## Long description

The be quiet! SILENT WINGS 4 140mm PWM fan is a high-performance cooling solution engineered for users who prioritize both silence and efficiency in their PC builds. This 140mm fan utilizes a sophisticated 6-pole motor and advanced fan blade geometry to ensure optimal airflow while maintaining near-silent operation, making it an ideal choice for high-end computer systems.
Advantages
The primary benefit of this fan is its exceptional balance between cooling performance and acoustic comfort. By incorporating Fluid Dynamic Bearing technology, the fan achieves a significantly longer lifespan and reduced mechanical noise compared to standard sleeve or ball-bearing fans. The inclusion of anti-vibration mountings further minimizes noise transfer to the computer case, ensuring a stable and quiet environment even under load.
Suitable for
High-end PC cases requiring efficient airflow
Silent workstation builds
Systems where low noise levels are critical
General case cooling for improved component longevity
This fan may not be suitable for applications requiring extremely high static pressure, such as thick liquid cooling radiators or dense heatsinks, where higher RPM models might be necessary. Additionally, it is not intended for industrial environments or non-standard cooling configurations that require specific proprietary connectors.
Key specifications
Fan diameter: 140 mm
Rotational speed: 1100 RPM
Airflow: 87.16 m³/h
Air pressure: 0.92 mmH2O
Bearing type: Fluid Dynamic Bearing
Voltage range: 5 - 13.2 V
Color: Black
To use the fan, mount it to your computer case or cooling component using the provided anti-vibration mounting hardware. Connect the 4-pin PWM cable to the corresponding header on your motherboard. Once installed, you can configure the fan speed curve through your motherboard BIOS or system software to match your specific cooling requirements and noise preferences.
What to consider before purchase
Ensure your case has sufficient clearance for a 140mm fan
Verify that your motherboard has an available 4-pin PWM fan header
Check if your cooling setup requires higher static pressure for radiators
For optimal performance, ensure the fan is installed with the airflow direction facing out of the case for exhaust or into the case for intake, and regularly clean the blades to prevent dust accumulation that could affect acoustic performance.
