I have an RTX 3080 that was pulled from an HP prebuilt. The core, memory and hotspot temperatures were high so I opened the card up and put new thermal pads and repasted the GPU. The core and hotspot went down significantly but the memory was still high at full load. I undervolted the card and the hotspot and core went down even further but the memory was still the same, around 95-96. I used 1.0mm Gelid thermal pads.
I took the card apart again and checked to make sure the pads were all making good contact and even pressed them with a roller to make sure. Still the core and hotspot are fine and the memory is the same.
At this point I just want to know if it's ok to play games with the memory at a steady 96 degrees. Also do you think 1.0mm pads are too thick or thin for the memory and that's could be why the temps are still high?
