I have a MacBook Pro, 15" April 2010 edition, which overheats and then freezes while running Boot Camp. It appears that the fans aren't turning on. I run Windows 7 x64. The CPU is a Core i5. I see lots of mentions of this on Apple's forums and elsewhere, but no solutions.
I measured the temperature while running Mac OS X and while running Windows 7, and verified that it's simply much hotter under Boot Camp.
What is the reason?
