LIAN LI has launched the UNI FAN SL FLEX and UNI FAN CL FLEX, two 120mm case fans built around a new FLEX Receiver that handles both power delivery and wireless lighting and speed control. The SL FLEX is upgraded with infinity-mirror lighting on both side frames, while the CL FLEX keeps its established look and adds the FLEX Receiver for expanded control. Both fans launched on July 31, 2026, in Taipei, Taiwan.

Flexible Control With the FLEX Receiver
The FLEX Receiver is powered via a 4-pin PWM header and supports up to four SL FLEX or CL FLEX fans per unit. In Standard Mode, the receiver handles wireless lighting and fan speed control through Wireless L-Connect. Connecting the included 5V 3-pin ARGB cable instead shifts lighting control to the motherboard, syncing the fans with the rest of a motherboard-controlled RGB setup. The receiver is also backward compatible with LIAN LI’s existing CL Wireless fans.
UNI FAN SL FLEX: Infinity Mirror on Both Sides
The SL FLEX replaces its aluminum side plates with an infinity-mirror design on both frames and swaps the hub medallion from silver to black, while keeping two separate lighting zones across 52 LEDs total. It spins up to 2,000 RPM for up to 66.5 CFM of airflow and 2.5 mmH2O of static pressure at 29 dBA, with a reverse-airflow version available for clean front- and bottom-intake mounting.
UNI FAN CL FLEX: Proven Design, New Control
The CL FLEX retains its original look and performance while adopting the FLEX Receiver for expanded control options. It runs up to 2,100 RPM for up to 77.34 CFM of airflow at 2.52 mmH2O of static pressure and 29.8 dBA, making it the value airflow pick of the FLEX family. Like the SL FLEX, it ships in standard- and reverse-airflow models in black and white.
L-Connect 3 and the L-Wireless Sync Controller
Lighting and fan curve management for the FLEX series runs through L-Connect 3, with built-in presets and full custom profiles. Triple packs include the L-Wireless Sync Controller, the central hub for L-Wireless Sync-enabled products including the UNI FAN FLEX and UNI FAN Wireless series, the HYDROSHIFT II series, the LANCOOL 217 INF and V150 INF cases, and Strimer Wireless, with each controller supporting up to 10 channels.
