Product information

Description

be quiet! SILENT WINGS 4 140mm PWM high-speed White is a 140 mm high-speed cooling fan engineered for efficient airflow and low noise. It features a rifle bearing, a 6-pole motor and anti-vibration mountings. With a maximum speed of 1900 RPM, the fan achieves up to 133.2 m³/h airflow and a maximum static pressure of 2.36 mmH2O, and operates across a voltage range of 5–13.2 V. The white finish suits modern PC cases and high-end system builds.

Advantages

The combination of a 6-pole motor, optimized fan blades and anti-vibration mountings reduces operational noise while maintaining high airflow and pressure. The rifle bearing provides durability and smooth rotation. PWM control allows precise speed adjustment for balancing cooling performance and acoustics. The white colour offers a clean aesthetic for case integration.

Suitable for

  • High-performance gaming PCs requiring strong case airflow
  • Workstations and render farms with sustained cooling demands
  • Radiator or case fan installations where high static pressure is beneficial
  • Systems where a white fan aesthetic is preferred

  • Maximum rotational speed: 1900 RPM
  • Airflow: 133.2 m³/h
  • Maximum static pressure: 2.36 mmH2O
  • Bearing type: rifle bearing
  • Operating voltage: 5–13.2 V
  • Product colour: White
  • Weight: 0.22 kg
  • MPN: BL117
  • EAN: 4260052191088

How to use

Install the fan in the desired position in the PC case or on a radiator using the supplied mounting hardware or standard fan screws. Connect the PWM cable to an appropriate motherboard fan header or fan controller to enable automatic speed regulation. Configure fan curves in BIOS or software to match thermal and acoustic requirements. Ensure correct airflow direction when mounting (typically arrow indicators on the fan frame).

Usage recommendations

For optimal balance between noise and cooling, use PWM control with a custom fan curve: keep idle speeds low and allow higher RPM under sustained CPU/GPU load. When installing on radiators, ensure adequate spacing and consider push-pull configurations for improved cooling performance.
