Fanless Spinning CPU Heatsink

[LaughingCrow]

Well, believe it or not, rotating the heat exchanger obliterates the boundary layer, removes the need for a fan, and it’s so efficient that it can operate at low and very quiet speeds.

That's pretty darn interesting. I would probably consider getting one for a future build.

About time someone considered this pathway to cooling.
Done correctly this can be extremely efficent and very lucritive.

Here is to hoping that it develops into something more.

that probably coulda worked well in my ShortStack build.. lol

wow that looks really cool, would love to see how it performs and what the future holds for HSFs like that.

If you look carefully at the design specs, this isn't that great of an idea. At most it might replace stock heatsinks.

1. The fan motor is very close to the thermal load.

2. The current design requires 10W to operate, the future revisions will feature a more heavy duty higher consumption motor, driving up consumption.

3. There is 3 nanometres of air conducting heat from the base to the fin array, it seems there aren't any good material candidates to replace air at this time.

4. Performance will diminish significantly when higher RPM's are required, due to friction.

All this design really does is it eliminates the dead air layer that insulates traditional downdraft heatsinks, which only increases the efficiency of fin to air heat transfer. Most enthusiast/high performance/server heatsinks aren't affected by this issue.

holy crops!!!

thats cool lol

but..wait..what about the dust?

Ahhh perhaps but being an early stage prototype it is still a long way from being marketable. There are a lot of engineering fixes that need to be applied to make it practical but I can see potential.

its a vacume single stage blower... sucks it out blows on your caps

Looks promising but people have overclocked chips to ~5GHz, what's stopping em at 3?
