Single Wireless Fan for Cable-Free Builds

The Lian Li UNI Fan TL Wireless 140 Reverse Blade is a 140mm case fan that uses 2.4 GHz wireless control for both ARGB lighting and fan speed. It is designed for builders who want to eliminate the usual tangle of RGB and PWM cables inside the chassis. The controller required for operation is sold separately, so existing UNI FAN TL wireless controller owners can expand their setup with a single unit.

Dual-Zone ARGB and Interlocking Frame

Each fan features dual-zone addressable RGB lighting managed through L-Connect 3 software, allowing independent effects on the inner and outer rings. The interlocking frame lets multiple fans snap together, sharing a single wireless signal and reducing the number of individual connections needed. Power is still delivered through a standard SATA connector to the fan itself, while the wireless link handles all control data.

Wireless Control Limits and Controller Dependency

The 2.4 GHz link handles lighting and speed commands without cables, but the fan cannot function without a compatible UNI FAN TL wireless controller purchased separately. Builders without an existing controller must add one to their order, and the wireless bandwidth is shared across all paired devices. Users who prefer a fully wired PWM and ARGB connection, or who need guaranteed operation in environments with heavy 2.4 GHz congestion, should consider alternative solutions.

Questions about this item

Will the 140mm reverse-blade fan fit in the same mounting holes as my current 140mm fans?

Yes, it uses the standard 140mm mounting pattern so it aligns with existing screw holes in your case.

How can I confirm the 2.4 GHz wireless link is active once the fan is installed?

Open L-Connect 3; the software will show the fan's RPM and both RGB zones responding to commands in real time.

Does the single pack include the wireless controller and a SATA power cable, or must I buy them separately?

The pack contains only the fan; the wireless controller and a SATA or external PSU power source are required and sold separately.
