I know that there have been reports of blown MOSFET's on 3-phase boards with 125W CPU's; however, what causes them to blow. Do they get too hot and just burn out?

I have a 9850BE on a 3 phase board with no heatsinks on the MOSFET's; however, I have mounted an 80mm fan that blows right on the voltage regulators and MOSFET's...is this adequate or do the MOSFET's actually blow and not just overheat?
