What It Is

The Lian Li UNI FAN TL Flex 120mm Normal Blade 3 Pack Black is a set of three 120 mm case fans designed for standard airflow direction in PC builds. It suits builders who want coordinated ARGB lighting and wireless or motherboard-based speed control. The bundle includes a controller and uses LCP blades with a 0.6 mm blade-to-frame gap for 90.1 CFM airflow and 3.97 mmH2O static pressure.

Installation Notes

Mount the fans using standard 120 mm screw holes and connect the included controller for power and signal distribution. The critical step is fully inserting and locking the FLEX receiver; improper contact causes connection issues. Download the latest L-Connect 3 software from the official Lian Li website for full compatibility with PWM, wireless, and 5V 3-pin ARGB motherboard sync modes.

Deciding Specification

These are normal blade fans, not reverse blade variants, so airflow moves in the conventional front-to-rear direction. Buyers needing reverse airflow for specific radiator mounting or push-pull configurations cannot use this pack. Verify your case layout requires standard orientation before ordering.

Questions about this item

How do I verify the fans are running at the rated 2600 RPM after installation?

Monitor fan speed in L-Connect 3 or your motherboard BIOS; the FDB bearings and copper shielding are rated for stable operation up to 2600 RPM.

What comes in the 3-pack box and what must I buy separately?

Three 120 mm normal-blade fans, one controller, and the FLEX receiver are included; no additional cables or mounting hardware are required.

Why choose the normal-blade 12TL1F3B instead of a reverse-blade version?

Normal blades push air toward the motor side for standard intake or exhaust; reverse blades pull air the opposite way, so pick the version that matches your case airflow plan.
