LIAN LI has introduced the UNI FAN SL Flex and UNI FAN CL Flex, expanding its wireless cooling lineup with two new fan series designed for gamers and PC builders. The new models arrive with the Flex Receiver, a compact controller that simplifies installation while providing wireless fan speed and RGB lighting control through L-Connect 3 software.
Available from July 31, 2026, the new fans are offered in single and triple-pack configurations, giving users an easier way to build or upgrade a wireless cooling setup.
The new Flex Receiver serves as the connection point for both power and wireless communication. It receives power through a standard 4-pin PWM header while managing lighting and fan speed through L-Connect 3.
Users can choose between two operating modes depending on how they want to control RGB lighting. In Standard Mode, both lighting and fan speed are managed wirelessly through L-Connect 3. Those who prefer motherboard synchronization can connect the included 5V 3-pin ARGB cable, allowing RGB effects to be controlled by motherboard software while keeping fan speed management through the receiver.
Each receiver supports up to four UNI FAN SL Flex or UNI FAN CL Flex fans. It is also compatible with existing UNI FAN CL Wireless models, making upgrades easier for users already using LIAN LI’s wireless ecosystem.
The UNI FAN SL Flex receives a visual refresh with infinity mirror lighting integrated into both side frames, replacing the aluminum side plates found on previous versions. LIAN LI has also changed the center hub medallion to black while keeping two independent RGB lighting zones powered by 52 LEDs.
Performance specifications include:
- Fan speed up to 2,000 RPM
- Airflow of 66.5 CFM
- Static pressure of 2.5 mmH₂O
- Noise level of 29 dBA
- Available in standard and reverse-airflow models
- Black and white color options
The reverse-airflow version allows users to maintain a cleaner appearance when mounting intake fans at the front or bottom of a PC case.
The UNI FAN CL Flex keeps the same design and cooling performance as the original CL series while adopting the new Flex Receiver for wireless connectivity.
Its specifications include:
- Maximum speed of 2,100 RPM
- Airflow up to 77.34 CFM
- Static pressure of 2.52 mmH₂O
- Noise level of 29.8 dBA
- Standard and reverse-airflow variants
- Black and white versions
With higher airflow than the SL Flex, the CL Flex is aimed at users who prioritize cooling performance while remaining within the LIAN LI wireless ecosystem.
Both fan series are managed through L-Connect 3, allowing users to customize RGB effects, create fan curves, and save multiple performance profiles. Triple-pack versions include the L-Wireless Sync Controller, which supports up to 10 channels and works with several LIAN LI products, including:
- UNI FAN Flex Series
- UNI FAN Wireless Series
- HydroShift II Series
- LANCOOL 217 INF
- LANCOOL V150 INF
- Strimer Wireless
This allows users to manage multiple compatible devices from a single controller through the same software interface.
The LIAN LI UNI FAN SL Flex and UNI FAN CL Flex are available beginning July 31, 2026.
UNI FAN SL Flex
- Single Pack – $21.99

The introduction of the Flex Receiver expands LIAN LI’s wireless cooling lineup while maintaining compatibility with existing wireless products.
