be quiet! Silent Wings Pro 4 120 mm PWM Case Fan - White

The be quiet! Silent Wings Pro 4 is a 120 mm fan engineered for applications requiring high static pressure and airflow. Controlled via a 4-pin PWM connector, it reaches a maximum rotational speed of 3000 RPM, producing up to 83.9 CFM of airflow. Its static pressure rating of 5.31 mmH2O makes it particularly effective for moving air through the dense fin arrays of liquid cooling radiators and large CPU heatsinks. Motherboard-based PWM control allows users to manage fan speed to balance cooling performance against acoustic output for their specific needs.

This model incorporates a fluid-dynamic bearing (FDB), which is designed to reduce friction and vibration for quieter operation and a longer component lifespan. The fan's seven-blade design is aerodynamically optimized to maintain consistent airflow and pressure across its operational range. At maximum rotational speed, the fan operates at a noise level of 36.9 dB. This version of the fan comes in an all-white housing and blade assembly to integrate with builds that have a corresponding color scheme.
