Case Fan LIAN-LI Cooler 140mm SL-INF (UF-SLIN140-1B) UNI Color:black

ARGB fan with an infinity mirror

Introducing a fresh design language for PC fans along with an especially simple installation,

and advanced customization options for lighting effects to upgrade any system and modern gaming setup.

Fan with an infinity mirror

A blend of the UNI FAN SL and AL series with a unique touch of an "infinity mirror,"

gives the SL-Infinity a clean glow and multi-layered effects clearly visible from any angle.

Center ARGB infinity mirror

A circular infinity mirror element is placed at the center of the fan,

and is calibrated to create multiple layers at 0.5 mm intervals for a precise sense of depth.

Side frame ARGB lighting

Continuing the familiar angular lighting language of the SL series,

the SL-Infinity model adds two thin LED strips on both sides of the blades for a refined look.

Aluminum-framed infinity mirror

Peripheral aluminum strips are placed on both sides of the frame for stability and a premium finish.

The geometric shape of the infinity mirror follows the front ARGB strip

in an upper and lower pattern to create a recessed, three-dimensional appearance.

Unprecedented modularity

The second generation of UNI FAN SL continues the modular interlocking mechanism that connects up to 4 fans in a group,

simplifying cable management while improving compatibility with radiator connections in custom cooling systems.

Daisy-chaining fans (Daisy Chain)

Pin-to-pad contact carries power and control signals across the entire fan cluster,

so there is no need to run a separate cable to each unit.

Removable locking mechanism

The interlocking key between the fans can be removed to improve compatibility and clearance

near the radiator inlets/outlets and tubing fittings.

Reversible cable module

The cable module has been moved to the center of the fan and can be flipped as needed,

reducing clearance issues near the radiator inlet and outlet.

Performance upgrades

The SL-Infinity 120 offers about a 10% performance improvement compared to the SL120, with higher airflow (61.3 CFM),

improved static pressure (2.66 mmH2O), a wide speed range (0, 200–2100 RPM), and a lower noise level (29 dB(A)).

Advanced control with L-Connect 3

The L-Connect 3 interface provides precise control and preview of the lighting effects on SL-Infinity fans,

including profile management, speeds, and full ARGB synchronization tailored to your needs.
