because a even though they've both got four cores and eight threads it is a different model of CPU and b because the macbook air just doesn't have the power delivery robustness to keep up with allowing that CPU to really stretch its legs number two is that the cooling solution on the macbook air is even worse than we thought to the point where even just removing a little bit of material from the already minuscule heatsink gave us a 20-plus degree improvement in temperatures while under sustained load unfortunately like i said we didn't get the performance improvement that we wanted from that but that's how she goes just like she goes into our sponsor ting there's no contracts no overage fees and no other carrier tricks you just pay a fair price for the
