BTW -- we are using the temp sensor on the processor -- so make sure any mods you do reduce the temp difference between the FETs and the processor, not the opposite.
What does that mean -- 2 month clean-room run? Are you thinking about getting On Semiconductor to give us some Fab time, or what?

Well, true for the last gen. pcb with only 6 fet's down there... still can see slight improvement. If you plan to add copper heatsink to MM, than I am sorry who needs MMM in 1/8 scale? You can do the same to MMM, of course. Just get plated copper, so it doesn't change its appeal :)
I know, on first versions I was adding copper spacer, but lately reusing your foam, works alright. :)
Something like that, but not at On Semiconductor, more like proto run at University and upon success, I do not know it is way too early.
