140mm UNI FAN SL-INF Reverse Blade ARGB PWM Standalone Fan from Lian Li

Lian Li UNI FAN SL-INF 140mm ARGB PWM Fan Black

Infinity In Motion The Lian Li UNI FAN SL-INF bends light into illusion, projecting endless reflections through its signature side-mounted infinity mirrors—each pulse, pattern, and glow drawing you deeper into a shifting visual loop. With three lighting zones per fan and a mirror design on the side, it’s not just RGB—it’s a moving light sculpture inside your case. Behind the spectacle, its daisy-chain modular design keeps cabling neat and installs intuitive, letting the fans snap together as one cohesive unit. Fully controlled through L-Connect 3, every gradient and speed curve becomes yours to command—built for those who don’t just want to light their build, but lose themselves in it.

Connected Cooling

Reverse Blade Flow Direction

Reverse Blade TechnologyThis fan pushes 71.6 CFM of airflow through reversed blades, making it a powerful choice for maintaining low temperatures in push/pull configurations. Its PWM functionality allows for dynamic fan speed control, adjusting to your system’s needs for good cooling without waste or noise.



Daisy Chain DesignThe interlocking design enables up to four fans to be daisy-chained together with ease, eliminating clutter and simplifying installation. This feature transforms UNI Fans into a game-changer, providing effortless control and unified performance in modern PC builds.

One Set, One Cable

Simple & StraightforwardThe included cable module connects to a dual-output lead: 4-pin PWM for fan speed, and 3-pin 5V ARGB for lighting. These split cables plug straight into your motherboard headers, offering full functionality without a controller. Simple, direct, and ideal for smaller builds or adding just one more fan to your setup.

Your Fans, Your Personality

Triple Zone Fan ARGB Strips with Infinity Mirror Highlighted with Colour Effect

Dual Infinity DesignThe UNI FAN SL-INF features three distinct lighting zones per fan: the fan blades, the outer frame, and the signature infinity mirrors on each side. Together, they create a layered platform for advanced lighting effects across your build. Every zone is fully customisable through L-Connect 3, allowing for dynamic gradients, alternating color schemes, or clean, uniform visuals.

Excellent Modularity

Removable Keylock
Each SL-Infinity fan features an interlocking key to keep your daisy-chained setup securely aligned—but now, that key is fully removable. This small yet important tweak frees up space around tight radiator layouts, making it easier to work around fittings without compromising the clean stackable design.

Reversible Cable
The redesigned cable module now sits dead centre on the fan frame and offers reversible orientation. This flexibility makes it much easier to manage cable routing, especially near radiator inlet and outlet ports—reducing interference, improving fitment, and keeping everything tidy no matter the configuration.

Behind the Scenes

Precision PBT BladesThe thick polybutylene terephthalate (PBT) blades are engineered for rigidity and minimal flex. This design clears lots of room for static pressure while preventing turbulence.

Reinforced Core StabilityMoving inward, a high-strength metal bearing secures the impeller in place. A surrounding rubber ring helps absorb vibrations, keeping noise levels low and holding balance.

Exploded view of Fan Anatomy

Engineered Fan FrameA reinforced 25mm-thick fan frame completes the structure, built for durability and airflow efficiency. Rubber dampening pads at each corner absorb residual vibrations, staying quiet at all times.

Fluid Dynamic BearingAt the heart of the fan lies the fluid dynamic bearing (FDB), designed to keep friction to a minimum and max out on lifespan. Supported by a brass nut, stator, and shaft, this system allows for smooth and stable rotation.

L-Connect 3 Software

ARGB Customisation (Motherboard Sync) in L-Connect 3

Become The ArtistWith quick sync, all Lian Li devices—SL/AL UNI FANs and STRIMER PLUS V1/V2—can match lighting effects in seconds. One click ties your setup together, and another can sync everything to your motherboard’s software. No guesswork, no mismatch—just instant coordination across your entire rig.

Fan Curve Setup in L-Connect 3

Cool When Needed, Silent When NotL-Connect 3 introduces a Start/Stop mode that halts the fans entirely when system temperatures are low—keeping your build whisper-quiet under 50°C. For more precise thermal tuning, sync fan speed directly to your motherboard (PWM), letting your system decide exactly when extra airflow is needed.

Ecosystem Setup in L-Connect 3

Your Unified EcosystemL-Connect 3 hands over full control of your fan lighting. You can independently select effects for the fan blades, the inner frame, or both—offering an endless array of combinations to suit any theme. (1) Choose between custom or preset effects, (2) define exact colours, adjust brightness, speed, and direction. Whether you want symmetry or layered contrast, it’s all at your fingertips.
