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

The be quiet! Silent Wings 4 BL093 is a 120 mm case fan engineered for low-noise operation and versatile cooling applications. It incorporates a 6-pole motor paired with a Fluid Dynamic Bearing (FDB), which work together to reduce vibration, minimize power consumption, and ensure a long operational lifespan. The fan's blade and frame design is structured to perform effectively in various scenarios, from providing general case airflow to being mounted on CPU heatsinks or liquid cooling radiators. This makes it suitable for PC builds that require dependable cooling without excess audible output.

Controlled via a 4-pin PWM connector, the fan's speed can be automatically adjusted by the system up to a maximum of 1600 RPM. At this speed, it generates an airflow of 48.7 CFM and a static pressure of 1.79 mmH2O, making it capable of moving air through restricted spaces. Even at full load, the fan operates at a noise level of 18.9 dB. Its standard 120 x 120 x 25 mm dimensions and included mounting hardware ensure straightforward installation in most PC chassis.
