Check this link out: Inventgeek.comQUOTE Anybody who is a true computer hardware enthusiast these days knows that keeping your CPU from overheating while pushing it to its limits is one of the most important concerns. Thermal compounds like arctic silver are the front line of that defense, conducting the heat directly from the CPU to the heat sink. Without the compound, small imperfections in the surface of the heat sink can render the heat sink almost useless and lesser compounds can actually insulate your processor. Thermal compounds that are available for purchase have remained unchanged for some time. So I descided it was time to reinvent my thermal compound needs with some diamond dust! it provides a 10 degree celcius drop over as5  , and it's not as expensive as you might think.. the only way to prove the credibility is to do it.... care to give it a try? first thing first, where to get rough diamonds here?

oO?... DIAMOND DUST?... carbon good conductor of heat meh?.. =.=

I feel "sakit hati" when I clean the thermal paste off. I think I won't even remove the heatsink after years.  |

It will only eat the compound if you rub it or clean it with tissue or other stuff other then 97% pure alcohol |

This is a cool idea, didn't realise someone already went ahead and did it. The diamond powder will only eat into the heatsink base & IHS if there is movement, so for the most part its not going to be a problem (In fact, you'll have a self-lapping, or rather self-polishing HSF+IHS if the diamond powder you use is fine enough).

If ur using a high powered fan on the HSF that .... what will the vibration do to the hsf and the proc? ...  |

If both the proc and HSF vibrate together (pressed tightly together) there will be minimal effect. If both are vibrating against each other, it will slowly lap both sides, but since the vibrations from fans are not that high an amplitude, it will probably take a few months before you'll even notice anything when you take off the HSF.

But its not worth trying considered the price and the effects...

Anyone interested to try?  We can share the cost and do it together. I'm sure it's enough for everyone's CPU. |

It is known that diamond is the best heat conductor. Imagine a heatsink using diamond...... Intel is using that, because of the good conductor but also because they can see through to look at their CPU..... it was mentioned in one of the reviews.....

A whole heatsink made of diamond? Highly unlikely. Maybe just a thin conduction plate (more like superconduction). Diamond's refractive index is too high to really see though it without the images being distorted. Not to mention that even a heatsink made from industrially grown diamond would cost more than an entire intel factory, and finding a natural diamond big enough is  |

Why do people still compare it to AS5 when MX2 has been the new best of the mass produced thermal pastes?

Well, even MX2 cannot dream of fighting with this.. QUOTE(kmarc @ Dec 7 2007, 04:30 PM) LOL. Not a whole heatsink la. Probably a thin plate, like you said..... Look here (page 6): http://tweakers.net/reviews/740/1/chip-mag...m-pagina-1.htmlYeah, it almost guaranteed its a thin plate, even then it will still be like imaging the processor though a very thick piece of glass. One thing for sure, it will definitely be flat, or using the laser to break circuits would be impossible because focusing would be impossible.

how am i going to find cleaning material for a diamond?  wow 10 degrees? which website got that result? from my reading source, it offers 3 C improvement ovr AS5 and they didnt state anything about AS5 curing time or whatsoever. This post has been edited by campsol2k: Dec 8 2007, 06:09 PM |

Anything that cleans normal thermal paste is fine. The homemade diamond paste mentioned by the first link was done using diamond powder and silicone thermal paste, and got that 10C result.

diamond is the top of the list in heat conduction followed by silver, copper and aluminium. It is also an excellent insulator against electricity due to the atomic structure that tightly holds the valence electrons... anyways, industrial diamonds aka articifial diamonds can be used for this.. but a caution though, when u mix this things, make sure u wear a mask, or u will endanger yourself.
