140 mm ARGB case fan with infinity mirror

The Lian Li UNI FAN SL-INFINITY is a single 140 mm fan built for builders who want strong airflow and a distinctive lighting centrepiece. It uses fluid dynamic bearings to reach 1600 rpm while delivering 72.7 CFM at 28 dBA. The centred infinity mirror and side-frame ARGB strips create multi-layer 3D effects visible from any angle.

Daisy-chain modular pin-to-pad connection

Fans link together through Lian Li’s modular pin-to-pad design so only one cable run reaches the motherboard. A separate UNI FAN controller is required because none is included in the box. The 0.5 mm spaced mirror layers and aluminium trim are purely visual; they do not change the electrical interface or the 5 V ARGB signal the header expects.

Check for 5 V ARGB header and controller slot

Verify that your motherboard provides a standard 5 V 3-pin ARGB header or plan to buy a compatible UNI FAN controller. The 140 mm by 25 mm frame must fit your case or radiator mounting points. Builders who need a controller in the box or a different fan diameter should look elsewhere.

Questions about this item

Is the 140 mm size the right choice for my case or should I consider a different fan diameter?

This model is built as a single 140 mm fan with a 25 mm frame thickness, so it fits standard 140 mm mounting points. Check your case or radiator specifications to confirm 140 mm support before ordering.

What does 1600 rpm actually deliver in a real build?

At 1600 rpm the fan moves 72.7 CFM of air while keeping noise at 28 dBA, giving strong airflow for CPU coolers or case ventilation without becoming intrusive.

How does the ARGB connection work and what does it limit?

The fan uses Lian Li's modular pin-to-pad daisy-chain system and requires an L-Connect 3 compatible controller (sold separately) to power and synchronise the infinity mirror and side-frame ARGB lighting.
