The next great PC bling.. diamond thermal paste

[scaR]

Turns out using diamonds in thermal paste can increase heat dissipation by as much as two to five times over silver. Of course it's not that cheap, but test results have been encouraging enough to possibly develop a market.

diamonds are a geeks best friend?

I waiting to see if they post temps after two weeks with the diamond paste. Even if it drops by the same three degrees, that's 26 @ idle. One below room temperature!

thats wierd, as a chem student i know diamond should be an insulator as there aren't any free electrons to carry heat energy...

WHat it must be is graphite , same carbon in a different form..

The actual chemistry of the paste might be something way off, like some crystal of a metal...

more likely than not diamond paste is just a name , nothing to it .

Actually if you read the article they mixed up their own paste using pure diamond dust and silicone grease until they got a nice consistency.

I'm thinking the diamonds work like gravel in a concrete mix. In other words, Its filterer. Since applying to much paste in the first place cause a rise in temperature, the diamond dust might reduce the amount of total paste used and maximize the thermal transfer properties of the paste. OR maybe the entire crystal lattice vibrates and so trafers heat more efficently. Who cares, once it works.

ent @ 1ce it works...

thats some crazy temp drops man
