Yes exactly, however when you're using liquid metal or an electrically conductive thermal paste (like the Arctic Silver 5) you have to make sure the compound doesn't leak onto the motherboard when screwing back the heatsink. Most thermal compounds like the Arctic MX-4 or Noctua NT-H1 however are not conductive so this isn't a problem in most cases

Chances are barely anybody will encounter this but there are super thick thermal pastes, which do yield worse temperatures when applied too thick! Specifically for instance the Phobya Nanogrease. In my tests the single best thermal paste outside of liquid metal and that stuff is so so thick, that you can't even use the blop method. However, when applied correctly awesome results and that explains (to me) why there's so much deviation between tests concerning this paste.

Beware of applying too much liquid metal though

I accidentally put too much thermal paste on my acer nitro 5 and for the first week it was perfect but after it started getting more and more worse ending actually more worse than old thermal paste. It seems to me that at the beginning it is good because the paste is still in a condition like from the "packaging", but after use it starts to harden slightly, which causes hardening on the surface of the processor and the heat sink, and there is still a "packaging" consistency in between, which blocks the heat flow and keeps the heat between the heat sink and the processor (and its MORE LIKELY problem of processors without IHS like in laptops)

I spread a very thin smooth amount onto the cooler, then apply a small(rice) to medium(pea size) to the cpu. This works perfect everytime, good even coverage, little to no overflow, and pretty much dummy proof method.

I always spread the thermal paste evenly over the *entire area* of the top of the CPU case. Otherwise I would not know whether the "squishing" caused by the pressure of the heat sink has been adequate to reach the edges of the CPU case. Also I believe that the layer of thermal paste should be *as thin as possible* . It is only there to fill the microscopic roughness between molecules of the metal surfaces. The thermal conductivity of thermal paste would be *much inferior* to that of the metal itself.

I think the issue is more mounting pressure. Paste must fill air gaps, so if you've got poor pressure between your CPU and the cooler, then it's not going to cool well, because then the paste will be thick regardless and act as more of a barrier rather than a conductor for the microscopic air gaps that it's meant to fill.

Think about it. He added more and more paste until eventually there was no further benefit. And that was achieved with normal paste. So how can using ceramic paste be any better? Even if the ceramic paste has better thermal conductivity, firstly he demonstrated you don't need it, second the elements involved in dissipating the heat is not just limited to the paste, it is also dependent on the design of the heatsink and performance of the fan attached to the heatsink. And once the chip is operating consistently within its normal operating temperature range, what benefit is there in trying to reduce the temperature further? The chip doesn't become faster because you reduce its temperature. It may give more room for overclocking, if that's the way you want to go. The temperature does affect the longevity of the chip, and chips that run too hot will have a shorter life but that shouldn't normally be an issue.

I always put a little bit on, but then I spread it out with a small piece of plastic (an old bank card) to make sure every single corner is covered. Manny applications leave some space left at the corners. I'm amazed that so few people do this and just use the heatsink to spread the compound.

@@TheAechBomb That would be ideal. You only need to replace the last bit of air by paste, not more. The parts should touch each other, and where they don't, a bit of paste is better than air...

Yes, there will always be small imperfections or honing/machining marks and the paste fills those imperfections with something thermally conductive. I spread a thin layer across the entire surface then tighten down the cooler until I don't get any movement of the cooler with moderate side pressure.

Test after test shows that excess paste just gets squeezed out. The "thermal insulator" thing only comes into play if you have insufficient clamping force on the heatsink mechanism.

aaayyyy thanks bro! very helpful😊

I always do what the Noctua manual says, one pea in the middle, 4 tiny peas in each corner with some offset (like a 5 on a die).

Use power fulll fan with thermal syastems and heat shrink try it your old pc will blow out by overclocking

normally you would spread out the paste over the area manually before applying the heatsink. This gives 100% coverage and thickness is only to fill the roughness in the 2 metal surfaces. Without paste almost no contact area would result due to the hard and unflexible surfaces. So very very tiny layer is needed. Paste is not as good conductor of heat as metal and should be as thin as possible and ideally just to fill the "no contact" spaces between the 2 metal surfaces.

Thank you! Great experiment to show all the computer professionals that more paste doesn’t automatically mean it will serve as a thermal blanket and have temps shoot through the roof.

