NF-S12B FLX
In order to test these fans, we ran the fan well outside the case using a fan controller, and an extension to isolate the noise of the fan from those of the case. What we heard was... well, practically nothing. You could hear the gentle hum of the motor and the bearings, and the whispy noises of the air being moved. This was even on high, when on lower settings it was practically silent, yet there was still a very substantial amount of air being moved. The high angle of attack on the blades allows it to push alot of air at lower RPMS, which further supports its Ultra-Quiet performance. When run at high, and still at near-silence, it moved about as much air as any fan that I have handled, and to do that with only a whisper as evidence, really impressed me.
"The NF-S12B FLX really does its Ultra-Quiet predecessors proud. Decibel for decibel, this fan pushed far more air than any fan that I have seen to date, and its overall performance really almost had me saying 'wow'. There is an impressive amount of innovative engineering going on with these fans, and despite their price, they really are worthwhile." (, Tech-Kings.net)
