Are you running Vista 64-bit?Well I have gone through four machines, all of them suffered by it. You do realize that you need to run the same program to prove the point. If you want to see if yours suffers from it, do the following. Install the latest World of Warcraft expansion, set all your settings to high and play it for a couple for hours, then tell me if you get the BSOD. I can replicate it every-time. The thin design contributes to the cooling issues, and yes I can absolutely say that the FANs do not kick-in fast enough, People who game on MBPs are forced to run third party fan controllers.
It should be noted that the only Mac with official BootCamp support for 64-bit Vista at this time is the Mac Pro. It's Vista 32 for you until Apple gets their thumbs out of their butts and releases BootCamp 3.0 (or whatever version number it gets).
