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

The Silent Wings 4 140mm PWM high-speed delivers exceptional performance without compromising on quiet operation. Engineered with optimized fan blades and a funnel-shaped frame, this 140mm fan achieves 1900RPM while maintaining a noise level of just 29.3dB(A). The design features minimal tip clearance between blades and frame, generating 2.36mm H2O air pressure for demanding cooling applications on radiators and heat sinks.

Advanced 6-Pole Motor Technology

The 6-pole fan motor with 3-phase technology reduces power consumption to 4.8W while minimizing vibrations for smooth operation. Combined with the fluid-dynamic bearing (FDB), the Silent Wings 4 achieves virtually inaudible performance at mid-speed and an exceptional lifespan of up to 300,000 hours. This bearing technology significantly reduces vibrations compared to standard sleeve bearings, ensuring long-term reliability.

Dual Mounting System

Two mounting options accommodate different installation scenarios. The pre-installed anti-vibration mounting with push pins reduces noise-generating vibrations for case installations. The included hard plastic mounting provides secure attachment to radiators and heat sinks. Both systems include 4 screws and 4 push pins, offering flexibility for various cooling configurations.

Performance Specifications

At 100% PWM and 12V, the fan delivers 78.4 CFM (133.20 m³/h) airflow with 2.36mm H2O static pressure. The 4-pin PWM connector enables precise speed control from 5-13.2V DC, drawing 0.40A current. The 500mm sleeved cable provides ample reach for most PC builds. Dimensions measure 140 x 140 x 25mm with a weight of 220g including cables.

All-Black Design

The all-black frame and blades feature a high-grade fan sticker for a premium appearance. Whether mounted as a case fan or on radiators, the Silent Wings 4 maintains a clean aesthetic from all viewing angles. The black design integrates seamlessly into modern PC builds without RGB lighting.

Warranty and Certifications

Backed by a 5-year manufacturer warranty and certified with CE, RoHS, RU, UKCA, TUV, and WEEE approvals. Article number BL097.

NO COMPROMISE SILENCE AND PERFORMANCE
Equally quiet and performant operation
Silent Wings 4 140mm PWM high-speed 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 140mm PWM high-speed a fan that makes no compromises between very quiet operation and highest performance.

OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum tolerances for maximum air pressure
Silent Wings 4 140mm PWM high-speed 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 140mm PWM high-speed allows the user to run even the most demanding applications.

DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings 4 140mm PWM high-speed 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 29.3dB(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 140mm PWM high-speed.

ELEGANT LOOK
Magnificent appearance from all angles
Be it as a radiator fan or in the case: Silent Wings 4 140mm PWM high-speed 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 140mm PWM high-speed a high performant and an incredibly good-looking fan.
