be quiet! Silent Wings 4 140mm PWM High-Speed Fan - White

The Silent Wings 4 140mm PWM High-Speed White fan delivers exceptional cooling performance with near-silent operation for high-end PC systems. Engineered with optimized fan blades and advanced bearing technology, this fan achieves 77.57 CFM airflow while maintaining just 29.3 dB(A) noise levels at 1600 RPM maximum speed.

Advanced Cooling Performance

The fan's optimized blade design with small tip clearance and funnel-shaped air outlets generates extremely high air pressure, making it ideal for demanding applications on radiators and heat sinks. Operating at 1600 RPM, the 140mm fan moves substantial airflow while the 6-pole motor reduces vibration for smooth, stable operation.

Premium Build Quality

Equipped with a fluid-dynamic bearing, the Silent Wings 4 achieves a super-long lifespan of up to 300,000 hours of continuous operation. The bearing technology ensures consistent performance and reliability for years of use. The fan draws just 2.16W of power from its 12V 4-pin PWM connector, providing efficient operation with precise speed control.

Flexible Installation

Anti-vibration mounting hardware includes both push pins and screwed installation options, allowing secure attachment while minimizing noise transfer to the case. The 140mm x 140mm x 25mm dimensions fit standard 140mm mounting points in cases and radiators.

Clean White Aesthetic

The all-white design complements modern PC builds with a clean, elegant appearance. The white fan shroud integrates seamlessly into white-themed systems without RGB lighting, maintaining a minimalist aesthetic.

Backed by a 5-year manufacturer warranty, the Silent Wings 4 combines German engineering with reliable performance for enthusiast and professional PC builds.
