The be quiet! Silent Wings 4 120 mm PWM high-speed fan delivers a combination of exceptionally quiet operation and top-tier performance for demanding builds. Thanks to its aerodynamic blades, funnel-shaped frame, and 6-pole motor, it offers high static pressure, minimal vibrations, and a long lifespan up to 300,000 hours.
Optimized blades and flared frame for maximum pressure

Optimized blades and flared frame for maximum pressure

Aerodynamically shaped blades combined with a funnel-shaped frame increase airflow and static pressure—ideal for dense heatsink fins and radiators.

Quiet and smooth operation thanks to the 6-pole motor

Quiet and smooth operation thanks to the 6-pole motor

The three-phase 6-pole motor reduces vibrations and power consumption, ensuring smooth and quiet operation up to about 31.2 dB(A).

Long service life with hydrodynamic bearing

Long service life with hydrodynamic bearing

Advanced FDB bearings provide a lifespan of up to 300,000 hours and consistent performance even under demanding operation.

Silent Wings 4 120 mm PWM high-speed is a versatile fan for cases, heatsinks, and radiators. Optimized blades and a funnel-shaped frame deliver maximum airflow and air pressure at very low noise levels, so you won’t have to compromise between quiet operation and performance.

Thanks to the minimal gap between blades and frame, the fan achieves excellent static pressure—ideal for dense fin stacks and liquid-cooling radiators. Anti-vibration mounts (push-pin or screws) further reduce vibration transfer. The 6-pole, three-phase motor lowers power draw and ensures smooth operation up to about 31.2 dB(A).

The hydrodynamic bearing (FDB) guarantees a long lifespan up to 300,000 hours and stable performance. The sleek all-black design with a quality finish fits perfectly into any modern PC build.

  • High static pressure for radiators and heatsinks
  • Quiet operation even at high RPM
  • Anti-vibration mounting for minimal noise
  • 6-pole motor and FDB bearings for reliability and long endurance
