Single 120 mm Reverse-Blade ARGB Fan

This single Lian Li UNI FAN SL-INF Flex 120 mm fan uses a reverse-blade design and multi-zone ARGB lighting for builds that want a clean aesthetic. It is sold without a controller, so buyers who already own a compatible Lian Li hub or plan motherboard-only control can add exactly one unit.

Motherboard PWM and 5 V ARGB Installation

Connect the fan to a standard 4-pin PWM header for speed control and a 5 V 3-pin ARGB header for lighting sync through motherboard software. The package includes no controller, so a separate Lian Li UNI FAN controller or wireless receiver is required if you want to use L-Connect 3 or wireless features.

No Controller Included

Because this SKU ships without any controller, it suits builders expanding an existing UNI FAN chain or wiring directly to motherboard headers. It does not suit first-time buyers who need a starter kit with the necessary hub and cables to power and synchronise the fan.

Questions about this item

How do I verify the ARGB lighting is syncing correctly with my motherboard software after connecting the 5V 3-pin header?

In your motherboard's RGB control utility, select the 5V 3-pin ARGB header the fan is plugged into; the dual-style edge LEDs should respond instantly to colour, effect and brightness changes applied in the software.

What comes in the single pack and what must I purchase separately to run the fan?

The box contains one 120 mm reverse-blade fan with pre-installed ARGB and PWM cables; a UNI FAN controller or L-Wireless receiver is not included and must be bought separately for wireless or daisy-chain operation.

Which UNI FAN Flex variant should I choose if I want the 1.8-inch 400 x 400 60Hz LCD display?

Select the SL-INF LCD FLEX model; the SL-INF Flex described here has multi-zone ARGB lighting but no integrated screen.
