The Lian Li UNI FAN TL FLEX 120 Reverse LED Triple Pack is a three fan cooling solution designed to deliver efficient airflow, customisable ARGB lighting and flexible installation for gaming PCs and enthusiast builds. Each 120mm fan features liquid crystal polymer (LCP) fan blades, a fluid dynamic bearing and a precision engineered 0.6mm blade clearance, operating at speeds of up to 2300 RPM to produce airflow of up to 83.4 CFM and static pressure of 2.66 mmH2O, with a maximum noise level of 34 dBA. The reverse-blade design allows the fans to provide intake airflow while presenting the preferred side towards the interior of the case, making them ideal for showcase builds where clean aesthetics and carefully planned airflow are important. Each fan incorporates 26 ARGB LEDs for customisable illumination, with support for compatible 5V 3-pin ARGB motherboard synchronisation and lighting control through L-Connect 3. The modular interlocking design, adjustable frame orientation and included LED FLEX Receiver help simplify connections and cable management across multiple fans. Measuring 120 x 124 x 28mm per fan, this triple pack includes three reverse blade fans, an LED FLEX Receiver, a 5V 3-pin ARGB cable, a 3-to-12V PWM-to-SATA power cable and an L-Wireless Controller for wireless control of compatible devices. With PWM fan-speed control, flexible installation options and coordinated lighting, the UNI FAN TL FLEX 120 Reverse LED Triple Pack is a versatile choice for multi-fan cooling configurations and visually refined PC builds.

Infinite Glow, Unified Design
UNI FAN TL FLEX feature refined lighting with a seamless infinity mirror design. The ARGB light strip extends around the mounting screws for a cleaner, more unified look.
Engineered Without Compromise
Designed for enthusiasts who demand maximum cooling, TL FLEX pairs premium LCP fan blades with an ultra-tight 0.6 mm blade clearance and precision FDB bearings to deliver exceptional airflow, static pressure, and stability—all certified by PPLP Lab A-Class Performance.

Enhanced Bearing Design
A newly engineered oil retention groove (shown in red) around the fan bearing helps keep lubricant precisely where it’s needed, ensuring consistent lubrication for reduced friction, quieter operation, and long-term bearing reliability.
Ensure the Receiver is Firmly Installed
When attaching the FLEX receiver to the TL fan, make sure it is pushed in completely and securely locked into place. An improper contact may cause poor connection and prevent the fan from functioning properly.
Flexible Control, Your Way
Using the included FLEX receivers, the UNI FAN FLEX Series supports both L-Connect 3 and motherboard control, giving you the flexibility to choose the control mode that best fits your setup.

Built for Motherboard Sync
Control fan speed and lighting through the motherboard BIOS or motherboard software without a wireless controller.
(MB Software Controls Lighting & Fan Speed)
Longer redesigned cables make routing cleaner and cable management easier.
