I think I fixed mine. Started playing the game 2 days ago with crashes every 15-20 minutes. As stated, most games previous ran temps around 62c-70c. This game runs well above that causing it crash. I have a highly ventable case I normally close up to keep dust out, but I opened them up this morning and only had 1 crash in 8 hours of play. I also changed the fan curve to put the fan up to 75% when its over 70.

If anyone doesnt know how, the following utilities can help check for heat problems and help set your fan speed to kick on much faster:

CPUID hwmonitor: I use this as it tracks the current and highest temp of the graphics card, CPU, HD, and other. Since it saves the highest temp, its easy to see if its heat causing the crash. Anywhere north of 75c is too hot. Open it, play the game for 15 minutes, alt tab and check Max column. Simple.

EVGA Precision X: Easiest app to set your fan speed curves or just manually crank your fan to max.
