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.
