So my big bad blue anodized Zalman heatsink that I super glued on each corner of the Permedia chip fell of my card today when I removed it from my A4000.
Maybe just as well, it did not cool GFX-board that good, it got really hot. I suspect you really Really need a fan on the P2.
I need to find another solution. Prefearably one where the heatsink is attached to the graphics card with screws, and a heatsink that will take a 30 or 40 mm fan.
No, -duct tape, wires or zipties wont do it for me 8-)
Anyone got a solution to the problem?

I've mounted a 60mm case fan in the front of my A4000 Desktop, to blow air over the CybervisionPPC and the CPU board itself, it always stays stable, though I do have a small heatsink stuck to the permedia chip too.

I think I had just a 40 mm fan on the Permedia, fixed with just one screw to blow on the chip surface; lazy me...

what is needed is something like this.

glue 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.

do a better finish than i have as the above links were test heatsink.
EXTRA NOTES: only use heatsink/fan combo where the fan can be changed. ( very important ).

Ouch! Superglue?! That has the heat-conducting properties of a well-insulated banana!
How about re-attaching it with something like this (http://www.arcticsilver.com/arctic_silver_thermal_adhesive.htm)?

i bought a pack of 8 stick on memory heatsinks for a fiver from maplin,
three fit on the P2 chip
three fit on what i guess is a pci bus chip
two fit on the small chip by the connector that also gets pretty hot.
with a 40mm fan sat above it. and this is in the confines of a desktop A1200 case...

I actually used thermal compound also, but I left four tiny spots for super glue on the corners. Its an old way of mounting heatsinks, goes way back when the blow hole and fanbuss was invented.

This is what I used in mine...
