bequiet! LIGHT WINGS LX 140mm PWM 3-Pack White — 140×25 mm fans, 1200 RPM, 95 m³/h, RGB LEDs

The be quiet! LIGHT WINGS LX 140mm PWM 3-Pack White combines optimized fan blades, a frosted impeller illuminated by 16 hub LEDs and a frame designed to reduce air leaks, delivering balanced airflow and visible ARGB lighting for PC cases. Each fan in the triple pack supports PWM speed control up to 1200 RPM, offers an airflow of 95 m³/h and uses rifle bearing technology for extended service life.

Advantages

The Light Wings LX 140mm PWM White provides a blend of efficient airflow and strong lighting effects thanks to its optimized blades and illuminated impeller. With a frame outlet that minimizes air leakage and a daisy-chain capable ARGB connector, the fans are both effective for cooling and convenient to install in multi-fan setups. Rifle bearing construction increases longevity, while PWM control enables quieter operation at lower speeds.

Suitable for

• Cooling PC cases with emphasis on ARGB illumination
• Systems requiring quiet, low-speed fans (up to 1200 RPM)
• Multi-fan configurations using daisy-chained ARGB connections

How to use

Install each 140 mm fan into the case mounting points using the supplied screws, aligning airflow direction as required for intake or exhaust. Connect the PWM cable to a motherboard fan header or fan controller for speed regulation and connect the ARGB input to an ARGB header or controller; use the output connector to daisy-chain additional Light Wings LX fans. Configure PWM and ARGB settings in your motherboard or controller software as needed.

Recommendations

For optimal results, use these fans in balanced intake/exhaust arrangements and keep ARGB cables routed to avoid interference with airflow. When aiming for minimal noise, set PWM profiles to limit maximum RPM below 1200. Ensure compatible 3-pin/4-pin ARGB headers or a dedicated controller are available for lighting control.
