Ventola Lian Li UNI FAN TL Wireless 140mm ARGB PWM Reverse Blade

The Lian Li UNI FAN TL Wireless 140mm ARGB PWM Reverse Blade is a system cooling fan designed for PC cases and radiators. It combines a 140mm form factor with addressable RGB lighting, PWM speed control and a reverse blade profile to balance airflow and audible performance. Wireless lighting control removes the need for complex RGB wiring while PWM compatibility allows motherboard or controller-managed fan speed adjustment.

Advantages

This 140mm fan integrates ARGB illumination with a reverse blade geometry to improve airflow direction and reduce turbulence compared with conventional blade shapes. PWM support enables precise speed regulation for efficient thermal management, and wireless lighting control simplifies setup and cabling inside the chassis. The fan is compatible with common mounting points for case and radiator installation.

Suitable for

• Case cooling in mid-tower and full-tower desktop PCs
• Radiator cooling in water-cooling loops requiring 140mm fans
• Builds that require customizable ARGB lighting without extensive RGB cabling
• Systems where PWM-based automatic fan speed control is preferred

Key specifications

• Fan size: 140 mm
• Lighting type: Addressable RGB (ARGB)
• Control methods: PWM for speed, wireless for ARGB control
• Blade design: Reverse blade profile to influence airflow and noise characteristics
• Mount compatibility: Standard 140 mm mounting pattern for cases and radiators

How to use

Mount the fan using the standard 140 mm screw holes to a case fan location or radiator bracket. Connect the PWM cable to a motherboard fan header or compatible controller to allow speed curves and automatic thermal response. Set up the wireless ARGB receiver according to the included instructions to control lighting; pairing typically involves a USB or dedicated hub connection if required by the hub. Adjust PWM settings in BIOS or software for the desired balance of cooling and noise, and manage ARGB effects through the wireless interface.

Recommendations

Install fans with consistent airflow direction when creating intake and exhaust configurations, and keep cable routing neat to maintain unobstructed airflow. Use motherboard or fan-controller profiles that ramp fan speed based on CPU or GPU temperatures to optimize cooling efficiency while minimizing noise. Verify wireless ARGB signal range and hub placement to ensure reliable lighting control.
