120mm UNI FAN SL-INF Reverse Blade ARGB PWM Triple Fan Pack from Lian Li
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.

Reverse Blade TechnologyThis fan pushes 63.6 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
Triple Fan Pack - Direct to UNI HUBIn the multi-fan configuration, each SL-Infinity fan interlocks with the next, physically and electrically. The entire group is powered and controlled via a single proprietary 7-pin connector, routed through the reversible central cable module and plugged directly into the included Lian Li controller. This setup eliminates excess wiring and delivers full PWM and ARGB control through one streamlined link—purpose-built for tidy, scalable installations.

Proprietary 7 PINPlugs into UNI HUB
INCLUDED UNI HUB
The controller starts strong with support for fan clusters via an ARGB + PWM signal, allowing up to four fans per group to be daisy-chained and controlled together. Alongside that, (1) SM TYPE ports extend compatibility to devices like the Galahad AIO pump's ARGB cable. Each SM port delivers up to 5W, with SYNC 4 and SYNC 2 echoing the lighting effects of Ports 4 and 2 respectively—perfect for symmetrical setups.
Power delivery comes from (3) dual SATA cables, with a combined max input of 29W. The main SATA connection is always required, while the secondary one should be used when powering more than 12 fans or running high-output lighting modes like static white. (4) A 9-pin USB cable connects the hub to your motherboard for L-Connect software control, and (5) 5V ARGB + 4-pin PWM cables allow for full sync with your motherboard’s lighting and fan profiles.
Your Fans, Your Personality
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.

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.
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.
