be quiet! Light Wings 140mm PWM High-Speed ARGB Fan

The Light Wings 140mm PWM high-speed fan delivers dual-sided ARGB illumination with superior cooling performance. Featuring 20 addressable RGB LEDs on both front and rear, this 140mm fan creates a vibrant lighting display from every angle while maintaining the quiet operation be quiet! is known for.

Dual ARGB Lighting Design

This fan features ARGB lighting on both front and rear surfaces, with 20 individually addressable LEDs providing multiple color and mode options. The subtly lit ring at the back combined with the bright front illumination creates an impressive appearance from any viewing angle. Connect via the 5V 3-pin ARGB connector with daisy chain capability for synchronized lighting across multiple fans.

High-Pressure Performance for Radiators

Engineered with 9 silence-optimized fan blades, the Light Wings delivers 2.3mm H2O air pressure at 2200RPM, making it ideal for both water-cooling radiators and air-cooled heatsinks. The airflow-optimized blade design achieves 71.7 CFM (121.82 m³/h) while maintaining demanding cooling configurations.

Quiet Operation at High Speed

Despite its high-speed capability, this fan operates at just 31dB(A) at maximum 2200RPM. The highly optimized impeller design and 4-pole motor technology deliver powerful cooling without excessive noise. PWM control via the 4-pin connector allows your motherboard or controller to intelligently adjust fan speed based on thermal demands.

Reliable Rifle Bearing Technology

Built with rifle bearing technology, the Light Wings fan offers an exceptional 60,000-hour lifespan at 25°C. The bearing design ensures smooth, long-term operation with minimal friction and wear. Operating voltage ranges from 5-13.2V DC with 0.16A current consumption.

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 9 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.
