Illuminated 120mm PWM case fan

The be quiet! LIGHT WINGS LX BL123 is a 120mm case fan built for systems where visible ARGB lighting is a priority. Its illuminated hub and frosted blades distribute light from 16 addressable LEDs across the rotor. A 4-pin PWM connector allows motherboard speed control from low idle to the 2100 RPM maximum. The rifle bearing is rated for 60000 operating hours.

Builders who want strong airflow with vivid lighting

This fan suits enthusiasts assembling showcase builds that rely on coordinated ARGB effects through the daisy-chain cable. It delivers 61.8 CFM airflow and 2.51 mmH2O static pressure for radiators or restrictive mesh panels. Buyers needing near-silent operation below 30.9 dBA or a thicker 25mm profile for tight clearances should consider other models.

Sustained high-speed cooling behaviour

The closed-loop motor maintains the target 2100 RPM under increasing back-pressure, so airflow stays consistent during extended gaming or rendering sessions. Nine optimised blades preserve the 2.51 mmH2O pressure curve without stalling. Noise rises to the rated 30.9 dBA at full load but remains steady because the rifle bearing avoids speed drift over time.

Questions about this item

Does my motherboard need a 4-pin PWM header to control this fan?

Yes, the fan uses a 4-pin PWM power connector for speed control and requires a compatible motherboard header or fan controller.

Can I daisy-chain multiple BL123 fans on one ARGB header?

The included ARGB cable supports daisy-chaining, so several fans can share a single 5 V 3-pin motherboard header or controller.

How do I verify the fan is running at its rated 2100 RPM after installation?

Monitor the RPM reading in BIOS or fan-control software; it should report close to 2100 RPM under full PWM duty cycle.
