    This is fascinating. Sandia National Labs have developed a spinning heatsink and it looks brilliant!

    I'm sure some of you have already seen this but have a read. CPU air cooling could just be getting a lot better soon and you all know what that means... :thumb:

    Interesting, though I find 2000 RPM being 'too fast for dust to build up' a bit dubious. Though if the velocity of the air though the fins is fast enough it could be better than a fan at 2000 RPM dust accumulation wise.

    And as for an air bearing and heat transfer, youre into an odd bit of fluid dynamics where the whole thing is a boundary zone (i.e. no lamanar flow) which could bring forth a bunch of odd effects that a static .001" gap wouldnt have.

    I wonder what their measure of effiency is though for the 30x claim. watts dissipated per watt input? given how well air bearings work, its plausible. 1/30th the thermal resistance? probably not.

    Vague article needs more details, but definitely interesting.

    Yes and the accompanying video is no more informative. However, if these claims turn out to be half correct it's still an interesting prospect.

    My LED's do get really hot so this cooler will be great.

    I'm sorry... but i've had faster fans that 2000rpm in the past, and they've gathered dust.

    Still... looks interesting.

    I don't see how an air pockets going to be anywhere near as efficient as TIM at transferring heat.

    Until/unless they somehow make it work when it's mounted vertically, we won't be seeing it in any typical systems any time soon.

    Maybe it's not actually an issue, but from what I saw in a video on this stuff the fin/fan assembly rises up from the motor assembly in operation; but I can't see that working quite the same way if the whole thing is on its side as in a standard ATX tower build.

    Even if this works really, really well, I'll stick to the Frio until CPUs get properly hot again.

    One thousand of an inch clearance.

    Have they seen how "not flat" cpu heat spreaders are?

    Best of luck fitting one of them to an everyday cpu :)

    Obviously not an ivy bridge owner :)

    By the way... I first saw word of this spinny tech about 3 years ago or more. It has advanced now because they have given it a name. Other than that it's the same spinning heatsink that was promising outstanding performance some years ago.

    I kind of wonder if this will ever emerge and if it does, will be be another liquid metal magnetic pump cooler that costs £100 and doesn't cool as well as a heatsink half the price?

    That's the exact impression I got from it too; given how marketing-laden the videos are.

    I'm still waiting for those LED heat pumps personally...

    lol "soon" the op says :p. That research was published nearly a year ago ^-^; I came here and thought they made the advancement into the consumer space but I guess not :(.
