I've been running Vista on my 17" 2.16 MB Pro and its burning up. It does this because it never throttles the CPU as best as I can tell. I tried playing with the various power profiles to no luck. Under device manager, there is a device called performance analyzer or something (I forget exactly what as I'm in OS X now) that doesn't have a driver. I have one of the last 17" CD (not C2D) models which is otherwise problem free. I'm convinced the lack of throttling is the source of the heat. I tried the latest Apple Boot Camp drivers, but that only fixed sound beyond what Vista already had installed. Also, USB seems slow (1.1 speeds, not 2.0) on a thumb drive, but not positive there. Any solutions to get it to throttle the CPU? If it makes any difference, I'm running a legal version of Vista Business, not a pre-release RC or beta.
