Hey there, I've been playing crysis 3 a lot lately and it usually run's my GPU temp around 65-70 degree's ( MSI GeForce GTX 770 4GB TWIN FROZR ) I know the card is suppose to run up to 80 degree's no problem but I was just wondering if I played at these higher temps for 3-5 hours at a time. Would that be to much stress in terms of heat on the GPU ?? I have the Corsair 230T Windowed-BLUE ATX Mid Tower Case> I have just the stock fans in it and I was looking to add more. I was just wondering if people have preference over tower fans ? if so what are some good ones and why ?
