Ventoinha de caixa Lian Li UNI FAN SL-INF Wireless ARGB PWM 140 mm, branca

The Lian Li UNI FAN SL-INF is a 140mm wireless ARGB PWM case fan in white designed for PC cooling and customizable illumination. It integrates addressable RGB lighting with PWM speed control to balance airflow and acoustic performance. The fan connects to Lian Li’s UNI Fan ecosystem for synchronized lighting and simplified cable management while providing a compact profile suitable for modern cases.

Advantages

This white 140mm fan offers adjustable PWM control that allows precise regulation of rotational speed for optimized cooling and reduced noise. The addressable RGB LEDs provide individually controllable lighting effects that can be synchronized across compatible devices. Wireless control simplifies installation and reduces cable clutter, and the modular mounting design facilitates stacking or daisy-chaining with other UNI FAN SL-INF units for a uniform appearance.

Suitable for

• Airflow-focused PC builds that need a balance between cooling and acoustics
• Systems requiring synchronized ARGB lighting across multiple fans and components
• Compact or modern PC cases where a slim, white finish complements the interior
• System builders and modders seeking modular fan assemblies for clean cable routing

Key specifications

• Fan size: 140 mm diameter
• Lighting type: Addressable RGB (individually controllable LEDs)
• Speed control: PWM (pulse-width modulation) for variable fan RPM
• Color/finish: White housing and fan blades
• Connection: Wireless lighting control compatible with Lian Li UNI ecosystem and standard PWM fan headers for speed management
• Mounting: Standard 140mm mounting pattern for case installation

How to use

Install the 140mm fan into the case using the standard mounting holes and secure it with screws. Connect the PWM cable to a compatible motherboard or fan controller header to enable automatic speed regulation. Pair or link the fan with other Lian Li UNI components according to the manufacturer’s instructions to enable synchronized ARGB effects and wireless control. Adjust fan curves in the BIOS or with software to set preferred temperature-to-speed behavior.

Recommendations

Position fans to create a clear airflow path—intake at the front or bottom and exhaust at the rear or top—and use PWM control to reduce speed during light-load operation to minimize noise. For consistent lighting, use fans from the same series and follow the UNI ecosystem guidelines for pairing and firmware updates.
