i gotta get the hack saw for the back plate but i got a nice candidate... nice block of copper i sourced from the stock heatsink of 1 of my 2900 pros. just heat it up on a gas stove and let the solder heat up... lifts right off. cut off *still have to do this * 2 corners diagonal from each other and the 2 that are left are a perfect fit for the 2 push pins just get some posts w/ springs (got some of those already from extra parts) and you have a nice back plate.

i still have to figure out the fan solution. i have 2 fans that are a perfect fit... just need to figure out the best way to mount them. im thinking using the existing screw holes as you did but making a small bracket from the spare copper fins so i can have it exhaust out the back
great job man, you should really consider watercooling the NB, mines is 35 loaded MAX.

I think I can picture the bracket you have in mind, if your going to exhaust the heat then the fan wouldn't be facing down towards the exposed mosfet area, just the heatsink. The heatsink cools fine but the exposed mosfet area is what really gets hot so you might want to reconsider that..

what are you getting now as your PWMIC temp?
