Anyone added new thermal paste before? - stormy - 06-18-2019
As the topic states, I was just wondering if anyone has tried putting Arctic silver between the CPU/heatsinks GPU/heatsinks.. regardless off sgi model.
Surely replacing old crusty thermal paste might be a good idea...

The majority of the systems use thermal pads or adhesive, so plain old paste doesn't work. Yours truly destroyed his O2 300MHz R12k that way

Ohhhh, so they might be designed with the thickness of a thermal pad in mind... I see. Not enough pressure to make proper contact with paste etc.

Correct, if you take the sinks off lots of them have a rubber or mesh lined sponge type seal around the edge. They can only compress so much before they leave a little gap between the cpu and heat sink. When I did my O2 mod I bought some thermal pad, can’t remember the thickness but it was around 0.6mm.
The heatspreaders and heatsinks aren’t exactly mirror finish flat either so pads help take up any irregularities.
