be quiet! LIGHT WINGS LX PWM, 140mm, Rifle Bearing, ARGB Fan Kit, 3-pack, Black

This fan package contains three 140mm units configured primarily for computer case ventilation. The fans are managed via a 4-pin Pulse Width Modulation (PWM) connection, enabling dynamic speed adjustment across a range extending up to 1200 rotations per minute based on thermal demands. At maximum operational speed, each unit delivers an airflow of 56 CFM (95 m³/h) and generates a static pressure rating of 0.9 mmH₂O. The design prioritizes performance efficiency while limiting acoustic output to a maximum of 22.9 dB.

Each fan utilizes Rifle Bearing technology, a mechanism selected for extended durability and consistent performance, resulting in a rated mean time to failure (MTTF) of 60,000 hours. Illumination is provided by integrated Addressable RGB (ARGB) lighting, featuring 16 LEDs per fan and requiring a separate 5V 3-pin ARGB connection for synchronization and control. The installation kit includes the necessary mounting screws and dedicated ARGB connection cables with a daisy-chaining option.
