Of course I'm going to try this!
MWAHAHAHAHAHA
Lets all try this, is what I got from the video.

"I hate thermal paste. It gets everywhere." -Jay Skywalker
Christopher Morgado the wild prequel meme always makes my day
Thank you for this. Very good meme
is it coarse and rough?
I was literally reading this as he said it
The quote is 'I don't like sand', Anakin 'hates' Obi-Wan. Boy, I sure hope somebody got fired for that blunder🤓
The ability of a material to conduct heat increases exponentially with distance. A pad makes sense when you are closing an air gap, because 3mm of pad is a whole lot better than 3mm of air, but when you put that 3mm of pad in between two metal surfaces, that 3mm pad is infinitely wose than a tiny thickness of thermal paste. 3mm of pad is also going to be a whole lot worse than the microscopic valleys in the two metal surfaces of air.
Also, vrms reach high temperatures, but they don't output that much heat compared to a cpu. That overclocked 8700k is going to be well over its rated 95w of heat at stock settings, a competent vrm on a high end board would be outputting closer to 40w (Gamer's Nexus often releases videos with buildzoid with vrm analysis where the heat output is calculated). That 40w is also going to be spread out over caps, chokes, and mosfets, so the heat is spread over a much, much larger surface area (2x the heat spreader easily on many of the overbuilt high end ones). The cpu is putting out more than twice as much heat in half the area, so it is obviously much harder to cool.)
This is correct! In this case distance is the key. The thermal resistance of a system (heat source + paste/pad + cooler) is exponentially proportional to the distance that the heat need to “travel”.
NOOOO IT IS NOT EXPONENTIAL! IS PROPORTIONAL TO THE INVERSE OF THE DISTANCE
You are right a other thing is that the material get pressed very hard between two metal sides. it make the pad insulate
I think he just used a bad pad, My 3700K with the IC thermal pad and an NH-d15s doesnt go above 70c on all cores
@Phi6er good catch buddy LMFAO...
Jay... that is silicon pad... you need a graphite pad... which is what linus used.
yea, this isn't designed for heat transfer, this is designed to adhere a heatsink to....the graphite would perform worlds better (3x better W/mK)
but graphite pad only works for cpu right? it is bad for gpu right?
Don't see any reason why that would be the case, it just transfers heat.
i think i read some ppl say because it conducts electricity or something. i dont recall too much of it tho.
Yes he knows that’s what he said in the video.
Anyone else notice how at 2:54 the pubg shortcut is named "Fortnite Hi-Res"... 😂😂
James Murray LMAO, all the thumbnails actually lol.
Other shortcuts are funny as well.

MeatNinja compared to what?
Gold leaf as a thermal transfer!
Damn that's a good idea :O Going to patent it and become a billionaire, thanx! :D
you cant afford gold, and even cant afford to patent it. and gold is conductive. :D
rlund3
That's stupid since silver conducts heat way better than gold.
its for the rich people u know they dont care as long as its expensive and something to show off with
good luck not tearing it when you mount the cooler
Jay, you fool. Everyone knows Colgate has superior thermals. For shame!
but menthol toothpaste would do best with it's coooooling taste.
But the crystals add a burst of flavor your CPU will never forget.
jay keeps toothpaste in his kitchen?
I bet you used some Ram Cooling Pads with like 1-2W / mk.
Like you said they just cant transfer the Heat fast enough.
Maybe repeat the Test with something like the Arctic Cooling Thermal Pad (6w/mk),
or one of the the Alphacool Eisschicht thermal pads (11-17W/mK).
the ic graphit ones should have worked too
Thermal pads are great at dissipating smaller amounts of heat, such as that from VRM's. They do get hot, but it happens slowly. You could not keep a computer running without CPU cooling, but without the VRM's cooled, the computer would stay on for quite a while. While thermal pads aren't as conductive as thermal paste, they do better than just plain air, so they are great for filling space, to provide some sort of contact with a cooler if they wouldn't already, as well as I would imagine, decrease, or better disperse the force exerted on the VRM's as to not cause damage.
