Best thermal apply method for GPU?

SumTingW0ng · Aug 14, 2017

So I'm planning to clean my almost full dusty ASUS Strix GTX 970 this week, and I have Arctic MX-4 Thermal Compound tube lay around on my other desk . I know I have to re-apply thermal compound if you are going to re-assembly the graphics card, but I don't know the best thermal apply method for the GPU. Should I spread evenly or apply a small rice peas in the center of the chip?

Check https://www.youtube.com/watch?v=AOp2zS-SB0o
Or similar.

Dont spread it, just put a rice sized blob in the middle of the gpu, let the heatsink spread it when you reattach.

So in that video, re-apply thermal on GPU increase 2 - 4C max temp over manufacturer pre-apply thermal compound. I thought re-apply thermal compound should have the same result or a little better than manufacturer pre-apply thermal, not getting worse.

Oh okay, thanks for your input.

Apparently, not.

Yes. I suggest leaving it as it is.

Yeah, I wish my GPU PCB were not covered in dust, and since mine does, I have to re-assembly it to clean it up. In addition, the heatsink outside and inside were covered in dust too.

You can use compressed air to clean it.

SumTingW0ng · Aug 15, 2017

alexoiu :

But sometimes dust stuck in small hole that compressed air can't get into.

alexoiu · Aug 15, 2017

It would not affect the performance.

alexoiu :

Okay, I will try that first before re-assembly my GPU. But one thing I'm glad is that my GPU doesn't have thermal pad, so that one thing does not need to worry.

RobCrezz :

I did your method you suggested, and found my max load temp drop to 2C min to 3C max.

Yep that sounds about right.
