what is needed is something like this.
http://www.amiga.org/gallery/index.php?n=1858=10glue heatsink permanently to the permedia 2.( ARTIC SILVER ).
if the fan go's faulty you still have a heatsink attacted to the permedia 2 also note you can change the fan by the four screws.
a good idea is to connect the fan power point 5v on the Cybervision/Bvision card itself,this will make the card more plug-in & play. no trailing wires.
look carefully you can see the PHASE 5 heatsink has been cut to fit the heatsink.
this is a old project but is awesome cooling down the 603e ppc.

EXTRA NOTES: only use heatsink/fan combo where the fan can be changed. ( very important ).
