Take Control with Nexus PWM Fans [ 92mm ] [700-2500 RPM ] [ From 15 dB(A) ] Air Flow Up To 44 (CFM).
Nexus PWM 92mm Quiet PWM Fan
After leading the market for many years with our BASIC series silent fans we thought it was time to release our PWM creations in the market. 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 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.

* Measured in an ISO certified chamber with 15 dB(A) background noise.
Nexus provides the exact details of our noise level test as we feel dB(A) values are difficult values to compare as there are many ways of testing and calculating. In
the market there are a lot of unrealistic dB(A) value-claims which are often calculated by means of extrapolation. This in fact does not give a realist view of the
fans noiselevel performance. We provide the real figures, from the actual tests. Judge for your self.
About the anechoic chamber
The noise testing is done in our chamber that has been established according to ISO-3745, ISO7779 standards. The chamber has a background noise level of
just 15 dB(A) and was designed especially for fan acoustical noise measurements. We take the utmost care to do thorough and stable tests.
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.
