140mm PWM


Light Wings 140mm PWM offers impressive illumination for a vibrant unique look, strong performance and quiet operation with efficient cooling.

•    ARGB lighting on front and rear
•    Multiple colors and modes for an individual look thanks to 20 LEDs
•    Seven silence-optimized fan blades for high airflow and low noise-generating turbulences
•    Very quiet operation with max. 23.3dB(A)
•    Long life rifle-bearing gives an operating lifetime of 60,000 hours
•    Three-year manufacturer’s warranty

If you are looking for a quiet case fan with an impressive look from every angle, Light Wings 140mm PWM is your fan of choice.


Lots of illumination possibilities

Light Wings 140mm 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. 20 ARGB LEDs give you many opportunities to individualize your PC build.


Fan blades optimized for high airflow

With optimization for maximum airflow, Light Wings 140mm 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 140mm 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 23.3dB(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 140mm 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.