In short, traditional thermal pads do work, but they don't work as fast, so only use them on slower heating items.
Thermal pads do make sense in GPU blocks if you consider them as spacers. It would be very costly I imagine to design a cooling block that is correctly spaced for all the chips on the card and it is much easier to use an X thickness pad to achieve contact. Another problem is that some pastes can short the chip's legs if it runs down (most are so small that it is difficult to push the correct tiny amount needed from the paste tube and even spreafing can make a mess of things). While some memory chips on GPUs tend to run rather hot, those temps are nowhere near enough the GPU's temp without a heatsink (they're probably in the region of 50-60C uncooled which tbh is not a high temp as far as chips go.
I love this series so much
I've used ceramic thermal paste ( some generic stuff for audio components , and Arctic white) to adhere some old zalman ram sinks onto a 6850 with a zalman vf1000 led heatsink "back in the day" ran it like that for a few years and they never came off/ fell off untill I changed the paste....just throwing it out there, I think it actually did better then pads
Try Graphite thermal pads
That is the wrong one, you mean graphene.
And yes it's a lot better then copper.

Next thermal paste on vrms? :P
nah just dip the whole thing in paste just to be sure
nah he'll put the thermal paste on the chokes
Αλέξανδρο ς very very bad idea
put IC Graphite on VRM'S (mobo and gpu ) and ( like jay sad: gpu ) to see if it's better than thermal pads.
Evolution[NL] Graphite is electrically conductive, so that's a bad idea
IC graphite is the one Linus tested. I really want to see gamers nexus test it. They're the only one I expect to get accurate information from.
Nexus owns a 'the'?
Hmm...
YESYESYESYES!
LTT video was fine, but it would be really nice for gn to review it because their tests are really comprehensive
Tomorrow Im going to be testing the pads with different coolers on a r5 1600 and an 8700k for work. I might post a google doc somewhere for it since its public information.
PureBlue okay little man, let's calm down. Go back to the kids table and let the adults talk.
I imagine the pads are meant to make sure there is some connection between the VRMs and the cooler. Any sort of warping could cause a gap to form between the heatsink and the component. Also, since there are multiple memory chips being cooled, it is difficult to ensure proper contact with each and every chip.
Seems like goldleaf would be ideal for this sort of application.
Berserkasaurus Rex my exact thoughts! They really need to do this
Gold isn't all that good at thermal conductivity and is also electrically conductive. The only advantage gold would have is that it wouldn't corrode. Gold leaf would also be very difficult to apply without getting it everywhere.
@@LordMoebius Gold leaf sticks in place pretty well, in my experience. It's certainly less messy than paste, which seems to be the main issue with thermal paste. It's also easy to apply. Just put a little pressure on your sizing, and the gold leaf will adhere just fine.
Not sure why you think Gold isn't a good thermal conductor, it's one of the best metals for thermal conductivity. In fact, aside from some odd alloys, only Silver and Copper are better thermal conductors, but while both can also be used in a leaf application, they are thicker and will corrode, unlike Gold. The only thing better than those three is Diamond, which obviously wouldn't be applicable here without some serious technological development.
@@berserkasaurusrex4233 gold leaf has a tendency to flake during the application process especially when applying it on an intricate or small surface and you also need to use adhesive to hold it in place. So pretty sure it wouldn't be the best for thermal conductivity. And yea silver and copper are better conductors at a cheaper price point compared to gold. The only advantage you'd get is that gold wouldn't corrode but it's sorta irrelevant in this context so you're just paying for a material that performs worse than cheaper materials.
Plus gold leaf would have the same problem, it will not be able to flow into those microscopic valleys.
Guess you can use non-conductive thermal paste on VRM and memory?

LOVE these fun videos - my all time favorite so far was the beer coolant from a few months ago - laughed for days
Amazing content!
I wished he had added CPU thermal paste to both sides of the thermal pad and tested to see what that does, would have been VERY interesting...
3:03 Really appreciate the zoom
I am glad you did this. I have an old Dell I took apart to fix the fan and because I plan to change the CPU I never cleaned or changed the paste. I just threw it back together and the core temp is always 40c.
