Lots of illumination possibilities

Light Wings 120mm PWM 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. 18 ARGB LEDs give you many opportunities to individualize your PC build.


Fan blades optimized for high airflow

With optimization for maximum airflow, Light Wings 120mm PWM is the right choice for any case configuration that demands high cooling performance. Its seven airflow-optimized fan blades not only reduce noise-generating turbulences but also ensure Light Wings 120mm PWM provides the performance that is needed, even in demanding configurations.


Acclaimed be quiet! low noise level

A highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 20.6dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to very silent and powerful operation. All features combine to make Light Wings 120mm PWM the fan of choice for silent show cases and gaming systems alike.


Adjusts the fan speed and associated noise level

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.

“It was our goal from scratch not only to build an ARGB fan, but one that holds up to the high standards we have at be quiet! And the results speak for themselves: years of development pay off with this performant and silent fan, which is the very first ARGB fan of be quiet!”
