be quiet! BL121 LIGHT WINGS LX 120mm PWM ARGB Case Fan Triple Pack

Triple pack of 120mm ARGB case fans

The be quiet! BL121 LIGHT WINGS LX triple pack delivers three 120mm PWM fans with addressable RGB lighting for system builders who value coordinated illumination and airflow. Each fan features 16 LEDs shining through frosted blades and an illuminated hub to create a uniform visual effect across the case interior. The rifle bearing is rated for 60000 hours of operation.

Check 4-pin PWM headers

Verify that your motherboard or fan hub provides enough 4-pin PWM headers for three fans or plan for a splitter cable to manage power and speed control. The ARGB connection uses a daisy-chain cable so a single 5V 3-pin ARGB header can drive the lighting for all three units. Ensure your case has mounting points for 120mm fans with 25mm thickness before ordering.

Sustained airflow at 1600 RPM with 25.5 dBA noise

At full speed the fans move 51.5 CFM while generating 1.34 mmH2O of static pressure, maintaining consistent cooling performance during extended workloads. The low starting RPM allows quiet operation at reduced loads without stalling, and the rifle bearing maintains stable acoustics over long sessions. This balance suits radiators or restrictive meshes where steady pressure matters more than peak burst speed.
