be quiet! Silent Wings 4 BL094 120 mm PWM High-Speed Case Fan (Black)

The be quiet! Silent Wings 4 BL094 is a 120 mm fan designed for high-performance cooling applications. It integrates a 6-pole fan motor and a Fluid Dynamic Bearing (FDB), which contribute to smooth, low-vibration operation and an extended operational lifespan. With a maximum rotational speed of 2500 RPM, it generates an airflow of 76.7 CFM and a static pressure of 3.96 mmH2O. This combination of specifications makes it suitable for use as a case fan, on liquid cooling radiators, or with CPU air coolers where airflow impedance is a factor.

The fan's speed is managed via a standard 4-pin PWM connector, allowing motherboards or dedicated controllers to adjust RPM based on system temperatures. This provides flexibility in balancing cooling capacity against acoustic output, which reaches a maximum of 31.2 dB. The unit measures 120 x 120 x 25 mm, adhering to the standard form factor for broad compatibility with PC cases and radiators. The package includes multiple mounting options, such as anti-vibration rubber mounts and standard hard plastic mounts, to accommodate different installation preferences.
