Product information

Description

The be quiet! SILENT WINGS 4 140mm PWM high-speed is a 140 mm case fan engineered for a balance of low noise and high cooling performance. Featuring a 6-pole motor, Fluid Dynamic Bearing (FDB), and blades optimized for maximum airflow, this fan reaches up to 1900 RPM with an airflow of 133.2 m³/h and a maximum static pressure of 2.36 mmH2O. Its operating voltage range (5–13.2 V) and sleek black design make it suitable for high-end systems and various mounting locations.

Advantages

The combination of a 6-pole motor and Fluid Dynamic Bearing provides quiet operation and long service life while maintaining high rotational stability. Anti-vibration mountings reduce transfer of vibration to the chassis and the optimized blade geometry increases airflow and static pressure for demanding cooling tasks. The PWM control allows precise speed adjustment, and the compact 140 mm form factor integrates into most cases without visual disruption.

Suitable for

High-performance CPU or GPU cooling in desktop systems
Radiator and liquid-cooling loops requiring high static pressure
Case ventilation in compact and full-size enclosures
Systems where low noise and long-term reliability are important

How to use

Install the fan into the case, radiator, or mounting bracket using the supplied anti-vibration mountings or appropriate screws, ensuring airflow direction matches the intended intake or exhaust configuration. Connect the PWM cable to a compatible 4-pin header on the motherboard or fan controller to enable automatic speed regulation. Adjust fan curves in BIOS or fan-control software if required to balance noise and cooling performance.

Usage recommendations

For radiator or restricted airflow setups, orient the fan so the blade geometry faces the heat source to maximise static pressure. Regularly check and clean the blades to maintain airflow and inspect anti-vibration mountings for secure fitment. Use PWM control to reduce noise during low-load periods while allowing full speed when higher cooling capacity is needed.
