Case fan be quiet! SILENT WINGS PRO 4 120mm PWM

be quiet! SILENT WINGS PRO 4 120mm PWM

Silent Wings Pro 4 120mm PWM is be quiet's most advanced, productive and versatile fan yet!

Optimized fan blades for maximum performance with cooler radiators and HVAC systems
Switch allows you to change the maximum PWM speed with medium-speed, high-speed and ultra-high-speed modes (up to 3000 RPM)
Reduced clearance between blades and fan frame with funnel-shaped outlet for very high air pressure
Virtually silent operation at rated speed
6-pole fan motor and hydrodynamic bearing for reduced vibration and very smooth operation
Various mounting systems for use as a case fan or with a radiator

Innovative blades for a new level of performance
The blades are the key element of a fan. Therefore, the blades of the Silent Wings Pro 4 120mm PWM fan have been designed from the ground up to deliver significantly higher performance for all possible usage scenarios: as a case fan, as well as with heatsinks for coolers and HIDs.

Minimal clearance for maximum air pressure
The Silent Wings Pro 4 120mm PWM provides very high air pressure and therefore significantly increases the performance of the cooling system. The high level of air pressure is achieved by a reduced gap between the fan blades and the fan frame, allowing the Silent Wings Pro 4 120 mm PWM to guarantee reliable PC cooling even in the most demanding programs.

3 modes for all usage scenarios
The speed switch allows you to quickly and easily switch between medium, high-speed and ultra-high-speed maximum PWM (PWM) modes. Medium speed is suitable for most applications requiring consistent cooling performance. High-speed provides more cooling power, while ultra-high-speed mode guarantees maximum speed for cooling the most demanding hardware in high-performance PC builds.

Key to virtually silent operation
the 6-pole fan motor with 3 phases ensures very low power consumption, less vibration and therefore quiet operation with max. 36.9 dB(A). Thanks to this advanced technology, the fan is virtually silent when running at medium speed.

For different purposes
The Silent Wings Pro 4 120mm PWM comes with 3 different mounting options. The radiator mounts installed initially were specifically designed to maximize compatibility and performance in high-end cooling systems. For using the fan as a case fan, it is better to use the special anti-vibration supports as they minimize vibrations. A set of plastic mounts is also present.

For a very long service life
The advanced hydrodynamic bearing (FDB) ensures an extremely long fan life of up to 300,000 hours. In addition, it significantly reduces vibrations and ensures that the Silent Wings Pro 4 120 mm PWM is virtually silent.

Attractive in every detail
The all-black design combined with the stylish fan center sticker makes the Silent Wings Pro 4 120mm PWM the highlight of any system. The black braided cable perfectly complements the look of the fan and, in addition, its connector has been redesigned for user-friendly connectivity and a more attractive look.
