The fanless spinning heatsink: more efficient and immune to dust

[A Guy]

I give you the Air Bearing Heat Exchanger [PDF]. Developed by Jeff Koplow, a researcher at the US government’s Sandia National Laboratories, the new heatsink (which has also been dubbed the “Sandia Cooler”) basically resembles a big, metal fan. The cooler consists of a static metal baseplate, which is connected to the CPU, GPU, or other hot object, and a finned, rotating heat exchanger that are cushioned by a thin (0.001-inch) layer of air. As the metal blades spin, centrifugal force kicks up the air and throws it up and outwards, much like an impeller, creating a cooling effect.

The fanless spinning heatsink: your questions answered by the inventor

After we covered the fanless, dust and detritus-immune heat exchanger last week, we were inundated with questions about the new technology. How does it work? Does it really use a thin layer of air to transfer heat — and if so, how can that possibly be better than copper or thermal grease? Is it really immune to dust, or are you just being hyperbolic? Are you sure that it can actually save 7% of annual electricity consumption in the US?

Thanks for the great read A Guy! I for one, will be very interested in watching how this develops.

Thanks A Guy interesting alot of talk is about the 3.0 Ghz chip, i have seen Sandy bridge shipped at 4.5, on air and i can get 4.6 with the only problem that concerns me is the NB gets a bit hot apparently normal for the board.. as Bear mentioned if it is a good technology it will develop quickly...i will have to download the pdf file and have a closer look..

Still not sure if I will overclock my i5 CPU. I guess it all depends on performance and if I ever decide to do more gaming. I suspect that having the OS installed on a SATA 3 SSD will give me all the performance I could ask for without overclocking, but we shall see.

You will never need to overclock. It's more about the itch Your PC will be all you can want right out of the box. A Guy

Well, I'm thinking that controlling that "itch" will be a struggle, but I'll give it my best shot! Thanks as always for the reply Righteous Dude!
