Hello,
I have a Palit GTX 650Ti OC 1GB and I was wondering what is the acceptable temperature for this graphics card?
I have a small case, and the graphics card is quiet close to the bottom of it - about 5cm.
I've been playing WoW for 5,6 hours and the temperature is between 70C- 73C. Should I be worried and look into buying a larger case or something, or is this temperature acceptable after a heavy load?
