fan on BPPC

[AmiJIm]

hi there,
the permedia 2 chipset sure does get really hot and eventually dies.
Have in mind that all permedia 2 chipset vga AGP and PCI cards made for the pcs,have a passive heatsink.I had to put a fan on to gain stability.
I also have a CyberVision PPC .Luckily ,the Cybervision PPC has 4 holes round the chipset for easy mecahnical support for the heatsink.Remember you need one with a fan.
On the bvision side,i sse the gap .
My personal advice is to avoid thermal paste/glue so to avoid any detach and burn the chipset.plase the heatsink/fan ,and use a plastic wrap belt to hold it in place.either bypass it at the hole in the middle,or from side to side.
take care,you have  a history ultra tech amiga RTG.

oh,i was in the wrong path...
i though bvison PPC.
well the power pc cpu does need a heatsink.Dont mess with the self adhensive pads.

To the solution now.
is the original fan working?It should be enough.
use some oil on the rotor.it should ease the motion and flow air easier/more.
If it is OK and still inadequet,then
i would put a laptop heatsink.I see there are 4 holes around the cpu,so keeping it in place would be easy.

you only have to find a suitable design.
you may have to unscrew and rescrew the fan according to blow or suck the air.
but the theory behind this design is.
take air above and under the fan ,and blow it to in a 90o angle directly on the heatsink.
