120 mm PWM ARGB case fan

The be quiet! Light Wings BL133 is a 120 mm case fan designed for desktop builds that need strong airflow with addressable RGB lighting. It suits system builders who want a white colour scheme and quiet operation at moderate speeds.

16 ARGB LEDs and reversed blade design

Sixteen addressable LEDs light the hub and frosted blades for customisable colour effects. The seven reversed blades are shaped for high static pressure, making the fan effective as a side or bottom intake where airflow must push through restrictive grilles or filters.

28.5 dB(A) noise at 1500 RPM

At full speed the fan reaches 1500 RPM and delivers 48.8 to 83.0 CFM while producing 28.5 dB(A). The PWM curve allows a very low minimum RPM for quieter idle, but the maximum airflow and pressure are limited by the 120 x 25 mm frame size.

Questions about this item

How often will the 120mm PWM ARGB fan's bearings need service?

The Light Wings BL133 uses a long-life rifle bearing rated for continuous operation; no user lubrication or replacement interval is required.

What limits the 1500 RPM fan during sustained high-load cooling?

At 1500 RPM the motor reaches its maximum speed, so airflow tops out at 83.0 m³/h and cannot increase further regardless of temperature.

How loud and hot does the 28.5 dB ARGB fan get when running all day?

The fan stays at its specified 28.5 dB(A) at full speed; PWM control lets it drop to a lower RPM for quieter idle periods.
