How does someone get to know thermal paste is a requirement without accidentally seeing how it’s required?
This is like knowing petrol is needed for your new car, then just stopping at some point, referring to the note “Get petrol” and deciding pumping it into every orifice the car has is what that means.
Engine oil? Well, petrol comes from oil! Better fill it up! Air goes in the intake, and we need fuel and air to mix. Throw some in there!
I can’t remember the video but it was some dude from a major computer YouTube channel fillmed himself building a PC. He used a grounding strap that wasn’t grounded and did all this crazy crap. They ended up taking it down fairly quick but not before everyone made fun of it. I think even he used thermal paste though.
It was the verge lol
I saw another video where the famous YouTuber censored out the thermal paste pattern sort of as a joke but sort of genuinely heading off comments disagreeing with how he put it on.
Reminds me of this: Synthetic Krabby Patty from SpongeBob, with gray goop in it
Oops all thermal paste!
Me when I have to use anti seize in the shop
At that point it’s just thermal paste with slight hints of computer.
Oh no, oh no no no no no.
Optimal thermal paste thickness (bond-line thickness) is critical for heat dissipation. The layer should be thin, ideally between 25 µm and 50 µm, which is roughly the thickness of two sheets of standard paper. The paste’s sole purpose is to fill microscopic air pockets between the metal surfaces for better thermal conduction. Source, I spent 6 months in a laboratory experimenting with and producing thermal pastes and insulators. I spent days cutting and cleaning copper squares, applying the experimental pastes, and testing thermal conductivity via the application of Fourier’s Law of heat conduction.
Q = kA(Δ T/Δ X)
Where Q is heat flow, A is the cross-sectional area, and Δ x is the paste’s thickness.
That’s way more paste than you need for 50 µm application.
Drops Mic
I can’t tell if this is satire. If not, you say it doesn’t hurt to use too much, but I would say that a company would want to save all the money wasted on applying 20x the required amount…
The only thing too much thermal paste does is leave a mess, but you might need thermal pads on VRMs for better contact
Too much thermal grease is a barrier to heat, because it should only displace the air (a potent thermal insulator) between uneven surfaces. Oil would be better, but that runs away.
Rice corn or spaghetti method displaces the air on putting the cooler on.
I’m not familiar with those methods and “rice corn or spaghetti” makes me think you boil the the paste first
Wouldn’t sharing heat from a processor directly with other chips be a bad thing? Always imagined you could fry the little chips by the CPU or GPU or whatever you’re cooling
The chips are going to have a similar tolerance to heat. They’re all silicon and the fundamentals of how they work are the same. So if may be making a chip hotter than it normally would get, but still within its operational limits it’ll still work fine.
Though there is the argument that if the chip otherwise wouldn’t get that hot that you’re subjecting it to more thermal stress by subjecting it to wider temperature swings than it would otherwise experience. However, I wouldn’t worry too much about that as that’ll take a long time to be a problem.
Is it odd that this is not even close to “bad” I have seen. Hell I have seem things shipped from production with this level of glorp.
Witness me!
Don’t do this
Yeah: Use a paintbrush to cover the whole motherboard instead.
Get a couple cans of spray thermal paste.
Not sure I see a problem here, this all looks intended. I’m not familiar with this device though
Thermal compound has a thermal resistance. It’s better than air, but not as good as metal. The best application is a layer that fills all the air gaps, and no more.
Adding to this… Airgaps is not emphasized enough here. There is a reason why do don’t do closed shapes when applying thermal computer, and why so many system builders have strong opinions on how to apply it.
Personally, I go for an X or a % where the os are actually dots.
Who is saying that is the major consideration here?
Its obvious the major problem here is ustable movement and flexing when those large sink plates are screwed down.
“A dab’ll do ya.”
if they had to put some in their mouth, they should have used mayo instead.
They mayo goes in the computer and I’d like a ham and cheese on rye with extra thermal paste.
They graduated from eating Elmer’s paste to Noctua paste
That’s one expensive transition
The bigger the gob, the better the job!
Loads of goo? I can count on you!
It’s not glue lol.
It’s paste. Which means it’s edible.
Oh well in that case…
I changed my GPU thermal paste 2 days ago. I guess I need to open it again and empty the rest of the tube.
Each of those chips have basically half a container on them, so I’m not sure how anyone got the idea they should use that much.
I paid for the whole container, and by god I’m going to use it!
The industrial containers I had the pleasure of producing and shipping could all be re-sealed for later (industrial) use. Are the options available for commercial use not able to be re-sealed for later use? As long as it’s properly sealed it can be good for 2-5 years.

Back in the very early 2000s a friend on mine that I thought was pretty technical heard me talking about thermal paste and he had never used any. After telling him about the benefits he was excited to get some and use it on his new PC he was building. He came in the next day sad, said it had fried and he thinks it was the paste. I asked how much he put on and his response was “umm, like icing on a cake”. in my head it was even worse the the posted image.

Oof, it’s nice that most thermal paste these days is non-conductive
