Three-fan ARGB bundle

The be quiet! BL124 LIGHT WINGS LX triple pack delivers three 120mm PWM fans designed for cases that prioritise visible lighting. Each unit features an illuminated hub and frosted blades driven by 16 addressable LEDs. A daisy-chain cable simplifies routing for synchronized effects across the set.

Upgrade from basic or single fans

Builders replacing stock case fans or single non-ARGB units gain both coordinated lighting and higher static pressure in one step. The jump is worth it when the build demands visible illumination plus the 2.51 mmH2O pressure needed for restrictive radiators or dense mesh fronts.

Sustained 2100 RPM with rifle bearing

An innovative closed-loop motor holds the 2100 RPM target regardless of airflow resistance, so pressure stays consistent under load. The rifle bearing is rated for 60000 operating hours, while the low start-up speed keeps noise at 30.9 dBA during long sessions.

Questions about this item

Will the 120mm by 25mm frames fit my case mounting points?

Each fan measures 120mm square and 25mm thick, matching standard 120mm case mounts.

How do I connect the 4-pin PWM and ARGB cables without losing control of the 16 LEDs?

Plug the 4-pin PWM header into the motherboard fan header and the ARGB cable into a 5V ARGB header; use the daisy-chain connectors to link all three fans in series.

When should I plan to replace the rifle-bearing fans rated for 60000 hours?

At continuous 2100 RPM operation the bearing is rated for 60000 hours; expect replacement after several years of 24/7 use or if noise rises above the specified 30.9 dBA.
