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

The be quiet! Silent Wings 4 BL092 is a 120 mm fan engineered for low-noise operation and consistent airflow within a PC chassis. It incorporates a 6-pole motor designed to reduce vibration and power consumption, contributing to smoother performance. The fan is constructed with a fluid-dynamic bearing (FDB), a component selected for its long operational lifespan and quiet running characteristics. Its blades are shaped to optimize airflow efficiency for cooling system components.

This model operates at a maximum rotational speed of 1600 RPM, producing up to 48.7 CFM of airflow and a static pressure of 1.79 mmH2O. This balance of airflow and pressure makes it suitable for use as a case fan for general ventilation or mounted on heatsinks and radiators where greater resistance is present. At full speed, the fan's noise output is rated at 18.9 dBA. It connects via a standard 3-pin DC header and includes voltage-step-down adapters to enable lower, quieter speed settings.
