140mm PWM High-Speed ARGB Fan

The be quiet! BL129 LIGHT WINGS LX is a 140mm PWM case fan designed for high-speed airflow. It features addressable RGB lighting for visual customisation. The single fan unit comes in a black finish. It suits builders who need strong cooling performance with lighting control.

Ideal for High-Airflow Builds

This fan suits enthusiasts building systems that demand high static pressure or airflow. The PWM function allows automatic speed adjustment based on temperature. Buyers needing silent low-RPM operation should look elsewhere. Those requiring non-LED fans or smaller form factors must choose a different model.

140mm High-Speed PWM Specification

The defining specification is the 140mm high-speed PWM design. This determines the mounting compatibility and the maximum airflow potential. Verify your case supports 140mm mounting points before purchase. The high-speed rating indicates performance focused on thermal throughput.

Questions about this item

Does the 140mm frame of the BL129 line up with standard 140mm case mounts?

Yes, the 140mm square frame matches the standard mounting pattern used on most mid-tower and full-tower cases.

Which motherboard headers are required for the PWM and ARGB connections on the BL129?

Connect the 4-pin PWM lead to a CPU or chassis fan header and the 3-pin 5V ARGB lead to a 5V addressable RGB header; do not plug ARGB into a 12V RGB header.

How should I clean the BL129 fan blades without damaging the ARGB diffuser?

Use low-pressure canned air or a soft brush; avoid liquids and do not spin the blades with compressed air to protect the bearing.