I started to use cross pattern...theres so much coverage with it i love it

Been building PC's for years, even professionally for many of those, and always found that adding a little extra (and I do mean a little, not the entire tube, like here) for piece of mind was never a bad move... To this end, I've always liked the X application style, as sometimes a dot in the middle just doesn't spread to all the corners...

The X is definitely my favorite method, since an X will naturally expand into a square when it gets pressed down by the CPU cooler.

The corners don't get as hot so that's not an issue.. The only thing thermal does is flatten the surface.

Can you do the same test but instead of just putting the cpu cooler on, use your finger to spread the thermal paste all over the IHS. I think the smallest amout of paste may do pretty well with the finger spread method.

You are exactly right, and it's provable. The thinnest layer of thermal paste that you can evenly spread over the surface, is the CORRECT amount. Unless you leave it in a blob like this guy did. I wouldn't post videos if I had his lack of knowledge and experience. I get his point that there's a such thing as too little or too much, but he used too much for the layer thickness in EVERY example.

Thanks quick and too the point

Your video just made me feel a lot better about the last time I had to remove the heat sink from the GPU in my old graphics card. I didn't quite "glob" it like that, but I definitely used a bit too much.

Seems like it depends on the cpu currently Intel is a monolethic die so a center blob is fine even for AMD it should be fine as it's better than nothing but an X pattern for Ryzen is better due to the chiplet design

I really like the complete paste method, apply a thin layer all over the IHS using a spreader and then there is no part of the IHS that has a gap to to the cold plate of the cooler. This is how you can get consistency each time without uneven pumping/squeezing out of thermal paste..

That's the right way to apply thermal compound. But it takes some effort so no one's going to do that. Because they're all a bunch of lazy bastards.

It's never too much. I tested it myself, the excess is just squeezed out when you tighten the screws. I had max 1C temp difference between normal amount of paste and excessive amount of paste.

Define "never too much". I would say too much is the point at which adding more paste achieves no worthwhile benefit. And he demonstrated that point in the video. So yes, there is a point where too much paste can be added.

I've seen a local pro applying paste, and it was a huge amount. Seems like he knew there's never too much.

i tried the medium size dot for an aio. lets just say, temps went close to 90c under full load and only spread in the middle. spreading the paste covering the cpu kept the heat down around 70c under full load.

You are lying or something happened during your tests. It's just impossible to the application style make that huge difference, even using strange things like toothpast dont produce a huge difference like that.

i made a 0.5mm sheet with a small additional blob in the middle the last time i did it. it sure was way too much and squeesed a ring around the socket but i at least could be sure that it was everywhere and not just on one side or with nothing pockets.

It's just the recommendation I needed! Thanks, KZread!

I'm sure this video will find out the same conclusion the rest I've seen did. There's never too much, only too little. The performance loss on using too much is negligible but the loss from too little is overwhelming.

For me the less the better. I used too much and my temperatures went up. Small dot, spread it evenly, instal radiator and forget for a year.

I realized that my liquid cooler is a crap, my CPU reaches 80°C on stress test, and it's one month old

I tested the paste on the Ryzen 6350.At idle, its temperature is 17-19 Celsius.I used Cooler Mastergel Maker paste.The temperature has been the same for more than 1 year.With Artic pastes and the like, processor temperatures were once or twice as high.There is a huge difference in quality between the traps.Example paste 2g for 4-6-7 dollars it can’t have the same quality as 2g paste for about $ 19.Cheap pastes are also all fake they are not original and they also suck.So when using a quality paste, spread is not very important but it should not be too small and not too large. The paste is designed to compensate for microscopically small irregularities in the refrigerator therefore it must be lubricated very thinly.If the paste is too thick a layer then the temperature is much higher.

Thanks you I feel so much better now

I would never put thermal paste like that. One of the things I most enjoy while building or cleaning a desktop PC is to manually spread the paste all over the CPU until it is evenly distributed in a thin layer (I use CoolerMaster's accessory that comes with the thermal paste to do that). If you don't do that, you are letting the heatsink have all of the fun.

Great video...thanks.

As long as your paste isn't conductive and your cooler has enough pressure to make good contact, then "too much" shouldn't matter. If you are using conductive thermal compound, then getting any squeezed out the sides could be a disaster. Just something to keep in mind if any of you out there decide to go the liquid metal route

Realistically the best method is to use a spreader to make sure you get full coverage for the best heat transfer.

Very!..........useful and reassuring

great to know this, thanks!
