First off.. The electronics stuff I know is from some basic stuff I learned in college for system programming… I played a bit with some and gates, or gates and multiplexers but that is going back 7-8 years ago…

I would think that attaching the heat sink to the tab would be ideal. But they are soldered to the MB. Currently they are using the MB as a heat sink. I believe that attaching the heat sink to the top area on the FET would be better then the bottom of the board cause you are now cooling the FET directly and not through a multilayer board.
my 2¢
