I don't trust the phase-change crayon stuff. It's likely to leave air
I totally agree.
I've gotten the Aavid Ultrastick phase-change goop down to what I
thought was about 1-2mils after clamping. It flowed like water when
hot but never got any thinner than that. And that's with belleville
washers, etc.
The grease I'm using now starts at that thickness (if I put it on with
care) and then just gets thinner with pressure. Their thermal
conductivity specs are pretty close so I'm going with the grease.
I'm using the Wakefield 126 Series stuff now but Dow TC-5022 looks
great. Several times the conductivity of the 340 grease. I have a
sample on order and will see if there's any difference. At these
thicknesses though, I can probably use mayonnaise and still be OK.
