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

Key specifications

  • Type: Fan
  • Fan diameter: 140 mm
  • Dimensions: 140 x 140 x 25 mm
  • Maximum speed: 1100 RPM
  • Maximum airflow: 87.2 m³/h
  • Maximum air pressure: 0.92 mmH2O
  • Bearing: Rifle bearing
  • Voltage range: 5–13.2 V
  • Colour: White
  • Weight: 0.22 kg

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.

Usage 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.
