be quiet! Silent Wings Pro 4 120mm PWM - Professional Performance Cooling

The Silent Wings Pro 4 120mm PWM represents be quiet!'s most advanced fan technology, engineered for users demanding both exceptional cooling performance and minimal noise. This 120mm fan delivers up to 3000RPM with a remarkably quiet 36.9dB(A) operation at maximum speed.

Advanced Fan Blade Design

The fan blades have been completely redesigned from the ground up, featuring an optimized arrangement that maximizes performance across all applications. The minimal tip clearance between blades and frame creates extraordinary air pressure of 5.31mm H2O, making this fan exceptionally effective on radiators and heat sinks where static pressure matters most. The funnel-shaped air outlet further enhances airflow efficiency, delivering 83.9 CFM (142.5 m³/h) at full speed.

Three-Speed Flexibility

The integrated speed switch provides three distinct maximum RPM settings: medium-speed for standard cooling needs with virtually inaudible operation, high-speed for demanding workloads, and ultra-high-speed (3000RPM) for extreme cooling requirements in high-end systems. This versatility ensures optimal performance regardless of your build's thermal demands.

Premium Motor Technology

Equipped with a 6-pole fan motor utilizing 3-phase technology, the Silent Wings Pro 4 achieves lower power consumption (3.6W), reduced vibration, and smoother operation compared to traditional 4-pole designs. The fluid-dynamic bearing (FDB) extends operational lifespan to an impressive 300,000 hours while further minimizing vibrations and noise.

Versatile Mounting Solutions

Three mounting options come included: pre-installed radiator corners optimized for liquid cooling setups, anti-vibration mounts for chassis installation that eliminate resonance, and standard plastic mountings for universal compatibility. This comprehensive package ensures proper installation for any configuration.

Professional Build Quality

The all-black design features a premium sleeved 500mm PWM cable with an easy-connect 4-pin connector. Operating voltage ranges from 7-13.2V DC with 0.30A current consumption. The fan weighs 227g and measures 120 x 120 x 25mm, fitting standard 120mm mounting points. Backed by a 5-year manufacturer warranty and certified with CE, RoHS, TUV, UKCA, and WEEE compliance.

IMPROVED ON ALL LEVELS
Altered blade arrangement for new generation performance
The fan blades are what makes a fan. It is for this reason that the fan blades of Silent Wings Pro 4 120mm PWM have been developed newly from scratch. The new blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks.

OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum distance for maximum air pressure
Silent Wings Pro 4 120mm PWM makes for extraordinary air pressure and therefore, significantly increases the system's performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 120mm PWM allows the user to run even the most demanding applications.

SPEED SWITCH
3 speed options for any possible application
The speed switch makes switching between medium, high-speed and ultra-high-speed of maximum RPM levels quick and easy. The Silent Wings Pro 4 120mm PWM alters its application with a simple slide to the right. Medium-speed is suitable for any operation that requires regular cooling performance. High-speed lets the fan spin faster, providing more cooling power. Ultra-high-speed ultimately offers enough rpm to cool even the most demanding hardware in high-end PC builds.

6-POLE FAN MOTOR
The key for virtually inaudible operation when needed
6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 36.9dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.

3 DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings Pro 4 120mm PWM has 3 mounting options in the scope of delivery. The pre-installed radiator corners are specially designed for radiators on which the incomparable performance of this high-end fan completely shines. On the other hand, for chassis use, the anti-vibration mounting is the first choice as they reduce vibrations to a minimum. The plastic mountings round up the scope.

FLUID-DYNAMIC BEARING
For a sustainable operation
The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings Pro 4 120mm PWM.

ELEGANT LOOK
Magnificent appearance in all details
The all-black design combined with a high-grade fan sticker makes Silent Wings Pro 4 120mm PWM a highlight in any system. The finely sleeved PWM cable perfectly rounds up the outer appearance of the fan. Not only does the PWM cable look great: its connector can also be plugged in and out with ease, making the fan an eye-catcher and user-friendly alike.
