Controller Lian Li UNI HUB SL-INF L-Connect 3 black (model 12SLIN-CONT3B) for UNI Fan SL series

The Lian Li UNI HUB SL-INF L-Connect 3 controller for the UNI Fan SL series is a compact black hub designed to centralize RGB lighting and fan speed management in custom PC builds. It provides a single connection point for multiple UNI Fan SL units and integrates with L-Connect 3 software to enable synchronized lighting effects and unified fan control. The hub supports signal routing to motherboard headers and to Lian Li’s application, allowing configuration of lighting profiles and fan curves while keeping internal cabling organized.

Advantages

This controller consolidates connections for UNI Fan SL series fans and RGB channels into one compact unit, simplifying cable routing and system assembly. It enables synchronization of lighting effects across connected fans through L-Connect 3 and supports unified fan speed control, which helps maintain consistent airflow and noise management. The small footprint and black finish make it suitable for a range of case interiors where discreet hardware is required.

Suitable for

• Custom desktop PC builds using UNI Fan SL series fans
• Systems requiring synchronized RGB lighting across multiple fans
• Setups where centralized fan and lighting control is preferred for cable management
• Users who want to configure lighting and fan curves via L-Connect 3 or motherboard headers

Key specifications

• Form factor: compact controller hub designed for internal PC installation
• Color: black finish suitable for discreet appearance inside chassis
• Compatibility: intended for use with Lian Li UNI Fan SL series
• Control interface: integration with L-Connect 3 software and motherboard header connectivity for fan/RGB control
• Functionality: centralized RGB signal distribution and fan speed coordination

How to use

Connect the UNI Fan SL units to the hub using the dedicated connectors included with the fans, then link the hub to the motherboard headers or to a system USB internal header as required for L-Connect 3 communication. Install and run L-Connect 3 on the host PC to detect the controller and configure lighting profiles, zones, and fan speed curves. Ensure secure mounting of the hub in an appropriate location inside the chassis to avoid strain on cables and to maintain airflow paths.

Recommendations

Route cables to minimize obstruction of airflow and use the hub’s centralized layout to keep fan and RGB wiring tidy. When using software control, verify that L-Connect 3 is up to date and that firmware for connected devices is current. If connecting to motherboard headers, confirm header types and settings to prevent signal conflicts between software and BIOS-level controls.
