Three-pack 120 mm ARGB fans

This Lian Li three-pack delivers three 120 mm case fans with fluid-dynamic bearings and 25 mm thickness. Each fan uses a 3- or 4-pin power connector and includes addressable RGB lighting. The bundle also supplies an L-Connect 3.0 controller for unified management.

Infinity mirror and aluminium trim

A centred infinity mirror with layers spaced 0.5 mm apart creates depth visible from any angle, while thin LED strips run along both side frames. Aluminium trim surrounds the mirror on each side in a top-and-bottom pattern that adds a 3D indented look, and a rear ARGB rim circles the Lian Li logo for extra accent lighting.

Daisy-chain modularity and software control

The daisy-chain design lets the three fans link together with fewer cables, simplifying routing inside the chassis. Lighting effects and fan curves are configured through the included L-Connect 3.0 software, so all three units stay synchronised without separate headers.

Questions about this item

How many 4-pin headers does the L-Connect 3.0 controller need to power all three fans?

The controller draws power from a single 4-pin header and distributes it to the three fans through their built-in daisy-chain connectors.

What case clearance is required for the 25mm thick fans and their aluminium trim?

Each fan measures 25mm thick; the aluminium trim sits flush with the frame, so standard 120mm mounting holes with 25mm depth clearance are sufficient.

Which cable is connected first when installing the daisy-chain — the PWM lead or the ARGB lead?

Connect the PWM cable to the controller port first, then attach the ARGB cable; reversing the order can leave the lighting unresponsive in L-Connect 3.0.
