I've been using this cooling system for... well about two years now, and have never had any issues...until today. I was running the guild wars 2 beta test, had been doing so for a few hours, and all of a sudden my machine shut itself down. I rebooted, and again it shut down right away. I assumed it was over-heating so I left it alone for a while and started it up, went into the bios and looked up the CPU temp. From start up, it went from 35c quickly climbing over 72c, while simply idling in the bios... I cant even load windows without it over-heating and crashing instantly, any ideas?
