Sounds like that games stresses the system more than other programs you have. Have you ran Prime95 in standard and torture test to see if your system is stable? Maybe run that game in windowed mode so you keep temp monitoring for the cpu and the gpu in the background. I bet the GPU is running hot and needs more cooling.
