I recently picked up an ECS A939 motherboard
for the Athlon 64 FX which had failed for the
previous owner. The failure was caused when the
heat sink unit for the Northbridge chipset
fell off, thereby allowing the chipset to fry.

I looked at the heat sink and it was glued to
the chipset with double sided sticky tape.

Not phase change thermal tape?


He is talking about the chipset heatsink not the CPU one.

I've used thermal tapes such as the following. They are impregnated
with metal foil, are very thin, and bond *very* strongly. However they
are very expensive.

The Kool-Pads brochure talks about "HI-FLOW 105 'phase change' polymer
coated aluminium designed to replace grease as a thermal interface".
It has an adhesive coating. There is also "HI-FLOW 625 film reinforced
'phase change' material" with an adhesive coating.
