[ET] The fanless heatsink: Silent, dust-immune, and almost ready for prime time  

post #1 of 20
Thread Starter 
Pretty "cool" if you ask me!

Quote:
In the Sandia Cooler, the heatsink itself is the fan. It is a cast metal impeller that floats on a hydrodynamic air bearing just a thousandth of an inch (0.03 millimeters) above a metal heat pipe spreader, powered by a brushless motor in the middle. The end result is a cooler that is very quiet and 30 times more efficient than a fan-and-heatsink solutions.

Doesn't sound silent to me. Sounds very high frequency and annoying as heck... They say its just because the motor is exposed but I find that hard to believe. Show this thing going head to head against a Noctua NH-D14 and I'll be impressed.

Yeah,I hate that high frequency squeal,who knows,at long exposure,maybe it'd even make your ears bleed tongue.gif
Hell,I'd rather take the "traditional" noisy fan over that thing,and yeah,I'm very doubtful about "30 times more efficient" statement.Benchies or it didn't happen...
