i am having some big time stablitiy issues with my system. but first thing is first, how hot does my 6800GT have to be , to render my system frozen or w/e , reboot, etc. i dont know whats causing my system to reboot, im guessing a heat issue, and i dont know what sensor program to beleive. i have a thermal sensor attached to my xp-120, is that correct? i seen my gpu get up to 72C, reported by nTUNE monitor, and cpu is only getting as high as 38C, any suggestions?
