i just read it, but i still dont get it why diamond? its not material that conductive, maybe its coz its expensive :respect:

I read an article a bunch of years ago about diamond GPU's and manufacturing diamonds, it was pretty interesting.

If you're considering using diamond as a thermal interface material why not go one notch more insane and use graphene?

From wikipedia entry on graphene:
The near-room temperature thermal conductivity of graphene was recently measured to be between (4.84±0.44) ×10^3 to (5.30±0.48) ×10^3 Wm^−1K^−1. These measurements, made by a non-contact optical technique, are in excess of those measured for carbon nanotubes or diamond.
At worst graphene is twice as thermally conductive as diamond and at best it's an order of magnitude better! :eek:

although its kinda promising, i guess it wont applied much on short time :D

sounds way too close to carbon nano tubes which are just way to expensive to make it to retail. OCZ made a demo model and it showed great promise, issue was it would cost customers like $400 for a CPU cooler. (just a guess on pricing, but you get the idea)

Thermal paste doesn't really matter, unless you care about the 2*C difference. I like MX-2 because it's non-conductive, lasts forever and is easy to clean up after. It does have good conductivity too, but that's just a bonus IMO, as said before the temp difference is minimal... I use it because of the former features.

After running water cooling for a couple years now Nd trying different pastes, the die to IHS on a cpu is more of the limiting factor than most paste. I have yet to see my gpu core report over 5c more than ambient temps, despite being after the cpu in the loop. The cpu runs from 5-10 over constantly.

Completely agree with this statement. When I play with the TEC setup I have, I can change both pastes, between the IHS and the core, and the IHS and the cooler. If I run AS5 under and a good paste over it, it doesn't do as well as if I used the better paste on both sides of the IHS.
