The Lian Li UNI FAN CL FLEX is a 120mm high-performance PC cooling fan designed to combine flexible installation with clean cable management and coordinated lighting for modern gaming and enthusiast builds. uipped with Fluid Dynamic Bearings, the standard-blade CL FLEX fans operate from 250 to 2100 RPM, delivering up to 77.34 CFM airflow and 2.52 mmH2O static pressure at 29.8 dBA. Its interlocking design allows multiple fans to be connected together, reducing cable clutter and simplifying installation, while the flexible frame design provides greater adaptability when mounting fans in different configurations. Integrated ARGB lighting adds customisable illumination across the fan assembly, with compatibility designed for synchronised lighting setups.

Personalised Control Through L-Connect 3
L-Connect 3 brings fan speed, fan curves, and lighting effects into one intuitive interface, allowing users to fine-tune cooling performance and RGB style with presets or custom profiles.
Custom Device Naming
Rename devices, arrange fan order, and manage fan groups in L-Connect 3 to mirror your actual build layout, making setup and future adjustments easier.
Strong Airflow, Controlled Acoustics
With FDB bearing, UNI FAN CL FLEX balances strong airflow, static pressure, and acoustics for reliable cooling.
Aluminium Centre Nameplate
The aluminium-style centre nameplate creates a refined focal point that elevates the clean RGB design.
