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

      I have the same card. It goes up to 110 °C at default settings but never reaches 90 °C when undervolted to 1050 mV.

      I’m thinking of replacing the thermal paste with Honeywell PTM 7950 or Upsiren PCM-1. How did you disassemble it? Can you share some insights with me about that?

        AFAIR you unscrew all screws on the backside of the card, that should lose the complete heatsink/shroud construction. From there, you’ll find more screws that connects the shroud to the heatsink.
