Three-Fan ARGB Kit for 140mm Mounts

The be quiet! Light Wings LX BL131 triple pack delivers three 140mm PWM case fans with addressable RGB lighting. Each unit uses a rifle bearing rated for 60000 hours and a closed-loop motor that maintains speed under load. The bundle suits builders who want matching airflow and illumination in a single purchase.

Ideal for Showcase Builds Needing High Air Pressure

Enthusiasts building windowed cases with restrictive radiators or dense mesh will benefit from the 9-blade design that produces 75.3 CFM and 2.45 mmH2O at 1800 RPM. Buyers who need silent operation above all else or who lack a 5V ARGB header on their motherboard should look at something else.

1800 RPM Top Speed Defines the Cooling Envelope

The maximum rotational speed of 1800 RPM sets the peak airflow of 75.3 CFM and the peak noise of 30.5 dBA. PWM control allows lower speeds for quieter idle, but the 1800 RPM ceiling determines whether this kit can move enough air for your thermal target.

Questions about this item

How can I confirm the 1800 RPM speed is reached after installing the BL131 fans?

Connect the 4-pin PWM headers to the motherboard, then monitor RPM in BIOS or fan-control software while the system runs a load; the closed-loop motor maintains the target speed regardless of resistance.

What comes in the triple pack and which cables must be sourced separately?

The box contains three 140 mm fans with rifle bearings, each with an ARGB daisy-chain cable attached; a motherboard ARGB header or a compatible controller is required to power the lighting.

Should I choose the 140 mm high-speed white ARGB version or a different size for maximum air pressure?

This 140 mm model delivers 2.45 mmH₂O static pressure at 1800 RPM; smaller or lower-speed variants in the range produce less pressure, so select this version when pressure matters most.
