im making a back plate for pwm (northbridge already done... did a little write up about it here)Originally Posted by Aldy402
my ghetto solution to the cooling the mosfet
a 40mm fan, a long screw and a nut. I just used the existing screw hole on the back sink
works very well...
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
