Fan Lian Li Uni Fan SL140

The Lian Li Uni Fan SL140 is a 140 mm case fan engineered for efficient cooling in PC builds. It operates between 500 and 1500 RPM, produces a maximum air pressure of 1.67 mmH2O and uses Fluid Dynamic Bearing (FDB) technology to improve longevity and reduce operational noise. The fan comes in a white finish and features a modular, interlocking design that links with other UNI FAN SL140 units and an included UNI HUB to simplify power and lighting management.

Advantages

The modular interlocking design allows multiple fans to connect via the included cable modules, reducing cable clutter and simplifying installation. The UNI HUB provides four dedicated UNI FAN ports, each able to host a chain of up to four fans, enabling control of up to 16 fans from a single hub. FDB bearings deliver quieter operation and extended service life, while the supported RPM range provides a balance between airflow and noise. Integrated RGB lighting can be configured for color, brightness and effects through L-Connect or passed to compatible motherboard control.

Suitable for

• ATX and micro-ATX desktop PC cases requiring 140 mm fans
• Gaming builds where modular RGB lighting synchronization is desired
• Cooling setups that benefit from multiple fans controlled together

How to use

Install the Uni Fan SL140 into a compatible 140 mm fan mounting location using the supplied screws. Connect fans to each other using the modular interlocking cables and plug the chain into one of the four ports on the included UNI HUB. Use the L-Connect software to adjust fan RPM, lighting color, brightness and effects, or connect the hub to a compatible motherboard header to pass lighting control to the motherboard. Ensure the hub is powered according to the manufacturer instructions and that cables do not obstruct airflow.

Recommendations

Place fans to create a clear airflow path (intake at front/bottom, exhaust at rear/top). When chaining multiple fans, balance airflow and noise by adjusting RPM in software. Keep the UNI HUB in a location with adequate ventilation and avoid routing cables across sharp edges.
