Be Quiet! Light Wings
Impressive Lighting
Be Quiet Light Wings 120mm PWM high-speed offers ARGB lighting at the front and rear. The subtly lit ring at the back combined with the bright one at the front make for a magnificent appearance from every angle. 20 ARGB LEDs give you many opportunities to individualise your PC build.
Three Fans, One Hub
An ARGB Hub allows to use and synchronise up to six ARGB components at the same time. A user-friendly installation makes for an easy and convenient process, while the elegant all-black design of the ARGB Hub visually suits any PC case. It can be mounted like an SSD or anywhere else using the double-coated adhesive tape supplied.
For Radiators and Heatsinks
With a remarkably high air pressure of up to 2.3mm/H2O, Be Quiet! Light Wings 120mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The nine airflow-optimised fan blades provide enough air pressure to make this fan perfect, even in demanding configurations.
Low Noise Level and Fan Speed Adjustment


Quiet Operation 
A highly optimised impeller achieves the silent operation be quiet! is famous for. With a noise level of 31dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to silent.
All features combine to make Light Wings 120mm PWM high-speed the fan of choice for silent show cases and gaming systems alike.

Variable Fan Speed Function
 Pulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan. With PWM the system can ramp up the cooling when it’s needed, or operate in maximum quiet mode when it’s not.
