be quiet! for a long time now didn't included RGB at their well-known and very powerful 120/140mm fans. That recently changed and now be quiet! launches its new Light Wings series fans with ARGB illumination. Besides its characteristic lighting properties, development focused on performance, low-noise operation as well as the manufacturer’s typical high-quality standards. Light Wings fans are equipped with a PWM connector and have one LED ring at the fan’s inlet and another narrow LED ring at the outlet. They are available in 120mm and 140mm sizes.

Vibrant cooling

• ARGB LEDs at the front and rear make for amazing effects
• Individual illumination options thanks to having up to 20 LEDs
• The fan hub can sync up to six ARGB components for an even more impressive appearance

Light Wing’s light rings are equipped with up to 20 individually addressable LEDs with a diffuser to spread the light in both directions. This results in a remarkably uniform illumination and impressive lighting effects. Light Wing triple packs additionally contain an ARGB hub to enable the synchronization of up to six ARGB components in total. The fans can also be connected to motherboards with 5V ARGB-headers and controlled by motherboard software. Light Wings fans allow daisy-chaining of its signal cables for a cleaner case interior.

Silence and Performance

• The nine fan blades of the high-speed version produce the high pressure needed for radiators and heatsinks
• The seven blades of the case fan version provide higher airflow
• Silence-optimized fan blades for low noise-generating turbulences

Light Wings fans are available in two different versions. The PWM model, equipped with seven fan blades and a rotational speed up to 1.700 rpm (120mm) or 1.500 rpm (140mm) is ideally suited as a case fan thanks to its low operating noise level. The PWM high-speed model with nine fan blades and up to 2.500 rpm (120mm) or 2.200 rpm (140mm) is optimized for use on radiators or heat sinks. The thick frame and the adapted impeller result in shorter fan blades with optimized angles for a balance between volume and performance for both models. The high-quality robust rifle bearing guarantees a long-lasting and trouble-free operation with a long service life of up to 60,000 operating hours. All Light Wings fans have a PWM connector that can intelligently control the rotation speed directly via the motherboard.

Advanced PWM function

• Pulse width modulation (PWM) allows compatible 4-pin controllers (including those built into many motherboards) to intelligently vary the speed of the fan
• With PWM your system can ramp up the cooling when it’s needed, or operate in maximum quiet mode when it’s not

Product conception, design and quality control in Germany

• Expressly recommended for use in show cases and gaming systems for best performance and appearance
• High-grade rifle bearing technology contributes to a very long lifespan of up to 60,000 hours
• 3-year manufacturer’s warranty
