be quiet! Silent Wings 4 120mm PWM Fan - Premium Performance Cooling

The Silent Wings 4 120mm PWM combines virtually inaudible operation with exceptional cooling performance for demanding PC builds. Engineered with advanced 6-pole motor technology and fluid-dynamic bearing, this fan delivers 1600RPM performance at just 18.9dB(A), making it ideal for high-end systems requiring both power and silence.

Advanced Cooling Technology

Featuring optimized fan blades with minimal tip clearance and funnel-shaped air outlets, the Silent Wings 4 generates 1.79mm H2O air pressure and 48.7 CFM airflow. This design ensures maximum cooling efficiency on heat sinks, radiators, and case installations. The 6-pole motor with 3-phase technology reduces vibration while consuming only 1.44W of power, delivering smooth operation across the entire 5-13.2V operating range.

Exceptional Build Quality

The fluid-dynamic bearing (FDB) technology provides an industry-leading lifespan of up to 300,000 hours while significantly reducing operational vibrations. The all-black design features a high-grade fan sticker, black frame, and black blades for a sleek aesthetic in any system. At 190g with a 500mm sleeved cable and 4-pin PWM connector, installation is straightforward with included mounting options.

Flexible Mounting Solutions

Two mounting options accommodate different applications: pre-installed anti-vibration rubber mounting for case installations minimizes noise-generating vibrations, while hard plastic mounting provides secure attachment to radiators and heat sinks. Both solutions include 4 screws and 4 push pins for versatile installation.

NO COMPROMISE SILENCE AND PERFORMANCE
Equally quiet and performant operation
Silent Wings 4 120mm PWM is the fan of choice for all possible operations. Be it in a case, on radiators or heat sinks – Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 120mm PWM a fan that makes no compromises between virtually inaudible operation and high performance.

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

DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings 4 120mm PWM has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed.

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 18.9dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated
in mid-speed.

FLUID-DYNAMIC BEARING
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 4 120mm PWM.

ELEGANT LOOK
Magnificent appearance from all angles
Be it as a radiator fan or in the case: Silent Wings 4 120mm PWM always makes a good impression. The all-black design combined with the high-grade fan sticker makes the fan shine in any system. This makes
Silent Wings 4 120mm PWM a high performant and an incredibly
good-looking fan.
