They operate at only 15.9 dB(A) even at its maximum speed of 1,100 rpm. The perfect choice for all who appreciate maximum silence for their PC case.   Anti-Vibration Concept   Reducing vibrations to a minimum Removable anti-vibration mountings on all four edges of the fan reduce vibrations transmitted to the PC case. In addition, the fan is equipped with a rubberized frame that reinforces the anti-vibration concept and ensures vibrations are reduced to an absolute minimum.   Rifle Bearing Technology   Gives the fan a very long lifespan The Shadow Wings 2 120mm PWM is the hallmark of outstanding reliability. This is achieved by its high-quality rifle bearing technology, which assures a very long lifespan of up to 80,000 hours.   Push-Pin Mounting   For user-friendly installation With the Shadow Wings 2 anti-vibration mounting system the fan is simple to install. The push-pins ensure a very fast and secure installation without needing screws.   Variable Fan Speed Function    Varies the Fan Speed Pulse Width Modulation (PWM) allows compatible 4-pin controllers to vary the speed intelligently and thus minimize the noise level of the fan. With PWM your system can ramp up the cooling when it’s needed, or operate at maximum quietness when it’s not.