If it blocks heat transfer, perhaps it's to block heat from reaching certain areas of a component?
4:46 I took apart my two PS2 Slims and found plastic on the thermal pads. Taking them apart is easy and I recommend any other PS2 owners check their system!
Jayz, Please make a water cooling system where one tube is connected to a water tap and then the outflowing tube from block is flowing into the sink so there is no loop and water is never heating up! I've never seen it done and haven't found anyone doing it, would be cool to see cold tap water cool a cpu!
There might be a reason its not done.
And the reason might be that theres so many that dont have acces to clean water, so it would be quiet hypocritical to do.
But thats just my opinion.
I'm mainly talking about the big youtubers such as Linus, Bitwit and such. Sorry if I sounded bad in anyway, didn't mean it!
dont apologize ....its a cool idea! he should try it
I really get the idea, but honestly it is terrible. For starters it will get costly quick and is ridiculously wastefull. Tapwater isnt free and running a faucet whenever your pc is on will get expensive.
PLS ADD BIG PACET CPU COLER SO I CAN SEND A EMAIL
Jay I love your channel and Linus because you both do the weird things no-one else does, but you take it to another level
Amazing video Jay!
Honestly, I believe I speak for more than just myself when I say that if you tried to de-lid the 8700K (because of it intense heat levels) and tried to cool it, and also make it a "How to", people would be very interested!
Like I myself want to build my system with an 8700K, and I'm using a custom cooler from EK, and different Thermal paste, but, let's be honest, it's an area heater.
Or just grab a Ryzen 7 and you won't have problems like this.
@@nonci6 oh no problem with heat huh? lol
@@taylonjudd923 AMD re-did their manufacturing process and their CPUs don't heat uo as much as before like their FX series CPUs.
Hey Jay, I’ve got a dumb idea/suggestion for a video. It more of a curious experiment.
Here it is:
Delidding a CPU to replace the TIM between the IHS and the die with a graphite thermal pad. 🤷🏽♂️
I wouldn’t have known about the pads if you didn’t make the video. And can’t wait to see the cpu pads in action. It’s doesn’t matter who made the video first without you making the video then where’s my excitement in my life. Thanks jay.
JayztwoPUMPING OUT VIDEOS! Keep it up!!
"never gonna see this kind of load, especially playing games" - Someone forgot to play Cities Skylines at 200k+ population ;P
Designed for those cold winter days. Your CPU deserves a blanket sometimes.
Thanks Jay! Newbie question here, aren't you supposed to use paste between the two surfaces of the pad for actual heat transfer? I'm 49 and new to this next 30 year career.
I wonder how this would compare to a mica insulator with paste on each side? I've been using thermal pads on things such as transistors and IC's for the last couple years, but this makes me wonder if the old mica insulators and paste are better. It's a bummer because the pads are so much faster and cleaner to work with.
I bought one of those ic diamonds thermal pad and my temps increased by 10C at idle.
Damn my cpu went opposite lol. Haha my experience was better than yours!
"I'm gonna apply this with my finger."
Oh god its The Verge all over again
This is very informative but i was wondering have you tried high temp rtv silicone i would like to see the results of that. Thanks
Thank you for a very informative video! Is it possible to apply thermal paste on a gpu in stead of using the thermal pad? I'm asking as I accidentally screwed up my pad on the gpu on my old laptop, so I've put on some paste to keep it cool.
Can you recommend me a non electrical conductive thermal paste for a laptop cpu and gpu?
KPx High Performance Thermal Compound 10G
they definitely make sense on ram and vrms because they produce low heat.The pad will not be a bottleneck when it has to transfer like 5 watts of heat
Also because they're electrically insulating. You get some thermal transfer without risking shorts when in close proximity to 100+ Amps. Thermal pads are rated in terms of watts/area and they're a fraction as efficient as thermal paste. If you had a 3ft square heatspreader, then a big thermal pad would be able to transfer all that heat. A pad that small is probably only rated to transfer a few watts of heat, not the 300 watts or so from an overclocked 6 core.
