    diamonds and carbon are the 2 best conductors of heat i think

    Is carbon expensive?

    Not much if DeBeers would release some more damn diamonds. Even if they don't however, diamonds are now being synthetically made in the labs so for non-jewelry use I think the price would come down in a few years provided that they find a way to use it efficiently (demand is irrelevant as those die-hard enthusiasts would snatch them up).

    Carbon fiber is an insulator.

    I think the card was made so you have to buy these blocks :shadedshu

    Pure carbon in it's diamond form is THE BEST HEAT CONDUCTOR KNOWN TO MAN, period. As you all know, it's insanely expensive. But, there's a cheaper mineral that Has a slightly lower heat conduction - aluminum nitride. I dunno how expensive is to make coolers out of it, but they should have supreme performance. :cool:

    Toothpaste and Olive Oil FTW. Or perhaps AXE Bodysprays, or cologne.

    There you go...

    Some eye opening info between:
    Cooper and Gold
    Silver and Diamond
    Aluminum and Cooper
    Megasty and DrPepper say thanks.

    In terms of the expense of this thing, a few things to keep in mind:
    Machine time is very expensive (100 dollars or more per hour is not unusual) and copper is relatively slow to machine.
    Copper is stupidly expensive.

    In addition to all the other usual costs, like packaging, engineering, shipping, and so forth.

    @ awesome thermal conductors: carbon nanotubes, anybody? :)

    I'm not too sure on the price of coal :) thats carbon. Humans are also carbon based lifeforms.

    and no TheMailMan78 I didn't forget graphite because its a mixture of carbon and clay used in pencils ;)

    its not like these are one off pieces so material/machine costs are not very high, R/D is however time/money consuming

    With all due respect graphite is a little more than that. Within 5 years your going to see graphite heat sinks without a doubt. Read below. I think you'll find this interesting.

    "Thermal management systems consist of external cooling mechanisms, heat dissipaters, and thermal interfaces. The primary function of heat dissipaters, e.g. heat sinks, is to create the maximum effective surface area where heat is transferred into and removed by the external cooling medium. Heat dissipater performance is characterized by its intrinsic thermal conductivity, physical surface area, and pressure drop (or drag) coefficient (Kraus and Bar-Cohen, 1995). Another variable, the heat spreading coefficient, introduced by Tzeng et al (PCIM, 2000), must be considered when the heat dissipater is a thermally anisotropic material. A high degree of thermal anisotropy reduces the temperature gradient in the component plane and increases effective heat transfer area, characteristics that are most desirable for electronics with high heat-intensity components. The ability to direct heat in a preferred direction is a further advantage of anisotropic heat-spreader materials. Carbon and graphite-based materials are attracting interest as anisotropic heat-spreaders, with another advantage being their low density. Most carbon and graphite-based materials used to date are based around carbon fibers. These are high cost due to the need for high temperature graphitization processes to develop the required fiber thermal properties. A new form of graphite heat-spreader material is described in this paper, based around naturally occurring graphite. Since this material has been graphitized by nature, anisotropic heat-spreaders with high thermal conductivity can be manufactured without carbon fiber-based additives."

    In theory these things will distribute heat better than anything on the planet. Just remember I called it :toast:

    ok i have some copper plate just laying around and some carbon fiber cloth, as well. the wife has the diamonds (i bought 'em, but i no can usey). i've already made one heatsink out of the plate, but no way in hell am i going to use any CF. not yet. i,m waiting til i get some *Thermal epoxy* i have found some stuff that conducts heat around 25 ish. plenty to get it away from the heat source
