Light Wings 140mm PWM high-speed 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 Nine silence-optimized fan blades for high pressure and low noise-generating turbulences Remarkable performance-to-noise ratio with 31dB(A) at 2,200rpm Long life rifle-bearing gives an operating lifetime of 60,000 hours Three-year manufacturer’s warranty Impressive Lighting Lots of illumination possibilities Light Wings 140mm 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 individualize your PC build. For Radiators and Heatsinks Fan blades optimized for high pressure With a remarkably high air pressure of up to 2.3mm/H2O, Light Wings 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The nine airflow-optimized fan blades provide enough air pressure to make this fan perfect, even in demanding configurations. Quiet Operation Acclaimed be quiet! low noise level A highly optimized 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 and very powerful operation. All features combine to make Light Wings 140mm PWM high-speed 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.
