What would be the best type of grease to use to conduct heat from the transistors to the heat sink. Original was white in color.

Thanks.

Just use some regular bird shit.

It's called bird shit for a reason ya know :smoke:

I've contemplated using a thermal compound for computers called artic silver, a silver bearing compound that is supposed to have better heat transfer properties but have never done it, only thought about it.. anyone else?

Lots of studies on the subject, and the findings show that properly applied cheap-azz white silicone grease works 95% as well as the expensive Arctic Silver (or similar) stuff on CPU's.

The heat density in an output transistor is nowhere near what it is on a CPU die, so the additional expense is wasted IMHO. Additionally, the thick Arctic Silver stuff is very difficult to apply evenly over a large area, like an output transistor.

That's good to know. Currently, I've been using Shin-Etsu Microsi Silicone compund made for P-4 CPU's. I basically get it free though.
