Lian Li UF-SLIN140-1B

The Lian Li UF-SLIN140-1B is a 140 mm Infinity Mirror ARGB case fan combining the modular UNI FAN SL design with a multi-layered centered infinity mirror and side-frame ARGB strips. It features aluminum trims around the mirror, an ARGB rim behind the rear logo, and improved modularity for daisy-chaining up to four fans per cluster. The reversible central cable module and removable interlocking key simplify installation and compatibility with radiator fittings. Performance is tuned for balanced airflow and static pressure while keeping noise low, and lighting and fan behaviour are controllable via L-Connect 3.

Advantages

The UF-SLIN140-1B offers a layered infinity-mirror lighting center and dual side LED strips for distinct multi-angle illumination. Its 2nd-generation interlocking system supports tool-free connection of multiple fans and a pin-to-pad daisy-chain for signal and power sharing, reducing cable clutter. The central reversible cable module and removable key improve clearance with radiators. Performance improvements deliver higher airflow and static pressure at a wider RPM range with lower noise. Full ARGB control and synchronization are available through L-Connect 3, including intelligent start/stop and motherboard sync options.

Suitable for

• PC builds requiring a 140 mm ARGB fan with decorative infinity-mirror lighting
• Systems with radiators where cable clearance and modular connections matter
• Users who want software control over lighting and fan curves (L-Connect 3)
• Multi-fan setups that benefit from daisy-chaining and controller support

Key specifications

• Fan diameter: 140 mm
• Speed range: 0.2 – 1600 RPM (specified for UF-SLIN140-1B)
• Maximum static pressure: 2.88 mmH2O (manufacturer spec)
• Colour: Black
• Connector: 7-pin cable module to controller (combined power + lighting)
• Compatibility: Daisy-chain up to 4 fans per group; controller supports up to 16 fans (with included controller in triple pack)

How to use

Install the UF-SLIN140-1B in a standard 140 mm mounting position inside the case using the provided screws. If using multiple UNI FAN SL-Infinity fans, align and interlock the fans to form a cluster, remove the interlocking key when required for radiator clearance, and connect the daisy-chain pads to pass signal and power through the cluster. Attach the 7-pin cable module to the included controller and connect the controller to your system according to the manual. Configure fan speeds and lighting effects with L-Connect 3 or sync to motherboard software if preferred.

Recommendations

For optimal cooling and noise balance, use L-Connect 3 to set temperature-based fan curves and enable the Start/Stop feature to stop fans at low CPU/GPU temperatures. When mounting near radiators, orient the reversible cable module to reduce inlet/outlet interference and remove the keylock if necessary to improve fitment. When using a triple pack, the included Y-type 7-pin splitter enables adding a fifth group to the same controller if additional fans are required.
