IMPOSING INITIATION Light Wings 140mm PWM offers ARGB back and forth lighting. Subtlely illuminated ring at the back in combination with bright at the front form a wonderful look at every angle. 20 ARGB LEDs give you many possibilities to individualize your computer. IDEAL CONSTRUCTOR With optimization for maximum airflow, Light Wings 140mm PWM is the right choice for any housing configuration that requires high cooling efficiency. Seven air-optimised fan blades not only reduce noise-generating turbulence, but also make Light Wings 140mm PWM provide sufficient performance, even in demanding configurations. Very Silent Work The highly optimised rotor provides a quiet job from which it is famous for being quiet! With noise level 23.3 dB(A) at maximum fan speed, it proves that the backlight is an addition to very quiet and efficient operation. All these features make Light Wings 140mm PWM the best choice for quiet enclosures and gaming systems. FUNCTION OF CHANGED OBSERVATIONS The PWM function allows compatible 4-pin controllers, including those built into multiple main panels, for intelligent speed change and thus fan noise level. With PWM, the system can increase cooling when needed, or work in maximum silent mode when not necessary.
