be quiet! SILENT WINGS 4 | 120mm PWM high-speed White Computer case Fan 12 cm 1 pc(s)

be quiet! SILENT WINGS 4 120mm PWM 2500 RPM 130.3 m³/h is a 120 mm case fan engineered to provide high airflow with low noise. With a maximum speed of 2500 RPM and an airflow rating of 130.3 m³/h, this fan is designed for demanding high-performance PC builds. The fan uses a rifle bearing and measures 120 x 120 x 25 mm, making it compatible with standard PC cases; its white finish suits systems where component color is a consideration.

Advantages

The fan combines a high-performance 6-pole motor, anti-vibration mountings and blades optimized for maximum airflow to balance strong cooling capacity with minimal audible disturbance. PWM control allows precise speed regulation, while the rifle bearing enhances durability and quiet operation. Its compact 120 mm form factor ensures broad compatibility.

Suitable for

• High-performance gaming PCs and workstations requiring strong case airflow
• Systems where low noise levels are important (silent or near-silent builds)
• Standard ATX, microATX and mini-ITX cases supporting 120 mm fans
• Cooling setups needing PWM-controlled fans for automatic speed adjustment

Key specifications

• Fan diameter: 120 mm
• Speed: up to 2500 RPM (PWM)
• Airflow: 130.3 m³/h
• Bearing type: rifle bearing
• Dimensions: 120 x 120 x 25 mm
• Colour: White
• Weight: 0.19 kg

How to use

Install the fan in a compatible 120 mm mounting location inside your PC case, aligning the airflow direction as required for intake or exhaust. Connect the PWM cable to a motherboard fan header or fan controller that supports PWM for automatic speed control. Use the included anti-vibration mountings where applicable and ensure cables are routed to avoid obstructing the blades.

Recommendations

For optimal balance of cooling and noise, configure PWM profiles in BIOS or fan-control software to allow the fan to run at lower speeds under light load and increase toward the 2500 RPM range under high CPU/GPU load. Regularly clean dust from the blades and filter areas to maintain airflow and prolong bearing life.
