Single 120 mm ARGB case fan

This Lian Li UNI FAN SL Flex is a single 120 mm case fan with normal blade orientation and ARGB lighting. It ships without a controller and is intended for builders who want to add one fan to an existing daisy-chain setup. The black finish matches stealth-themed builds.

5 V 3-pin ARGB and PWM limits

Lighting is managed through a 5 V 3-pin ARGB header on the motherboard while speed is regulated via PWM. Wireless control through L-Connect 3 is also supported when the separate FLEX receiver is present. Without that receiver the fan relies entirely on motherboard headers for both functions.

Check blade direction and header count

Verify that your case layout needs a normal blade fan and not a reverse blade variant before ordering. Confirm the motherboard has a spare 5 V 3-pin ARGB header and a PWM fan header for the connection. Ensure any existing UNI FAN daisy chain has room for one more unit.

Questions about this item

Should I pick the Normal Blade or the Reverse Blade version for my case?

Choose the Normal Blade when you need airflow to push from the front of the fan toward the rear, which is the standard intake direction for most case layouts.

What does the 120 mm size mean for airflow inside my build?

A 120 mm frame fits the vast majority of case mounts and radiators, delivering a balanced mix of static pressure and volume for typical CPU coolers or front-panel intake.

How does the 5V 3‑pin ARGB header limit my lighting control?

The 5V 3‑pin ARGB connection lets motherboard software address each LED individually, but it cannot carry a 12 V RGB signal, so you must use a compatible 5 V header or the optional wireless receiver.
