be quiet! Light Wings 140mm ARGB PWM High Speed Fan Black

Light Wings 140mm PWM high-speed offers striking ARGB illumination combined with efficient airflow for reliable cooling in desktop PC builds. Designed to balance performance and acoustics, this 140mm fan delivers high rotational speeds while maintaining stable operation and eye-catching lighting effects.

Advantages

The fan provides vivid, addressable RGB lighting that enhances system aesthetics from multiple angles without compromising airflow. Its PWM control enables dynamic speed adjustment to match cooling demands and reduce noise during light loads. The design focuses on durability and consistent performance for case ventilation, radiator cooling, or as a system intake/exhaust fan.

Key specifications

• Size: 140 mm
• Control: PWM speed control
• Lighting: Addressable RGB (ARGB)
• Performance: High-speed operation
• Application: Case fan / radiator fan

How to use

Install the Light Wings 140mm PWM high-speed in a compatible 140 mm mounting location inside the PC case, securing it with the supplied screws. Connect the 4-pin PWM power connector to a motherboard fan header for speed control and the ARGB cable to a compatible ARGB header or controller to enable lighting effects. Configure fan curves and lighting profiles via motherboard software or a dedicated ARGB controller to match cooling needs and visual preferences.

Recommendations

For optimized cooling performance and balanced noise levels, use PWM control with a motherboard fan curve and place the fan where it supports airflow direction across heat sources. Ensure ARGB headers or controllers are compatible with addressable RGB standards used by your system.