Allison Pell 100Amps? Are u sure what u saying? Isnt that "100 A"? Maybe im missing something but... U got like i limit of 12 A in the wall, or it will cut out the power...
Gaspar Silva
you don't understand electricity at all my friend
amps times volts is watts. if you are pulling 100 amps at 1 volt, then you're drawing 100 watts from your power supply. your power supply manages how to pull the volts and amps so that you're not drawing too much power.
if you have two electrodes and there's a hundred volt potential between them, you aren't drawing power because there aren't any amps (no electricity is flowing). if you link the two electrodes, current will pass, meaning amps will start existing. the voltage will drop, depending on the resistance of your wire. if your wire has a high resistance, you won't draw as much as if it didn't resist at all (a short circuit). in a short circuit, you have no electrical potential (there are no longer two potentials because there is no two distinct electrodes) but you have a high current, meaning a shit ton of electrons are passing through your wire. this heats it up (pretty much because of friction) and probably melts it.
I'm dubious that there are 100 amps going through a PCB because if you want to have more amps going through a wire, you need a fatter wire. welding wires use twelve amps and they can easily be a centimeter in diameter (welding is short-circuiting metal to heat it up to the point where it melts).
VRMs may pull out about 60W of heat, but the heat is spread across a way bigger area than on a CPU/GPU.
oh, and VRMs aint flat, there are solderings etc arount it which also get contacted.
and since most thermal pads are non-conductive, you can't short out a FET and get 12V into the CPU.
under LN2 you see way more heat output, but since the CPU/GPU is sub-0, most parts of the Board around it are frozen however so heatsinks usually just heat up the Board, cuz they are contacting something which is not at - 50°C or smth.
Hi Jay if thermal pads are so bad on CPUs how good would TIM be on VRMs ?
Thanks for the video. I am only an amateur builder, but I noticed that the thermal pad has different colors on either side. Is it possible that you placed the pad with the wrong side up?
ic Graphite. ever tested Alumium foil ? should work better then nothing
Thermal pads are used on VRMs, memory chips and such for a couple reasons:
1) those parts are less prone to heat damage than a CPU itself
2) more importantly: they need to dissipate less power for unit of surface that a CPU so they do not need the highest thermal conductivity
3) thermal pads are solid, while thermal paste is, well, a paste. It's much easier to cut and apply a pad rather than putting say 8 spots of thermal paste on an 8-phase VRM, so they are much more easily applicable than paste and, as said, they do not need maximum performance.
Another point in favour of pads is that they adapt to different thicknesses, like an 8 phase VRM, without problems of not making contact (if they put paste on a slightly lower chip it would not make a good contact while a pad can still touch)
BackInBlack_4896 Good arguments, I would just add two things :
- good paste application is much more difficult than placing a pad
- the cost might be part of the good answer
keep up the awesome work.
Okay so you said the thermal paste is just filling up the peaks and valleys and stuff on the spreader. So would just sanding down and polishing the heatspreader to a perfect mirror finish improve thermals at all?
2:57 Those are some interesting icon names you chose Jay. “I beat Linus” “Fortnite Hi-Res”
Literally did this exact thing in a late video. Didn't go well.
lmfao!!^^
Science Studio have you jay bitwit linus or the any of the sort ever try and find a way to thermal paste vrms and see the temps? Sorry if it comes off as a dumb question and there be a reason as to why that wouldn't at all work. But if not you guys should try!
Science Studio I see what u did there!
you forgot about toothpaste and no thermal interface tho
Haha
Should I trust a pre-installed thermal pad that comes from the factory on the heatsink/fan combo?
Is there a follow up video for this? Would really like to see your take on thermal pads
Late to the party! In engineering we choose thermal pads when you need to close gaps where you do not have control of component tolerances or a wide gap in component height that needs cooling. It’s a lot better than nothing and vary greatly in “thermal resistance”
"old ass game" is the name of the FSX shortcut, love it
I'm sure Jay gets this a lot, but do you ever use the included pre applied thermal paste that's included on aio coolers. Do you always use your own aftermarket paste?
