be quiet! Shadow Wings 2 120mm PWM offers whisper-quiet operation and reliable cooling at low revolutions per minute. Key features include: Low-noise operation of up to 15.9dB(A) Airflow-optimized fan blades Anti-vibration mounting system prevents transmission of vibrations Rubberized fan frame minimizes vibrations High-grade rifle-bearing technology Secure and easy installation with push-pins PWM controlled fan speed through the motherboard Product conception design and quality control in Germany 3-year manufacturer’s warranty Whisper-Quiet Operation Due to airflow-optimized fan blades The Shadow Wings 2 120mm PWM fan blades have been optimized to ensure maximum airflow resulting in a whisper-quiet operation yet solid cooling. They operate at only 15.9 dB(A) even at its maximum speed of 1100 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 80000 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.
