As long as I had my XFX 6800xt, I had some temperature problems. The GPU temperature went up to 80°C and the hot spot temperature usually stood at 105°C, but occasionally went up to 110°C. So the fans were screaming as if they were being slaughtered.

So I removed the shroud, replaced the 90mm fans with 120mm fans, which I had lying around in my “tech box” and which are now hanging on the heatsink through zip-ties. And a 100x100 3mm thick thermal pad between the backplate and the back of the board.

Result: Furmark (as an extreme example) just manages to bring the respective temperatures to 57°C GPU temperature or 75°C hot spot temperature.

I would never have thought that an investment of €8 could make such a difference

    Pretty annoying how AMD GPUs are plagued with bad core to hotspot deltas. I got the Red Devil and still have 30 C delta 🥲. I do plan to open and play around with it. For now I just increase the fans. I do have pretty good silicon. Can do 2.5 GHz on the core and 2150 MHz on mem (fast timing) without increasing power limits and lowering voltage down to 1020mV. Usually get around 7-10% more fps.
