Be quiet! Silent Wings 4 PRO 120mm PWM
The Be quiet! Silent Wings Pro 4 120mm PWM fan delivers high performance, quiet operation and a wide range of uses. Thanks to its newly designed blades, which are optimised for efficient airflow, and the minimal gap between the blades and the frame, it achieves excellent air pressure even at lower speeds. The funnel-shaped outlet also improves airflow direction. The fan uses a 6-pole motor with a fluid dynamic bearing, which ensures smooth operation and a long lifespan. A speed switch lets you easily adapt the performance to your current cooling needs.
Key features of the Be quiet! Silent Wings 4 PRO 120mm PWM

- Minimal gap between blades and frame and a funnel-shaped outlet for better air pressure
- Very quiet operation at normal speeds
- 6-pole motor and Fluid Dynamic Bearing ensure quiet and smooth operation
- Three mounting options – case, radiator and universal use
- All-black design with high-quality cable sleeving
- Long lifespan of up to 300000 hours
6-pole motor and fluid dynamic bearing
The 6-pole motor of the Be quiet! Silent Wings 4 PRO 120mm PWM fan operates in three phases, which reduces vibrations and energy consumption. This results in smooth, quiet operation with a noise level of up to 36.9dB(A). The advanced Fluid Dynamic Bearing ensures high durability, extends the lifespan to 300000 hours and helps to dampen mechanical vibrations. The combination of these elements gives the fan long-term stable and reliable performance.
Optimised for high air pressure
The reduced distance between the blades and the frame helps to increase air pressure, making it ideal for use in builds where effective heat dissipation is a priority. This design of the Be quiet! Silent Wings 4 PRO 120mm PWM fan helps to keep component temperatures lower even during demanding applications and guarantees stable system operation without excessive noise.
Speed switch
The Be quiet! Silent Wings 4 PRO 120mm PWM fan is equipped with a switch that lets you choose between three performance levels – medium, high and ultra-high. This lets you easily set the mode according to your requirements, from economical quiet operation for everyday use to maximum performance for intensive cooling.
Mounting options
The package includes three types of mounting corners for easy installation depending on the specific use. The anti-vibration corners are designed for mounting in a PC case and dampen transferred vibrations. The solid corners are optimised for radiators and provide a secure fit. The plastic mounts serve as a universal solution for standard applications. A high-quality insulated PWM cable makes handling easier.
