be quiet! Silent Wings 4 140mm PWM - Premium Performance Cooling

The Silent Wings 4 140mm PWM delivers professional-grade cooling performance with virtually inaudible operation. Engineered with optimized fan blades and funnel-shaped air outlets, this 140mm fan achieves exceptional air pressure while maintaining whisper-quiet operation at just 13.6dB(A) at full speed.

Advanced 6-Pole Motor Technology

Equipped with a state-of-the-art 6-pole fan motor featuring 3 phases, the Silent Wings 4 operates with minimal vibration and power consumption. The fluid-dynamic bearing (FDB) technology ensures smooth, reliable performance with an extraordinary lifespan of up to 300,000 hours. This advanced bearing system significantly reduces operational vibrations, contributing to the fan's virtually silent performance at mid-speed operation.

Optimized for Maximum Air Pressure

The Silent Wings 4 features precision-engineered fan blades with minimal tip clearance, creating maximum air pressure of 0.92mm H2O. This design delivers 51.3 CFM airflow at 1100 RPM, making it ideal for demanding applications including CPU coolers, radiators, and case ventilation. The funnel-shaped frame outlets further enhance airflow efficiency, ensuring optimal cooling performance across all mounting configurations.

Flexible Mounting Solutions

Two mounting options come included: pre-installed anti-vibration push pins for case installation and traditional screw mounting for radiators and heatsinks. Both mounting systems minimize noise-generating vibrations, ensuring quiet operation regardless of installation method. The 500mm sleeved cable with 4-pin PWM connector provides flexible placement options and clean cable management.
