Cooler Master engineers a rotating heatsink
Okay one word, concept ! Cooler Master has been showing a Kinetic Cooling Engine, a new heatsink concept that was originally designed by the Sandia National Laboratories and is now licensed by CoolChip Technologies.
The unit primarily intended for mobile and small-form factor systems, the Kinetic Cooling Engine promises to deliver 50 percent better cooling than traditional solutions at half the size and with significantly lower noise levels. Tech Report saw the cooler in action and reports the new cooling solution was "silent" compared to the "noisy whine" of laptop-style blower.
One of Cooler Master's desktop prototypes surrounds the spinning heatsink with a ringed radiator that hooks into the base via heatpipes. Cooling duties are split between the radiator and heatsink, and because the latter generates its own airflow, there's no need for a separate fan. Despite the extra radiator, the cooler remains relatively compact—and much shorter than typical air towers.
Cooler Master might want to add some sort of grill to prevent errant fingers from being shredded by the heatsink, though. Getting nicked by plastic fan blades doesn't feel nice, and I imagine those metal fins do a lot more damage when spinning at high speed.
If you want to learn more about the technology, check out this Sandia whitepaper (PDF), which explains the approach in great detail—and with a lot of math.

If they start putting this in laptop's I can imagine the number of people getting their fingers cut by fooling around and opening their laptop's.

Not that many people do that as it is though. And even less people would do it while its powered on with the blades spinning.

I remember reading about this design quite a few years ago and didn't think it would see the light of day. Guess i was wrong. It's going to need super precision manufacturing tolerances.
This design will suffer from failing bearings from the heat drying out the bearing grease.
Bad design I think, There adding problems for a few extra degrees of cooling.
Why do you say that? Last I checked, the bearings in hard drives spin far faster and typically outlast the rest of a drives components.
