Is the Sandia Cooler ever going to be made ? (fan blades for heatsinks)

Surely this would never work on a cpu ?

Why couldn't it work? And who knows when it will be made

Hi
It would work but I suspect that they have some problems to solve before it can be mass manufactured.
Such as the motor and fan bearing are heated by the CPU prior to the cooling effect of the blades this will mean operating in temperatures up to 100 C.Can this be solved,yes but the cost could be prohibitive.

The primary bearing is air (hydrodynamic), so that doesn't matter. The secondary bearing and motor would get hot but if properly designed they'd easily outlast the 5 year service life of the average PC, and given the thermal transfer rates posited, they'd only get to high temps if the fan was stalled.

Hi
Hydro(water)dynamic means that the bearing is a fluid which will certainly heat up but it and the related seals can be designed for this but cost may be an issue.

The bearings of the Sandia cooler are more accurately classified as fluid bearings, specifically fluid dynamic or aerodynamic fluid bearings that use atmospheric air as the working fluid (remember, a fluid can be a liquid, a gas, or a mixture of such). Air is not an especially good conductor of heat, but the huge surface area of the bearing, plus the fact that the air film is very thin and subject to strong shear forces means that the overall thermal resistance is still very low.

Once upon a time you didn't dare bump your computer in case you upset/damaged the HDD (head slap)

With a Sandia cooler you won't dare bump your computer in case you cause the fan to slap.

I still want to see these in the marketplace though.

According to this pdf https://www.google.com/url?sa=t&source=web&rct=j&ei=HJSvVOatN4W4oQTY0oKIDQ&url=http://energy.gov/sites/prod/files/2014/10/f18/emt33_koplow_042314.pdf&ved=0CBwQFjAA&usg=AFQjCNEIy7fzJJF8ghcs56CPafln_hdCpg&sig2=2pVxcLFNlYZwo0La7laFGA it was delayed for motor control issues. Prototypes have been done for 6 months. So probably still testing.
