140mm Lian Li UNI FAN SL-INF Reverse Blade RGB case fan, model UF-RSLIN140-1B

The 140mm Lian Li UNI FAN SL-INF Reverse Blade RGB case fan (model UF-RSLIN140-1B) is a 140 mm cooling fan designed for PC chassis and radiator mounting. It uses a reversed blade profile intended to influence airflow characteristics and includes addressable RGB lighting that can be synchronized with compatible motherboards or controllers. The fan is offered as a component for improving system ventilation and supporting RGB aesthetics while aiming to deliver quiet operation during typical desktop workloads.

Advantages

The reverse blade profile is engineered to modify airflow and pressure behavior compared with conventional blade shapes, enabling effective air movement in case or radiator configurations. Integrated addressable RGB lighting provides customizable illumination when connected to compatible control hardware. The 140 mm size balances airflow and acoustic performance, making the fan suitable where larger-diameter fans are preferred for lower rotational speed and reduced noise.

Suitable for

• Case cooling to improve chassis ventilation and component temperature management
• Radiator mounting in liquid cooling loops where a 140 mm fan can be used
• RGB lighting setups that require addressable illumination synchronized with system controllers
• Quiet desktop systems that benefit from larger fan diameters for lower RPM operation

Key specifications

• Fan diameter: 140 mm
• Blade profile: reverse blade design
• Lighting: addressable RGB (requires compatible controller or motherboard for synchronization)
• Mounting: standard 140 mm mounting pattern for chassis or radiator installation
• Intended use: chassis airflow and radiator cooling

How to use

Install the fan using the standard 140 mm mounting holes in your case or radiator shroud, aligning the airflow direction with your cooling strategy (intake or exhaust). Connect the fan power and RGB connectors to compatible headers on the motherboard or to a supported RGB controller to enable lighting synchronization. Ensure screws are secured without over-tightening to avoid distortion of the fan frame, and route cables to minimize interference with other components and airflow paths.

Recommendations

Place the 140 mm fan where it complements system airflow: use front or bottom mounting for intake and top or rear mounting for exhaust as appropriate. When used on radiators, consider push, pull, or push-pull configurations depending on your cooling goals and radiator thickness. Verify motherboard or controller compatibility for addressable RGB before purchase to ensure full lighting control.
