Desktop Computer Review: Nexus 120mm Real Silent Case Fan D12SL-12 Review

This is indeed the quietest fan that I've heard.Running at 12v inside the closed case, I can hear it from 10 feet away, but only late at night, when everyone's gone to bed and everything else has been turned off.I can barely hear it over my 32" CRT TV.

At 7v, this fan is nearly silent, and is inaudible a foot or two from the case.Air flow is expectedly reduced at lower voltages, so you might need more fans in your case (I have four), but if they're made by Nexus, you certainly won't hear them.

Note:At 5v, the fan cannot be heard from one foot away with the case open, but air flow is too greatly diminished to be useful in most situations.I would recommend 7v; you won't be disappointed.

Product Description:
Nexus 120mm PWM Silent Case Fan - D12SL-12 PWM

Nexus has lead the market for many years with their BASIC series silent fans and have finally released a PWM version. All of their expertise and experience is put in these PWM fan models. Nexus has strived to set them up with the best possible characteristics. Great performance and extreme low dB(A) ratings is guaranteed.

They achieved an amazing 15.5 dB(A) noise level at 500 RPM. (measured in a chamber with a background noise of 15 dB(A).

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.
