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

How to use

Install the fan in a 140 mm mounting position inside the PC case, observing airflow direction indicated on the frame. Connect the PWM cable to a compatible motherboard fan header to allow automatic speed regulation. Secure the fan using the provided screws or anti-vibration mounts and route cables to avoid contact with the blades.

Recommendations

Use the fan on a PWM-enabled header for optimal balance of noise and cooling. For best results, combine intake and exhaust fans to create directed airflow and check periodic dust removal to maintain performance.
