BTW, I putted heatsinks in (almost) all custom chips in my Miggy,
for the very same reason.
Look for "Geforce Heatsink plus Fan Kit". They come with eight small hs with 3M glue pads, plus one big copper hs with fan (who rests in my Geforce4 board).
The heatsinks for the CPUs can come from dead peecee MB. I put a northbrige hs in my 030/56 Mhz (sic), a southbridge hs (you can put a jigsawed northbridge, too)lies over the FPU.
And an "external" notebook fan lies besides the acelerator, cooling CPUs and the 128Mb SIMM. No more photos yet.
