We cut the PC heatsink in half and took a few fins off, thinned the heatsink base until it fit inbetween the fets and drilled 4 holes in it. Used 2 strips of ally each with 4 holes (just as washers really) and bolted them either side of the fets to squash the fets to the heatsink with lots of heatsink paste inbetween and bolted them on.

Dont surpose anyone took pictures of this at Magna?
