140 mm ARGB case fan for quiet builds

The be quiet! Light Wings 140mm PWM is a single 140 mm case fan designed for low-noise cooling and addressable RGB illumination. It suits builders who want subtle lighting on both sides of the fan without sacrificing airflow.

Check motherboard headers and case mounts

Verify that your motherboard provides a 4-pin PWM header for speed control and a standard 5 V 3-pin ARGB header for lighting synchronisation. The fan measures 140 mm square by 25 mm thick, so confirm your case has matching mounting points and enough clearance for the frame.

20 ARGB LEDs and rifle bearing extend options

Twenty addressable LEDs on the front and rear rings enable per-LED colour effects that can be synced through motherboard software. The rifle bearing is rated for 60000 operating hours, and the 4-pole motor keeps noise to 23.3 dBA at 1500 RPM while delivering 50-55 CFM airflow.

Spurningar um þessa vöru

What comes in the box and do I need a separate ARGB controller?

The package contains one 140 mm fan with a 4-pin PWM connector and a 3-pin 5 V ARGB header; no controller is included, so your motherboard must provide an addressable RGB header or you will need a compatible hub.

Should I pick a different RPM or airflow version of this Light Wings fan?

Only the 1500 RPM model delivering 50–55 CFM at 23.3 dB(A) is offered in this 140 mm size, so there is no alternative speed or airflow variant to choose from.

What does the 23.3 dB(A) noise rating mean when the fan is installed in my case?

At the maximum 1500 RPM the fan produces 23.3 dB(A); PWM control lets the motherboard lower the speed for quieter operation under light loads.
