No, the rebooting Mac problem isn't fan related. It's a graphic setting that I fixed once before, but I've reformatted my boot camp partition and now it's happening again.
Basically what SEEMS to happen is your graphic card gets overloaded, the machine studders/locks up, then you reboot. When I fixed it what would happen is my graphics would lock up for about 2 seconds, then catch up. So there is some problem there that the setting fixes. I'm pretty sure either this thread or BillZBubbas thread had the key to what setting I changed, but for the love of god I can't remember what it was.
I'm experimenting now.
