When I play games on my PC, my gpu gets quite warm. I have one intake fan on the top of my case, which the air from it hits my GPU spot on, and it also helps my CPU a ton, and I have the rear exhaust. But my GPU is hitting around 77°C when I play battlefield 3. I don't want to test it on more demanding games because I'm too scared to damage it. Is that an ok temp? I've read about people with my exact same setup only getting it to 60°C under full load. Also if it helps anyone answer, I have an fx 8350 with the stock cooler on it. Would that also be an underlying cause?
