Sounds like the CPU fan isn't cooling. Might be bad or going bad. I thought that in the bios there was an auto shut down to prevent the CPU from reaching such high temps. I know there is on the desk top mother boards. On my gigabyte mother board there is a desk top program where you can set fan minimum speed limits for the fans and max temp limits for the cpu. You can also over clock through the program, (Called EASY TUNE). I have mine (CPU) set low 50 degrees max temp. Before I added my additional fans (2x tornando fans, & 3 80mm case fans, 1 5.5 inch slot and 1 HDD, max 32-35 degrees now) my temp went to 58 degrees once during some heavy gaming and a loud warning came through the speakers, lol you would of thought I was having a huge meltdown. I'm sure its a fan problem, the CPU is under clocking to save it.