I would be more interested in a test the other way around. Can you use a thermal paste on VRMs or underneath the heatspreader of the RAM etc.? Will it give a better result than a pad and most of importance, will it stay on it's place or will it just spill out?
I've got a strange idea for you, Jay: Install something like Jack Daniels, or Everclear 190 proof in a watercooling setup, lol ;)

You should try gold leaf. It has excellent thermal properties and it is pretty soft, especially 24ct gold. It would take a little experimenting to get the right thickness, and to apply it with zero creases, but it should work well. Ironically, even 24ct gold is cheaper than many of the TIMs out there (gives you a little perspective on how expensive some of these compounds are).
Would love to see a review on thermal grizzley carbonaut.
Interesting. Does this mean we should use thermal paste instead of pads on the gpu rams and vrms?
No, though you could if you want for personal preferences. Thermal solutions carry eg. 1w per square cm surface, at 0.1mm solution thickness, at a temp differential of 10C, or 2W at 20C, linearly. Depending on the surface available for transferring X watts of heat at a predetermined differential, you can use different compounds or methods. A CPU puts out around 10-15 watts of heat per square cm, so you want paste that can transfer eg. 10W/cm2/10C (150W CPU / (10W x 10cm2 surface) x 10C = 15C differential); VRAM and FETs only put out 0.5 - 2W per cm2, so in this case you can use potentially cheaper, easier to handle, less messy and reusable pads that can transfer eg. 1W/cm2/10C (2W FET / 1W x 10C = 20C differential). If conductivity requirements aren't particularly demanding, whether you want the potential benefits from pads or not, the choice is yours.
Obviously, this means you should use toothpaste on your VRMs
since you wanna know when to use thermal compound vs. pads, I'll tell you!
thermal compound/grease is used for components that require quick heat transfer and experience rapid changes in temperature. a CPU can jump 30C in an instant, and that energy needs to move FAST. thermal compound spreads thin enough that there's barely any of it between the IHS and cooler's surfaces, and mostly fills in the gaps to keep air from insulating the heat.
thermal pads are used for components which are slow to heat, such as VRMs -- it takes a long time [relative to CPU temp changes] for the VRM of your GPU to get hot, and the pads are able to transfer the heat over that extended period. pads act like insulators [like in your CPU test] when there's a BIG dump of heat all at once because they need time to move the heat.
thermal PASTE is the same as compound/grease, but it's an adhesive [AKA glue], and would be used for permanently applying a heatsink to a component, such as, for example, a tiny heatsink on a Raspberry Pi, which will probably never need to be replaced or removed in most cases.
How is a piece of conductor not better for this application? I mean instead of the thermal pad, a piece of conductor will conduct better heat.
What if I use kryonaut as the thermal paste between cpu heatsink contact and 6mW/k thermal pad on the heat pipes which go near or touch the back of my laptop?
@@rohitbaviskar7748 you actually run into thermal resistance due to air trapped between them. Thermal paste or pads push out air and ensure maximum surface contact. Even if you have to conductors that are as close to perfectly flat as we could manage, there may be a tiny air gap (you can never have a truly perfectly flat surface) or they might not be aligned to lay perfectly together
@@tejaspadhye I wouldn't use pads *and* paste, that might actually reduce thermal conductivity since you're adding material. But having a pad between a section of heat pipe and the case might help transfer heat a little... Can't hurt to try
@@DoctorX17 I'm not using them together between heatsink and cpu die, but where the heatpipe comes in contact with the case, the case has a copper sheet typo thing attached just above the heatpipe. I'm hesistant and asking you this cuz the pad might melt and leave behind a mess and my laptop's still in warranty
@JayzTwoCents They should probably design a thermal material that comes in like a foil form. You know, it melts when in contact with heat and turn into gel form but returns into soild form when it cools down.
That would be nice.
I have been wondering if lapping the water block and cpu cover to be completely flat would work just as good as graphite pads or thermal paste?
