Case Fan lian li UNI FAN TL Wireless ARGB PWM 140mm White

The lian li UNI FAN TL Wireless ARGB PWM 140mm in white is a case cooling fan designed for PC systems where adjustable illumination and precise thermal control are required. This 140mm fan integrates wireless ARGB lighting control with PWM-based speed regulation to allow synchronized lighting effects and variable airflow. It is intended for installation in chassis fan mounts or on compatible radiators to improve case ventilation, lower component temperatures and provide customizable lighting without cable clutter.

Advantages

This fan combines ARGB lighting with PWM fan control to deliver both visual customization and efficient cooling. Wireless ARGB control reduces cable routing complexity while the PWM input enables automatic speed adjustment according to motherboard or fan controller signals. The 140mm frame balances airflow and noise performance, and the white finish complements light or contrast-themed builds. Designed for easy mounting, the fan fits standard 140mm locations and supports integration with common system control methods.

Suitable for

• Custom desktop PC builds requiring balanced airflow and lighting integration
• Radiator-mounted cooling loops in air or liquid-cooled systems
• Systems where reduced cable clutter and centralized ARGB control are preferred
• Case upgrades to improve thermal performance and add controllable illumination

Key specifications

• Fan size: 140 mm frame diameter for increased airflow compared with 120 mm models
• Lighting type: Addressable RGB with wireless control for synchronized effects
• Speed control: PWM-compatible motor for variable RPM based on control signal
• Frame color: White finish suitable for light-themed or contrasting builds
• Mounting: Standard 140 mm screw pattern for chassis or radiator installation
• Performance focus: Designed for a balance of airflow and acoustic comfort

How to use

Install the fan into a suitable 140 mm mount in the chassis or onto a compatible radiator using the supplied screws. Connect the fan’s PWM cable to a motherboard fan header or a PWM-capable fan controller to allow automatic speed adjustments based on system temperatures. Use the wireless ARGB receiver or hub provided by the manufacturer to pair and control lighting effects; follow the lian li pairing procedure to synchronize multiple UNI FAN TL units if used. Ensure the airflow orientation matches the intended intake or exhaust direction and verify clearance around the fan for unobstructed airflow.

Recommendations

For optimal thermal and lighting results, position fans to create a coherent airflow path (intake at front/bottom, exhaust at top/rear) and enable PWM control through the motherboard BIOS or a compatible controller. When combining multiple fans, use the manufacturer’s wireless ARGB hub to synchronize effects and avoid interference. Regularly check mounting screws and clean the fan blades to maintain performance and low noise levels.
