""""Oh, and just a quick question: how on earth did you guys manage to get this stuff into the tubes? It's so thick lol!""""

ICD7 aka tastymmannatees

We use a really big pump and load it from the tip.

It's thick for long term reliability on the mount with thermal cycling.

It is just harder to bake out or pump out a solid than it is a lighter bulk loaded "Hand Cream" or wet type compound. Intel recommends > 90%, we push to 94 %. There were higher bulk loads on some prototype compounds we were playing around but But gave us conniption fits on the installation.