Thermal pads are cleaner and allow for a greater space to be crossed, if you look at some pads on cards they are thicker or thinner for optimal contact with the gpu/heatsink, less metal machining and cleaner. They are also used in testing applications, as in hey lets see if this cpu boots as fast as possible then onto the next. OH AND they work well in situations where something is warmer than expected due to bad silicon or design, like the recent fiasco with evga? sending thermal pads to 1080 buyers.
also helps with unevenness of components
My 8700k does 4,7ghz on all cores with 1.18v. And its not a golden unit or anything. If you apply 1.42v for testing purposes its fine, but you could either try to increase the speed or lower the volts maybe...
i thing that the cpu does that in stock,some motherboards came with mce enable which made all cores hit 4,7 on very high voltages in order to cover all chips,manually tuning is always better.
A dude in a hardware enthusiast Facebook group I'm in got his 8700k running at 5.61GHz@1.34v stable. Absolutely insane silicon lottery winner. He's using an Corsair AiO btw.
Yeah..... I'm not believing that claim...
Russell Sleight Yeah, pic or it didn't happen.
myoriginalname 5,6GHz nope, especially at that Voltage
i would like to know how good is these thermal pads and has anyone used the thermal pads on threadripper ? if soo how did you get it to fit in or what are the size ?
the pad is there to somewhat cool the VRAM but has thermal resistance to prevent the heat coming from the GPU to back draft.
That crunch in the toothpaste isn't the "Whiting Crystals".
Toothpaste is an abrasive. It's microparticles in tasty soap. Basically silicon and soap. It cleans your teeth and whitens your teeth by literally scrubbing and scraping them.
The whitening crystals (lol) are usually just things like peroxides and light bleaches in crystalline form.
Another idea/experiment: use pencil graphite instead of thermal paste... 🤷🏽♂️
Needed to renew my VPN service and switched to Nord from PIA with Jay's code. Been using it for a few weeks and so far I am loving it more than PIA.
Thank you good to know
Folk: I use regular thermal paste to help cool down my CPU, what do you use?
Me: It's a little complicated...
Never liked the pads as thermal interface and often wondered how effective they really are. Whenever a better option is avail i will go that route.
Scott Jamerson the graphite pad from diamond-cooling or wtfe the company name is seems to be promising
I saw that actually. :)
Indeed looks promising. Like Jay i am looking forward to giving that a try.
Dual Scimitars the problem is that the graphite is conductive haha.
Thermal pads are used on VRMs and other stuff because you don't have a giant flat cooler on a flat component to cool it, you need to transfer heat over a 0.5mm or sometimes even bigger gap and neither of the surfaces are flat for the whole surface. They are not meant for 300w CPUs and aren't good enough for that. By the way the EK pads are especially crappy, there are way better options out there. Yes that IC graphine thingy but besides that there are more "normal" better pads out there too
300 watt cpu? XD
@JayzTwoCents That type of thermal pad isn't for what you think. its meant to go on things like ram to spread heat through the chips in the case of vrm and normal ram. This is not for cooling but when the silicon heats and cools when in use so a hot spot could cause that part to expand while the rest is still stiff causing the sodder and silicon to warp damaging connections in sodder. This is the same for the case with heat spreaders on normal ram sticks.
Thanks for the video. Regarding your question about the idea of thermal pad and how it works, I should say that when heat (or any other things like sound, light, motion, electromagnetic waves, etc) conducted through a medium everything depends on the conductance capacity of that medium and as long as the medium is homogeneous (no abrupt change in the material) everything is fine. However, when heat reach to an abrupt change like passing from one medium to another one the challenge happens. Exactly in the junction you have an abrupt homogeneity which means that the conductance capacity changes abruptly because of two reasons: first is that the junction surface is not microscopically perfectly flat and there will be thin layer of air there (air is a heat isolator) the second reason is the difference between heat conductance capacity of the two medium (the more difference the worst the case). To envision it assume that you are on the roof of a building and want to go to the nearby building if the height of two buildings are the same (conductance capacity) then you can easily go on the roof of the nearby building but if the heights are different you cannot go and you need a ladder (conductance matching) which helps you to smoothly pass the heterogeneous junction. You can model the microscopic air-gap with the space between two buildings. This is what thermal paste or pad plays in the junction, providing a ladder for the heat to easily pass the junction for both removing the microscopic air-gap and conductance difference. The specification that the thermal conductance should have is that it should have a conductance capacity that matches to both mediums.
