Stylish Lighting

RGB lighting has been a cornerstone of the Lian Li UNI FAN Series since they were first introduced, and the Lian Li UNI FAN SL-INF FLEX 120mm Fan is no exception. As an SL design, these fans feature three independent lighting zones, which consist of the fan blades, light strips plus the infinity mirror’s outer edge, and the centre section of the infinity mirror. Each zone can be configured with different colours, creating a captivating display.


Control Multiple Fans L-Connect 3

Controlling multiple UNI FAN SL-INF 140mm Fans is simple, thanks to the daisy chain design and compatibility with L-Connect 3 software. These fans feature pogo pin connectors integrated into the frame. As such, power and control signals can be transmitted from one fan to another when clipped together, without the need for any extra cables. Perfect for keeping clutter to a minimum.

All the fans in a cluster can be managed using Lian Li L-Connect 3 software. This app enables you to create custom fan curves for PWM control and adjust any lighting effects. Furthermore, should your fan cluster include an LCD FLEX fan, you can personalise what is shown on the 1.8" screen using L-Connect 3.
