be quiet! Silent Wings 4 120mm PWM High Speed Fan BL094
The be quiet! Silent Wings 4 120mm PWM High Speed Fan is designed for users who need high-performance cooling without the noise—combining optimized blade geometry and low-vibration design for systems running demanding applications. It delivers significant air pressure through a compact frame while operating at a maximum of 31.2 dB(A), making it suitable for both case intake and radiator duties.
Why this product
High-pressure airflow in compact form
Small blade-to-frame clearance and funnel-shaped outlets concentrate airflow into 3.96 mmH₂O static pressure, delivering performance on heat sinks and radiators where standard fans fall short.
Noise stays under 32 dB at full speed
A 6-pole motor with 3-phase design reduces vibration and power draw, keeping operation nearly inaudible even under load.
Includes both mounting styles
Ships with pre-installed rubber anti-vibration mounts for cases and plastic screw mounts for radiators and heatsinks, so mounting fits your application without buying extras.
300,000-hour fluid-dynamic bearing
Advanced FDB technology supports exceptionally long service life while further dampening vibration.

- Rated for 5–13.2 V operation; confirm your fan controller or power supply delivers PWM-compatible voltage within this range.
Best for
- Radiator and heatsink cooling where static pressure matters
- Systems requiring both high airflow and quiet operation at mid-speed
- Users running sustained workloads and preferring fanless-like silence
- All-black builds where aesthetics and performance both count
Trade-offs
- Budget-constrained builds where cost per CFM is the primary metric
- Systems needing airflow above 76.7 CFM; this fan maxes out there
- AC-powered or non-PWM cooling setups; it requires PWM control
Silent Wings 4 120mm 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 120mm PWM high-speed a fan that makes no compromises between very quiet operation and highest performance.
Silent Wings 4 120mm 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 120mm PWM high-speed allows the user to run even the most demanding applications.
Silent Wings 4 120mm 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 with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 31.2dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.
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 high-speed.
Be it as a radiator fan or in the case: Silent Wings 4 120mm 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 120mm PWM high-speed a high performant and an incredibly good-looking fan.
