Lian Li TL Flex 120 Uni Fan ARGB Reverse PWM 120mm Black

The Lian Li UNI FAN TL FLEX 120 Reverse LED is a 120mm case fan designed to deliver efficient cooling, customisable ARGB illumination and flexible installation for gaming PCs and enthusiast builds. This reverse blade model features liquid crystal polymer (LCP) fan blades, a fluid dynamic bearing and a precision engineered 0.6mm blade clearance, providing airflow of up to 83.4 CFM and static pressure of 2.66 mmH2O at speeds of up to 2300 RPM, with a maximum noise level of 34 dBA. Its reverse blade configuration allows the fan to provide intake airflow while presenting the more visually appealing side towards the interior of the case, making it ideal for showcase builds where appearance and airflow direction are equally important. The integrated 26-LED ARGB lighting system creates distinctive illumination, with support for compatible 5V 3-pin ARGB motherboard synchronisation and custom lighting through L-Connect 3 software. The modular interlocking design and included LED FLEX Receiver simplify connections and cable management, while the adjustable frame orientation provides greater flexibility when positioning the fan within different case layouts. Measuring 120 x 124 x 28mm, this single fan pack includes one LED FLEX Receiver and one 5V 3-pin ARGB cable. Combining flexible installation, configurable lighting and reliable cooling performance, the UNI FAN TL FLEX 120 Reverse LED is an ideal choice for clean, visually striking 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.
