Bill, Re: best heat transfer paste

I did a little research and hope my order for Arctic Silver arrives today.

Review of multiple pastes and a pad on an OC P3(Katmai)-550@645:
thetechzone.com

"Science" article that I actually haven't read yet:
electronics-cooling.com

Homepage for Arctic Silver (includes links to many reviews)
arcticsilver.com

The Arctic Silver was more expensive but enough product for multiple applications rather than single packs. If both the processor and heatsink are very smooth then very little is needed.

Most of the reviews I found were very skeptical of pads. They seem to be mostly for ease of installation. Some of the newer ones worked much better if "burned in" at perhaps 60C (ie. turn the fan off and it warms up fast) to allow a phase transformation.

Bill re <<Out of curiosity what are the best heat transfer pastes?>>

Depends on your interface gap. Basically the smaller the gap the less viscous you want your paste to be. If you gap is huge, pads work the best.

For CPU's, medium filled high aspect ration silver flake work best. They generally can provide thermal conductivity of about 3.5 W/m.k in gaps of few mils.
