Thermal compound

Postby trev260764 » 16 Nov 2014, 11:03

Just abut to run-out of thermal-compound. I note there are some bargains to be has from China when ordering a few... Anyone know whether the stuff used on computer heat-sinks is the same? There are thousands to choose from if it will do the job!!

If you could get a datasheet for the china stuff, then it would be easy to decide.

Computer heat sinks will not go above 100degC whereas GHDs will see 200degC. Therefore the paste needs to stay paste like (rather than going to liquid) up to that temperature.

You also need to compare thermal conductivity.

I can't think of anything else to check.
