All our expertise and experience is put in these PWM fan models. We have strived to set them up with the best possible characteristics. Great performance and extreme low dB(A) ratings is guaranteed. We achieved an amazing 15.8 dB(A) noiselevel at 700 RPM. (measured in a chamber with a background noise of 15 dB(A)) Take control of your fans...and hear yourself think again. Pulse Width Modulation The use of a 4 wire PWM controlled fans is a means to reduce the overall system acoustics. The expectation is a 4 wire PWM controlled fan when properly implemented will be significantly quieter than a similar 3 wire fan. The Nexus 92MM PWM Series case fan has an extra big fan speed range. This allows the fan to be ultra quiet at low speed and provide massive air flow at full speed in case thing get too hot. Great control over a massive RPM range.

 Does the job wellNov 09, 2011

"tech weary"
Nice, quiet fan that moves quite a bit of air. I installed two of these, one to replace a rear fan and one in addition to the main front-of-case fan. I still have cooling challenges, but that's because of my Micro ATX case.
To replace in my noisy serverNov 04, 2011
By Jeff Simon
I ordered these from amazon, which arrived on time and exactly as described, to replace the 6 120mm fans in my test server at home. If i would be using them as they were intended, i would be more qualified to give a valid review. They are really quiet, while i had it on. I've re-soldered the leads from my dell fan plugs to these to lighten the DB load on my ears...

These fans are quiet! I bought a front and rear set for my new computer I built. I needed a fan that was variable speed like these. They have a four wire connector that plugs into the mother board. These fans are not screwed to the case, they use an innovative rubber mounting system. It is pretty neat and makes the fans even quieter. The 120mm fan in the rear of the case works great. The smaller 92mm fan didn't last 2 weeks. So this is the second fan in the front of the case. I will let you you if it keeps on a working.
