Lian Li UF-SLIN140-1W 14 cm Branco 1600 U/min

The Lian Li UF-SLIN140-1W is a 140 mm Infinity Mirror ARGB case fan in white that combines the UNI FAN SL design with an infinity mirror center and side ARGB strips. It features an aluminium-trimmed mirror ring and a rear ARGB rim around the Lian Li logo, providing layered lighting effects visible from multiple angles. The fan is part of the 2nd-generation UNI FAN SL family with modular interlocking connectors, daisy-chain signal/power pass-through, and an improved cable module for easier radiator compatibility.

Advantages

This 140 mm SL-Infinity fan offers multi-layer ARGB illumination with a centered infinity mirror and side frame lighting, aluminium trims for a 3D indented look, and a rear ARGB rim around the logo. The design improves modularity with removable interlocking keys, a reversible central cable module to reduce radiator clearance issues, and daisy-chain capability to simplify cable routing. Compared to previous SL models, it provides improved airflow and static pressure at lower noise levels and integrates with L-Connect 3 for precise lighting and speed control.

Suitable for

• PC chassis cooling where a 140 mm fan is required
• Systems where ARGB lighting synchronization and visual effects are desired
• Radiator-mounted fans when space or connector orientation is limited
• Multi-fan clusters using daisy-chained UNI FAN SL connectors

How to use

Install the UF-SLIN140-1W in a compatible 140 mm fan mount in your case or on a radiator. Use the interlocking mechanism to connect multiple fans in a cluster and align or remove the keylock if necessary for radiator clearance. Connect the combined 7-pin cable module to the included controller, or daisy-chain fans using the pin-to-pad contact points to pass signal and power through the cluster. Use L-Connect 3 software to configure lighting zones, set fan speed profiles, enable PWM sync with the motherboard, and activate Start/Stop mode for automatic fan stoppage under set temperature thresholds.

Recommendations

For radiator installations, switch the cable module orientation and, if needed, remove the interlocking key to ensure there is sufficient clearance. When using multiple fans, group up to four fans per controller group and use the included Y-type 7-pin splitter to add an additional (fifth) group if required. Configure L-Connect 3 to match fan speed control to your motherboard or to set automatic Start/Stop thresholds for quieter idle operation.
