Infinity mirror ARGB fan

The Lian Li UNI FAN SL-INFINITY 140 mm case fan combines a centred infinity mirror with side-frame ARGB strips and an aluminium-trimmed rim around the rear logo. Fluid dynamic bearings spin at up to 1600 rpm to deliver 72.7 CFM airflow while keeping noise at 28 dBA. Removable keylocks let the single black fan mount directly to radiators for CPU cooling.

Daisy-chain limits

The fan uses a modular pin-to-pad connector that allows multiple units to be linked in a chain, reducing cable clutter and enabling synchronised lighting through L-Connect 3 software. No controller is included in the box, so a separate UNI FAN controller or a compatible motherboard header is required to power and address the daisy-chained array.

No controller included

Because the package contains only the fan itself, builders who do not already own a Lian Li UNI FAN controller or a motherboard with a 5 V ARGB header cannot control the lighting or fan curves out of the box. Buyers planning a first UNI FAN installation must budget for a controller separately.

Questions about this item

Should I buy the single 140 mm fan or a multi-pack for my build?

The listing is for one 140 mm fan without a controller, so you can add exactly the quantity your case or radiator needs.

What does the 72.7 CFM airflow figure mean when the fan is inside my case?

At 1600 rpm the fan moves 72.7 CFM of air, delivering strong cooling through radiators or mesh panels while keeping noise low.

Does the ARGB lighting work with a standard 5 V 3-pin motherboard header?

Yes, the fan uses a standard 5 V 3-pin ARGB connection and is controlled through L-Connect 3 software for full customisation.
