FAQ: What incorrectly applying thermal paste can do.

post #1 of 23
Thread Starter 
So, I just applied thermal paste incorrectly to do this review, then did it against stock in a 30c room, then in a 22c room, and here is what I found.

Stock after 24 hours of benchmarking:
30c room/86c GPU
22c room/68c GPU

Incorrect after 24 hours of benchmarking:
30c room/94c GPU
22c room/84c GPU

Correct after 24 hours of benchmarking:
30c room/83c
22c room/65c


Sorry about this, it's just a quick thing for people who apply it wrong, and warning them. This took me about 6 days of benching to get these stats, but I lost my copy of office 2010, and have been to lazy to install. I hope you understand the danger of not applying correctly(not really danger, a GPU can do 94c just fine 24/7, trust me ).

Can you please explain how you applied it wrong?
And what made it right?

Sloppy application, not even, missing in some parts, stuff a first timer would mistakenly do. When I did it "right" I applied it even and nice, it dropped my temps almost 4c to apply AS5 over the stock EVGA stuff.

Did you spread it yourself, and using what?

Don't spread paste... a rice grain sized amount in the middle, and clamp your heatsink back on. Simple and zero need for spreading.

That's why I asked him, spreading can cause air bubbles. I used 4 small dots when installing my water block.

I spread it using a razor an made sure there were no bubbles.

That's what I did in my incorrect applying pretty much, it adds much more to spread it with a razor.

I would think you'd need to use the X method or 5 dot method with the massive gpu IHS.

I can't imagine the small rice grain I use on a 32nm Intel chip working well on a Fermi gpu anyways.

Plus I know 4 series heat sinks have direct contact heat pipes, its gonna take more than a rice grain.

Yeah for a GPU, the rice method just isn't enough.
YOu need either lines, several dots or X method.

For the 4xx series, especially the 470 or 480 reference cards, you need a lot more, as the heatsink isn't connected directly around the block, but to the holding shroud, which means the heat-sink isn't that well secured to the GPU.

This^, small uncooked grain of rice and pressure from heatsink does the trick.


On a another note, PLEASE STOP REQUESTING REP AGAIN!! I pmed you a couple times and explain why you shudnt and also the fact that its against the tos.
