Lian Li UNI FAN SL-Infinity 140mm ARGB

The Lian Li UNI FAN SL-Infinity 140 is a single white 140mm PWM case fan with addressable RGB lighting. It combines the original UNI FAN SL and AL designs with a new infinity mirror centrepiece. No controller is included in the package.

Builders who want daisy-chained lighting

The fan uses Lian Li's modular connector system so multiple units link together for synchronised ARGB effects. Buyers who need a standalone fan with a bundled controller or a different colour scheme should look at other models.

Infinity mirror centrepiece with 0.5mm layer spacing

A circular infinity mirror sits at the hub with multiple reflective layers spaced 0.5mm apart, creating a deep 3D glow visible from any angle. Side-frame LED strips and a rear logo rim complete the lighting signature.

Questions about this item

How much noise and heat does the 140mm SL-Infinity fan produce when running all day?

The SL-Infinity 140 model delivers a 10% performance optimisation over its predecessor, giving improved airflow and higher static pressure across a wider speed range at lower noise levels.

What else must I already own to run this fan, given that no controller is included?

You need a motherboard with a standard 4-pin PWM header and a 5V 3-pin ARGB header, or a separate UNI FAN controller hub, to power the fan and control its infinity mirror and side-frame lighting.

Will the 140mm white SL-Infinity fan work alongside my older 120mm UNI FAN SL or AL units in the same loop?

The 140mm SL-Infinity shares the same daisy-chain interlock and ARGB pin-out as earlier SL and AL fans, so it can be linked in series with 120mm models using the same controller hub and cable set.
