All this talk about lapping...

So how 'cool' would it be to use a diamond-polymer grease between your x1900xt and your cooling solution? This article makes for an interesting read for those of you who like to know whats almost available in the electronics cooling world and who also are creative with their own cooling solutions!

I have some diamond lapping compound for nuclear valves. It's pure silicone with fine suspended diamond particles.

It doesn't fill the cracks and voids in the heatsink/cpu surfaces like a soft metal or oxide does, since the diamond doesn't compress/mold into shape. Could be that the diamonds in my compound aren't fine enough, so I'll hold judgement. BUT: I do get better cooling out of normal heatsink compound or AS than the diamond compound.

Excellent. Well, I would imagine that one would have to find the best way to compress and somehow "shrink" the diamond polymer before suspending it or using it in a compound made specifically for HSF apps and heat transfer.

I remember reading reports about the theories on the diamond particles back at the DOE. You wouldn't happen to be working on those nuc valves at DOE? Just a shot.

Here's more info. on the diamond dust stuff.

LOL...I worked on nuc valves on submarine and aircradft carrier reactors, the DOE are panzies...it's NR and NRC we had to deal with.
