    A few days ago I read a story about a "carbon like material" that was 58% times stronger then diamond. So this can be truthful.

    I don't doubt that this compound has higher thermal conductivity then copper... but will it ever be affordable enough. Making usual carbon compounds like these, carbon fibre, nanotubes and graphene all suffer from limited growth because of their prohibitive manufacturing costs.

    A solid silver heat sink would be better than copper, but it doesn't matter because its too expensive.

    So basicaly - it transforms heat to light? I love physics :D

    No, the transfer is from phonons, not photons. They're different things, although they are rooted in the same mathematical description from statistical mechanics. A phonon is best though of (as long as you don't want to start bustin' some science on it) as the vibration of a molecule within a lattice vibrating. The "connection" with the other lattice sites allows for a fast transfer of vibration, much faster than the poor old conduction electrons.

    This sounds like an interesting material and if it can be made cheaply enough, a great alternative to an all-copper heatsink. After all, carbon is pretty damn abundant, whereas copper will inevitably run out sooner or later.

    metals prices have started to go up... this is a logical step in the right direction.

    Paying through the teeth for 5°C which isn't set in stone... pfft!

    "This differs from heat conduction via a standard metal heatsink, which relies on the movement of electrons in the metal."
    Electrons? What? When did the Laws of Nature change without anyone telling me?

    heat is the energy that particles posses by vibrating, passing that vibration onto other particles is how heat transfers trough solids and fluids. (it can pass trough a vaccuum and transparent materials as radiation)

    I dont know if Ben just copied it or wrote this himself, so i wont automatically direct this at him, but the guy who came up with that is a class A idiot.

    Meh. I take 30° off my cards simply by putting them on water. :p

    In all seriousness, I'll believe it when I see the proof.

    so is this like that IC 7 Diamond thermal compound but just even more refined?

    no it is some carbon fooled into thinking it is diamond... and it acts like it too, so it (should) conduct heat better

    I'm going to need proof of it first before even thinking of buying it

    why don't they make heatsink out of the stuff they used to wildfireproof a house from smash lab, it was amazing it resembled plexi but it doesn't even burn and transfers heat almost instantly, they put it under a torch for a few minutes and was able to be handled with bare hands almost immediately. they need to make heatsinks out of that stuff.

    That "stuff" is an insulator, it work very poorly as a heatsink. The reason you could handle it straight away is because it doesn't absorb any heat.

    This sounds expensive.
