120 mm ARGB case fan

The be quiet! Light Wings 120 mm PWM fan fits standard 120 mm mounting points and adds addressable RGB lighting on both sides of the frame. It is built for PC builders who want visible illumination without sacrificing low-noise operation. The black finish suits dark-themed builds.

PWM speed control and noise

A 4-pin PWM connector lets the motherboard regulate speed between 1600 and 1999 RPM, delivering 40 to 45 CFM of airflow at a maximum of 20.6 dBA. The rifle bearing is rated for 60 000 hours of continuous running. This specification decides whether the fan meets your thermal and acoustic targets.

18 ARGB LEDs and motherboard sync

Eighteen addressable LEDs on the front and rear rings create uniform lighting that can be synchronised through a standard 5 V ARGB header. No separate controller is included, so the motherboard or an external ARGB hub must provide the signal and power for the effects.

Questions about this item

How loud is the 20.6 dBA maximum noise level once the fan is installed in a case?

At 20.6 dBA the fan is barely audible inside a closed chassis and will not raise the overall system noise floor in a typical build.

What does the 4-pin PWM connector allow the motherboard to control?

The 4-pin PWM header lets the motherboard vary speed precisely between 1600 and 1999 RPM based on temperature curves.

Will the 120 mm by 25 mm frame fit standard case mounts and radiators?

Yes, the 120 mm square footprint and 25 mm thickness match the universal mounting pattern used by virtually all cases and radiators.
