The be quiet! Silent Wings 4 120mm PWM is a high-quality case fan designed for users who prioritize silent operation without compromising on airflow performance. With its sleek black finish and compact 120 x 120 x 25mm form factor, this fan integrates seamlessly into a wide range of PC builds. It weighs 190 grams and comes complete with mounting screws, making installation straightforward.
Optimized Airflow and Pressure
The Silent Wings 4 delivers a maximum airflow of 49 CFM and a maximum air pressure of 1.79 mmH2O, making it suitable for use in both open fan mounts and more restrictive airflow paths such as radiators or dense filter setups. The fan reaches a maximum rotational speed of 1600 RPM while drawing only 0.13A and consuming just 1.44W of power, keeping energy usage impressively low.
Silent Operation and Precise Control
Thanks to its Fluid Dynamic Bearing (FDB), the Silent Wings 4 operates with minimal friction and reduced noise over time, contributing to its remarkably low noise level of just 18.9 dB(A) at full speed. The 4-pin PWM connector allows the fan speed to be precisely regulated by the motherboard or fan controller, enabling the fan to run even quieter during low-load scenarios. There is no LED illumination, keeping the focus entirely on clean, silent, and efficient airflow performance for productivity-focused or noise-sensitive environments.
