LIAN LI UNI FAN CL Wireless Reverse Blade PWM ARGB Fan, Fluid Dynamic Bearing, 120mm, Black

The LIAN LI UNI FAN CL is a 120mm reverse blade cooling fan engineered for integration into PC cases and liquid cooling radiators. It utilizes Pulse Width Modulation (PWM) technology, allowing the rotational speed to scale dynamically between 250 RPM and 2100 RPM based on thermal load. At maximum operation, the fan moves 72.73 CFM of air while generating a static pressure of 2.52 mmH2O. The integrated Fluid Dynamic Bearing (FDB) design aims to minimize operational friction and contribute to the unit's Mean Time Between Failures (MTBF) rating of 70,000 hours.

The structural design incorporates an interlocking system, enabling multiple fans to connect directly without requiring individual power or signal cables between units. This reverse blade configuration is suited for intake mounting, optimizing visible aesthetics by orienting the frame supports toward the rear. Illumination is provided by two independently addressable ARGB lighting zones. The control infrastructure requires connection via a standard 4-pin PWM header combined with a 9-pin internal USB header for data synchronization and control management.
