LOL, yeah, we do tend to get carried away! :)

And BP, I'll see if I can find the datasheet for the FETs in the Quark (since I know what those part numbers are). You'll see that the current rating falls quite rapidly at anything over 25*C. IIRC, at 50*C, current capability is halved. And you have to remember that your temp measurements are being taken from a heatsink attached to the FETs plastic case. Not exactly the most efficient transfer of heat...
