Question Thermal Pads In General (and Vega64)

[An Arable Hill]

I'm pulling apart my GPU to replace the paste and thermal pads. I researched the thickness(es) I'd need for my card (1mm and a 1.5mm), but I was curious about the width. It looks like I can buy it in sheets or squares of different widths. I was thinking I would buy sheets and cut to fit, but figured I'd ask for advice as maybe there's go to size and also if you happen to know about the Vega 64 in particular.

I am sorry to do this to you, but:

I think you just buy a sheet and cut to fit. Never done it myself, but others on this forum have and seemed happy with the results.

I feel you should have asked this in your other thread that you already had started: https://forums.anandtech.com/threads/reference-vega64-temps-jumped-overnight.2595323/

I do it all the time.
I only buy sheets, its far more economical that way.

The sweet spot in thermal conductivity for the pads is ~ 12.6-12.8 W/mK.
Look for sheets that are around there if your repadding a GPU.

I would avoid the 6 W/mK.
I would also avoid the really cheap 12.8 W/mK that is made is China. Its not real 12.8
Avoid going higher, it turns more clay like as the number goes higher.

So yes, in short, look for a real 12.6 -12.8 W/mK and sheet size of one side being no shorter then 60mm

aigomorla's suggestion of ~12 W/mK is solid. On most boards the VRM run WAAAAAY under their max temps. So even cheap thermal pads are probably good enough. Though, 12 W/mK thermal pads sheets are pretty cheap already.

But I will say that going higher does make a difference in some applications. I got fujipoly XR-m (17 W/mK) for the memory on my GTX 1070. I was able to push my memory OC a little bit higher. Definitely not worth the cost, but I like tinkering and pushing my hardware and finding the limit. This doesn't apply to your Vega, though, since the HBM is on the same package as the GPU die.

I concur. Please use your first thread for any additional questions concerning your GPU.
