Three Light Wings 140mm PWM offer impressive illumination for a vibrant unique look strong performance and quiet operation with efficient cooling.   Three fans included ARGB lighting on front and rear Multiple colors and modes for an individual look thanks to 20 LEDs ARGB Hub allows synchronization of up to six ARGB components Seven silence-optimized fan blades for high airflow and low noise-generating turbulences Very quiet operation with max. 23.3dB(A) Impressive Lighting 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.     Three Fans One Hub Synchronize up to six Light Wings simultaneously An ARGB Hub allows to use and synchronize 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.     Perfect Case Fan 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.     Very Quiet Operation Acclaimed be quiet! low noise level A highly optimized fan frame and impeller achieve the silent operation be quiet! is famous for. With a noise level of just 23.3dB(A) at maximum fan speed it proves that instead of being a replacement the lighting is an addon to very silent and very powerful operation. All features combine to make Light Wings 140mm PWM the fan of choice for silent show cases and gaming systems alike.     Variable Fan Speed Function 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.
