be quiet! Light Wings LX PWM ARGB Fan Kit, 140mm, Rifle Bearing, 3-pack, White

This 140mm pulse-width modulation (PWM) cooling fan is designed for high-performance applications, including case ventilation and effective heat dissipation across radiators or heatsinks. The unit operates at a maximum rotational speed of 1800 RPM, optimized for efficient temperature control under significant computing loads. Its nine-blade structure facilitates a strong airflow rate, reaching 75.3 CFM, while generating 2.45 mmH2O of static pressure. This performance profile ensures consistent air movement required for both dense liquid cooling setups and standard chassis airflow demands.

Operational stability is maintained through the use of a Rifle Bearing mechanism, which contributes to a rated operational lifespan of 60,000 hours. Acoustic output peaks at 30.5 dB when running at full speed. This product includes integrated Addressable RGB (ARGB) illumination, with 16 LEDs per fan, compatible with standard 5V ARGB synchronization ecosystems. This configuration is supplied as a triple pack, complete with necessary mounting screws and daisy-chain ARGB cables for simplified connection across multiple units.
