be quiet! Shadow Wings 2 PWM Fan, Rifle bearing, 140mm, White

This cooling fan is constructed with a 140 mm diameter and is specifically suited for use in standard PC case ventilation roles. The unit operates using Pulse Width Modulation (PWM) support via a 4-pin connector, allowing the rotational speed to be dynamically controlled by the motherboard. Its operational range extends up to a maximum speed of 900 RPM, delivering an airflow volume of 85 cubic meters per hour (m³/h).

The design focuses on acoustic efficiency; at its maximum rated speed, the fan generates a measured noise level of 14.9 dB. Longevity is addressed through the implementation of a rifle bearing system, which results in a Mean Time To Failure (MTTF) rating of 80,000 hours. The fan accepts input voltages between 6V and 12V, with a rated power consumption of 3.6W when operating at 12V, ensuring stable performance across common system requirements.
