be quiet! SILENT WINGS 4 120mm Fan Black

be quiet! Silent Wings 4 | High-Performance PC Fan

The be quiet! Silent Wings 4 120mm PWM high-speed fan delivers exceptional cooling performance while maintaining near-silent operation. Designed for demanding PC builds where both airflow and noise reduction matter, this 120mm case fan combines advanced engineering with premium build quality to create the ideal cooling solution for high-end systems.

Key Specifications

Near-Silent Performance at High Speed

Despite its impressive 2500 RPM maximum speed, the Silent Wings 4 maintains remarkably quiet operation at just 31.2 dB. This is achieved through be quiet!’s advanced anti-vibration mounting system and precision-engineered fan blades that optimise airflow while minimising turbulence. The fluid dynamic bearing ensures smooth, quiet rotation throughout the fan’s extended 300,000-hour lifespan.

Advanced PWM Control for Intelligent Cooling

The 4-pin PWM connector provides precise speed control, allowing your motherboard to adjust fan speed based on system temperature. This intelligent cooling management means the fan runs at minimal speeds during light workloads, virtually eliminating noise, then ramps up automatically when your system needs maximum cooling. The 6-pole motor delivers consistent performance across the entire speed range without sacrificing efficiency.

Maximum Airflow for Demanding Systems

With an impressive airflow rating of 130.31 m³/h and maximum air pressure of 3.96 mmH2O, this fan moves substantial volumes of air through your case. The aerodynamic fan blades are specifically designed to maximise static pressure, making it equally effective for both intake and exhaust configurations. Whether cooling your CPU heatsink or maintaining positive case pressure, the Silent Wings 4 delivers reliable performance where it matters most.
