be quiet! SilentWings 3 120mm PWM High-Speed (120x120x25mm)

Virtually silent, extraordinary cooling

be quiet! SilentWings® fans are known for their cutting-edge technology, virtually silent operation, and extraordinary cooling power. The third generation of this multiple-award-winning fan series offers unparalleled and uncompromising performance with many intelligent optimisations: a high-quality 6-pole motor, a durable fluid dynamic bearing, unique airflow-optimised fan blades, as well as a rubberised fan frame with funnel-shaped air intakes.

The SilentWings® 3 120mm PWM high-speed model produces extremely high air pressure, making it especially well-suited for use in high-performance water- and air-cooling systems.  

Performance Features

Virtually Silent Operation

• Good balance between volume and power with 28.6dB(A) at 2,200 RPM
• 6-pole motor with three phases for very low power consumption and quiet, nearly vibration-free operation
• Cutting-edge fluid dynamic bearing ensures a lifespan of up to 300,000 hours
• Seven fan blades with optimised surface structure ensure excellent airflow
• The rubberised fan frame is equipped with funnel-shaped air intakes for extremely high air pressure
• Removable anti-vibration attachments minimise vibrations transferred to the PC case and surrounding components
• High-quality IC motor control reduces electronic sounds

Additional PWM Functionality

• Using Pulse Width Modulation (PWM), the fan speed can be intelligently controlled with 4-pin fan controllers (including those installed on many motherboards)
• With the PWM, the system can ramp up the cooling as needed or run with maximum quietness during low-usage times
