The Thermal Paste Revolution

arhines writes "ZZZ is running an article about an interesting new thermal paste which surpasses even solder in thermal conductance by 33 percent. If this paste makes it to the market sometime soon, we'll all surely be thinking about putting it in our boxes. In fact, if use of the paste becomes commonplace, it may even give the semiconductor industry a little speed boost."

    They seem to have just duplicated the inventor's press release - the article doesn't contain any independent evaluation of the substance whatsoever.

    I think you misunderstood the statement. They may have compared the thermal conductance of this material to solder, but they're not looking to replace solder. Solder is made up of metals, so it's naturally a good conductor. But metal doesn't spread very well over microscopic cracks -- and no, you can't fill in the cracks with solder, because the metal will contract when it cools and be useless as a thermal paste. You wouldn't want to use a thermal paste as a solder, because thermal paste typically takes a very, very long time to dry when not exposed (ie: between a cpu and a heatsink).

    So it looks like CowboyNeal is saying if this new thermal paste can improve the effectiveness of a heatsink (and fan) by a reasonable amount, manufacturers will be able to push their clock speeds a little higher.

    If possible, switch on the machine for a few minutes before removing the heatsink.
    This will heat the CPU and it will usually melt the thermal paste. It should now be easier to remove the heatsink from the cpu.
