The card essentially begins to throttle its clocks at 75 ish degrees ( temp limit is 85). It is a Sapphire Nitro RX 580 + OC edition. I repasted it and it worked fine for a while ( no throttle and the temps were in the 70s, then i undervolted and it worked fine for a while (same thing). I have already reseated the card and reinstalled windows/ drivers multiple times. At this point i assume some component besides the core must be overheating so i will replace the thermal pads: what thickness pads should i use and is there some other solution possible besides this?
