I have the single fan 750ti, I was playing Bioshock:infinite on high, I alt tabbed, look at the temperature, and it was 60c-70c I was Instantly scared! I took off my side panel, (Touched the case to discharge) and touched the bottom of my card, It was finger burning hot, The Fan for my Card is located right beneath the wall to PSU. (300w psu) SO there is about 4in of space between the fan and the wall, Also below my GPU is the Cpu fan, and another external fan that blows outwards. IS THIS TOO HOT? Will my card not last long running like this heavy duty ?
