Product information

Description

be quiet! SILENT WINGS 4 120mm PWM White is a 120 mm case fan engineered to combine extremely low noise with high cooling performance. The fan features a 6-pole motor, rifle bearing and optimized blade geometry to deliver up to 1600 RPM, an airflow of 82.7 m³/h and a maximum static pressure of 1.79 mmH2O while maintaining quiet operation. Its white finish suits modern PC builds and the operating voltage range (5–13.2 V) ensures compatibility with a variety of setups.

Advantages

The 6-pole motor and rifle bearing increase efficiency and longevity while reducing operational noise. Anti-vibration mountings help minimize chassis-transmitted vibrations. The fan blades are shaped to maximize airflow and static pressure within a compact 120 mm form factor, providing effective cooling for high-end systems without compromising acoustic performance.

Suitable for

Cooling PC cases in mid-tower and compact builds
Intake or exhaust ventilation in desktops
Supplementary cooling for radiators and GPU/CPU airflow optimization

How to use

Install the fan in the desired orientation for intake or exhaust using the supplied anti-vibration mountings or standard screws. Connect the PWM cable to a motherboard header or a compatible fan controller to allow automatic speed regulation according to system temperature. Ensure sufficient clearance inside the case and route cables to avoid contact with the blades.

Usage recommendations

For best results, configure the motherboard fan control to allow PWM regulation so the fan can balance noise and performance automatically; periodically check for dust buildup and clean the blades to maintain airflow and longevity.

Maximum speed	1600 RPM	1600 RPM	1600 RPM	2500 RPM	3000 RPM	1900 RPM	Higher RPM increases cooling performance but may result in higher noise levels.
Airflow	82.7 m³/h	82.74 m³/h	82.74 m³/h	130.31 m³/h	142.5 m³/h	133.2 m³/h	Higher airflow rates cool demanding components more effectively in dense builds.

◎ The suitability and use cases comparison helps identify which model best matches specific requirements for aesthetics, noise level, and cooling performance.

Use case	Recommended product	Why
Light-themed PC build with a balance of quietness and cooling	Fan be quiet! SILENT WINGS 4 120mm PWM White	Combines a white finish, PWM control, and comfortable performance for standard PC cases.
Classic black PC build focused on quiet operation	Fan be quiet! SILENT WINGS 4 120mm PWM	Offers the same balanced performance and PWM control as the white version but in a black design.
Setups without need for precise speed control	Fan be quiet! SILENT WINGS 4 120mm	Suitable for users who do not require PWM speed management.
Maximum cooling performance in a black case	Fan be quiet! SILENT WINGS 4 120mm PWM high-speed or SILENT WINGS PRO 4	Provides significantly higher airflow and pressure for high-demand setups.
Cooling for a larger light-themed case	Fan be quiet! SILENT WINGS 4 140mm PWM high-speed White	Combines a white finish with a larger 140 mm format for higher airflow capacity.

The Fan be quiet! SILENT WINGS 4 120mm PWM White differs from alternatives primarily through its distinct white colour while retaining the balanced specifications of the standard 1600 RPM PWM model. It is most suitable for users building a white-themed PC who value quiet operation paired with automatic speed control. Higher-speed models should be chosen only when maximum airflow is strictly required for extreme workloads, whereas other alternatives suit black colour preferences or different size requirements.
