Do you have a name for a particular product? Something i'd def be interested in. Since I have the fans already I could post a quick thread showing the results too.
As for the bitfenix fans, I don't agree they are inaudible at low volts. Yes, they are very quiet, but like many fans they suffer from 'switching noises' which is like little clicks you hear constantly if you put your ear close, noctua fans don't have this clicking noise due to special tech.
Smooth Commutation Drive 2
The latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-S12A remarkably quiet even at very close distance
And I just noticed from their site they have a new S12A FLX, looks awesome actually. Probably will be the most quiet 120mm 'case fan' in the world.Edited by ilikebeer - 2/15/13 at 5:34am
