In one of my computers, I have this nVidia GeForce 8600GT 512 MB GDDR2. When idling, it stays between 65-75 degrees. during a graphically intensive game for like 5 minutes, the core temperature can reach slightly over 100 degrees Celcius. even after an hour though, it stays at those temperatures. The card in theory should be able to handle temperatures under 105 degrees celcius. I know my temperatures are wayyy above the recommended temperatures, but as long as the temperatures stay below the 105 degree threshold the card can sustain no permanent damage right? Or am I wrong and my GPU is completely dead? And if there is damage, does it affect the performance and FPS in games?
