Product information

Description

be quiet! SILENT WINGS 4 140mm PWM White is a 140 mm case fan designed to combine very low noise with effective airflow. It features a 6-pole motor, rifle bearing and anti-vibration mountings. With dimensions of 140 x 140 x 25 mm and a white finish, this fan is intended for high-end PC builds that require quiet but reliable cooling.

Advantages

The 6-pole motor and optimized blade geometry provide stable airflow at a maximum rotational speed of 1100 RPM while keeping acoustic output minimal. Anti-vibration mountings reduce structure-borne noise and the rifle bearing offers long-term durability. The fan delivers up to 87.2 m³/h airflow and a maximum air pressure of 0.92 mmH2O, making it suitable for constrained spaces inside a case.

Suitable for

CPU and case ventilation in compact or full-size desktop PCs
Quiet high-end systems where low noise is a priority
Cases requiring a 140 mm fan with PWM speed control
