I own a PC with a GTX 660 and an i7 3770k, it can run games well. However, I recently purchased Far Cry 3 and set the settings to medium with Vsync locked at 60FPS, the GTX 660 hits about 65 degrees MAX whilst playing this game, should I be worried? Also, is it dangerous to turn your card's fan speed up to 75 percent? That's the max I can turn it up to with Thunder Master by Palit - yes, I'm using software called "Thunder Master" (it came with my PC) to look at my GPU temps. Thanks.
