120mm Lian Li UNI FAN SL-INF Wireless ARGB PWM Reverse Blade, black

Lian Li UNI FAN SL-INF is a 120mm wireless ARGB PWM reverse-blade case fan in black. Designed for PC cases and radiators, the fan combines addressable RGB illumination with PWM speed control to balance cooling performance and acoustic comfort. The reverse-blade geometry is engineered to optimize airflow delivery and reduce turbulence, helping maintain lower component temperatures in gaming rigs and workstations while fitting seamlessly into modular UNI FAN ecosystems.

Advantages

The reverse-blade design improves directional airflow and reduces noisy vortex formation compared with conventional blade profiles. Wireless ARGB control simplifies lighting integration without additional wiring, while PWM compatibility enables automatic fan speed adjustment based on system temperature. The compact 120mm form factor and standard mounting pattern make the fan interchangeable with most case and radiator mounts, and its black finish provides unobtrusive aesthetic integration.

Suitable for

• Case cooling in compact and mid-tower builds
• Installation on 120mm radiator positions for liquid cooling
• Systems requiring addressable RGB lighting with minimal cabling
• Workstations and gaming PCs needing balanced airflow and low noise

Key specifications

• Fan size: 120 mm
• Blade type: reverse-blade geometry for optimized airflow
• Lighting: addressable RGB (ARGB) with wireless control compatibility
• Speed control: PWM-supported speed regulation
• Color / finish: black housing and blades
• Mounting: standard 120mm mounting pattern suitable for cases and radiators

How to use

Install the fan using the standard 120mm mounting holes in your PC case or radiator bracket, observing airflow direction markings if present. Connect the PWM cable to a compatible motherboard or fan controller header to allow automatic speed adjustment based on system temperature. Pair and configure the ARGB lighting using the Lian Li UNI FAN wireless ARGB interface or compatible controller following the manufacturer's pairing procedure to synchronize colors and effects with other ARGB components.

Recommendations

Place the fan to maintain consistent intake and exhaust airflow paths to avoid recirculation. For radiator use, align the reverse-blade orientation with your cooling loop requirements and verify clearance for fans mounted in push or pull configurations. Ensure the PWM source supports the fan's voltage and control range, and keep the wireless ARGB receiver within recommended distance from controllers or hubs to maintain stable lighting communication.
