Lian Li Introduces the Uni Fan SL Flex and CL Flex Fans

LIAN LI Industrial Co., Ltd., A leading manufacturer of chassis and PC accessories, introduces the Uni Fan SL Flex and Uni Fan CL Flex, the easiest entry into Lian Li’s wireless ecosystem. Both fans connect to the new Flex Receiver, a compact controller that handles power delivery via PWM and data transfer via the L-Connect 3 wireless control. The SL Flex features infinity-mirror lighting on both side frames, while the CL Flex now includes the Flex Receiver.

The Flex Receiver is powered via a 4-pin PWM header. In Standard Mode, the receiver supports wireless lighting and fan speed control via Wireless L-Connect. The 5 V 3-pin ARGB cable shifts lighting control to the motherboard software, allowing users to sync the fans with the rest of their motherboard-controlled system. Each receiver supports up to four SL Flex or CL Flex fans, and backward compatibility with existing CL Wireless fans makes the Flex series easier to integrate across builds.

Uni Fan SL Flex: Infinity Mirror on Both Sides
The Uni Fan SL Flex is upgraded with an infinity-mirror side frame design on both sides, replacing the aluminium plates, and swaps the silver hub medallion for black, while keeping two separate lighting zones with 52 LEDs in total. The SL Flex operates at up to 2000 RPM, and delivers up to 66.5 CFM of airflow, 2.5 mmH2O of static pressure and 29 dBA, with a reverse-airflow version available for clean front- and bottom-intake mounting.

Uni Fan CL Flex: Proven Design, New Control

The Uni Fan CL Flex retains its original look and performance while adopting the Flex Receiver for expanded control. The CL Flex operates at up to 2100 RPM, and delivers up to 77.34 CFM 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 is handled 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, HydroShift II series, the LANCOOL 217 INF and V150 INF cases, and Strimer Wireless, with each controller supporting up to 10 channels.

Availability

The Uni Fan SL Flex and CL Flex are available on July 31, 2026.
