140 mm ARGB case fan

The be quiet! Light Wings BL135 is a 140 mm PWM fan with addressable RGB lighting designed for desktop cooling. It fits standard 140 mm mounting points and connects via a 4-pin PWM header for speed control. The white frame and blades suit light-themed builds while the ARGB LEDs can synchronise with compatible motherboard software.

Sustained-load behaviour

At the rated 1300 RPM maximum the fan delivers up to 87.3 cubic metres per hour of airflow while noise stays at 25.5 dB(A). Seven silence-optimised reversed blades are shaped to maintain steady pressure and reduce turbulence during continuous operation. A rifle bearing rated for 60000 hours supports long-term reliability under constant load.

PWM and ARGB limits

The 4-pin PWM connector allows the motherboard to vary speed down to a low minimum RPM for quiet idle states. ARGB control depends entirely on the motherboard header and its software; the fan itself has no independent lighting controller. Builders needing higher static pressure for dense radiators or more airflow than 87.3 m³/h should consider alternative models.

Questions about this item

How loud is the 1300 RPM Light Wings BL135 when it runs all day?

The fan produces a maximum of 25.5 dB(A) at full speed, with a low minimum RPM that keeps noise down during lighter loads.

What motherboard header is required for the 4-pin PWM and ARGB connections?

A standard 4-pin PWM fan header controls speed, while a 5 V 3-pin ARGB header on the motherboard or a compatible controller drives the lighting.

Can the 140 mm BL135 share a PWM curve with older 4-pin fans in the same system?

Yes, the 4-pin PWM interface uses the same signalling standard, so the fan will follow the same curve as other PWM fans connected to the same header.
