Hot Spot temperature down from ~ 102°C to ~ 75°C on my gold old RX 6800xt just by deshrouding and putting a huge chunk of thermal pad between board and backplate? (alien.top)

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 am using with my RX 6800 a different thermal paste: "GELID GC-Extreme" I read that this one has good level of viscosity. (I have a Waterblock on mine).

But sometimes I'm tempted in getting a good modern thermal pad and give it a shot to cover more GPU area.
