Hi, a couple of months ago I am having a problem with my ASrock Rx 570 graphics card. What happens is that I did a maintenance to this, the first time I did it. I changed only the thermal paste. After that maintenance I started to see that the temperatures instead of improving only got worse and even the screen went black and the fans at 100%.
I tried several possible solutions, first an undervolt that at first seemed to solve the problem but then again raised a lot of temperature. I tried to change the thermal pads for new ones and there was no effect either.
After some research I think it is the thermal paste I used. I used one called pastermax g60 that I used with my processor and never had a problem. Now I investigated it a little better and I saw that it has a thermal conductivity of 3.17 W/m-k. I think this conductivity is very low for the gpu which raises a lot of temperature compared to the gpu, but I'm not sure anyway. Can someone help me?

Have you checked the GPU die to heatsink contact area to ensure full coverage?

Some cards use a phase change thermal pad instead of paste for the interface material. In such usage, thermal paste does not provide enough thickness to bridge between die and heatsink contact plate.

Have you contacted ASRock support concerning your RX 570 graphics card?

I checked and it looks like yes, they do make good contact. When I first opened it, it had thermal paste, not thermal pads. I have already contacted amd, I am waiting for a response, but I have not yet done so with asrock, I would have to check.
