be quiet! Silent Wings 4 PWM Fan, Fluid Dynamic Bearing, 140mm, White

This 140mm component fan is engineered to provide focused cooling for demanding system configurations, maintaining a balance between acoustic output and air movement. The fan incorporates Fluid Dynamic Bearing (FDB) technology, specified to deliver reliable operation and rated for a Mean Time Between Failures (MTBF) of 300,000 hours. Rotational speed control is managed via a 4-pin Pulse Width Modulation (PWM) connector, allowing the system to dynamically adjust the fan speed.

The operational range for the rotational speed extends from 0 RPM up to a maximum of 1100 RPM, depending on the thermal demand detected by the system. At maximum speed, the fan achieves an airflow of 51.3 CFM (87.2 m³/h) and generates a static pressure of 0.92 mmH2O, which facilitates effective cooling for components mounted behind restrictive elements like radiators or dense dust filters. Noise output is contained, peaking at 13.6 dB during maximum operation, ensuring the fan contributes minimally to overall system noise.

The unit requires 12 V of power and draws a rated current of 0.3 A, resulting in a typical power consumption of 3.6 W. Its dimensions are 140 mm x 140 mm with a standard 25 mm thickness, making it compatible for installation in cases, radiators, and heatsinks designed for 140mm mounts. Included mounting hardware supports immediate installation.