2:54 awesome shortcut names..
I like the one above Fortnite Hi-Res
use bacon as a thermal pad
have you tried running ether or kerosene or other volatile chemicals in a water cooling loop?
@JayzTwoCents , Might be miss-wrote the timeframe , 4:51 should be Thermal Pad , and 7.21 Should be Thermal Paste . Take a look at.
Anyway , Can i use both Paste and Pad , Like putting paste on both sides of pad ? Would it make any improvement than worst result ?
The thing about thermal pads is: with a cpu they get saturated with heat and they can't transfer anymore heat, but on something like vrm or ram they have a lot more area to transfer the very little heat (in comparison to a cpu) and don't get saturated. It's like spilling water and cleaning up with a sponge and then seeing a flooded house and trying to clean it up with the same sponge

How about extreme polishing on both the water block and the heat spreader on the CPU? Smoother, super flat surface should help transfer the heat more efficiently without the need for paste. DO IT! Please :)
do you have millions to do it ?
No ?
That's why we can't.
When you polish something, you're just making thinner scratch/dents in the material.
For a PERFECTLY flat surface, you need an ultra-precise machine, with an ultra-expensive cutting tool. It can easily cost hundreds of thousands of bucks.
Hey Jay how you thought about useing different brand grease's for ball joints as termal grease.??
Jay, did you ever try the thermal compound called Indigo Xtreme? Its kinda of like solder, in that when you install it you have to purposefully run something like OCCT or Prime to heat up to max for 10 secs, then turn the pumps on to solidify the material. Suppose to be a few C drop from the paste, i also found it easier to clean up but its more expensive.
6:33 OMG USE BACON!
Well look by Linus, he has a nice working Thermal Pad
Luzifer Senpai ルシファー せんぱい but as far as i understand it, what linus tried is a special different thermal pad
His thermal pad was also way thinner ;-)
linus used a thermal pad designed to replace thermal paste
this one is just a thermal pad
He used IC graphite, which is made to replace the thermal paste. These regular thermal pads Jay's using are for lighter heat loads
The IC graphite pads are also conductive, so they can't be used on RAM modules, etc either.
Does the flavor of the toothpaste matter?? Would ice mint cool better than cool mint or bubblegum?
Hey, could you soder a tube on top of cpu, fill it with water. So, heat will be absorbed by water at bottom (from cpu) and let it evaporate from top?
Thermal pad = Thermal blanket.
He is using the wrong ones, because he could not get the graphene pads.
Don't get fooled with the word "Thermal pad"
The pads are there to add thickness and allow for contact where there would otherwise be an air gap. This was painful to watch. The pads conduct much better than air and that's what matters.
I have an old Asus laptop with a chipset that runs ridiculously hot. There is barely enough space to put a small heatsink on it but the only way would be with a thermal pad to hold it in place. Could I get your opinion on using a thermal pad on it? Should I just leave it as is? Thanks!
Hello, guy who commented two months ago. Get some thermal adhesive instead of a thermal pad if you're looking to attach a heatsink like that.
Yes and no.
Because air keep heat, you need to fill these gaps at a molecular level, that's why we add thermal paste. In theory, you only need a few µm thick layer, even of cheap thermal paste, but of coure we can't do that, so we put a layer thin enough at our scale of better thermal paste.
The best would be :
- a perfectly flat CPU and heatsink (impossible or ultra expensive)
- put the CPU and the part of the heatsink that touch it under vacuum, and the fans out of the PC case like you normally do (best solution, not really expensive, but hard to put it on a PC)
I ways wondered about using a high end sil pad for a CPU. Some of the comercial sil pads are pretty extreme and have some really strong adhesive
learned something new,makes sense too
