The Lian Li SL-INF is the latest evolution of the innovative UNI fan design, featuring a unique interlocking mechanism which puts the connectors directly on the frame of the fan. Utilising this system, you can daisy chain up to four fans together and connect them to a controller or motherboard with just a single cable. What’s more, you can create two clusters of three fans and daisy chain them together, for a total of six fans powered by just two cables. Furthermore, the SL-INF offers spectacular performance, with a maximum airflow of 72.7CFM and a static pressure of 2.88mmH2O while being whisper quiet at just 28dB(A). These fantastic capabilities are coupled with a stunningly beautiful aesthetic, as the SL-INF features an infinity mirror design for its RGB lighting.

Lian Li has redefined fan connectivity with their innovative UNI fan design. This unique design negates the need for multiple cables to power your case fans. In fact, you can power and control the lighting of four UNI fans with a single cable! The Lian Li SL-INF UNI fan has connectors built into the fan frame, facilitating a streamlined configuration. Additionally, the fans integrate removable keylocks as well as a combined power and RGB cable, making the SL-INF perfect for using with radiators.

Furthermore, you can daisy chain two clusters of three SL-INF fans together with the addition of one more cable, keeping clutter to a minimum. To control all these fans, you can either connect to a 4-pin or 3-pin 5V header on your motherboard or to the Lian Li Fan Controller, that can support up to 16 fans at the same time.

In addition to this, each Lian Li SL-INF fan also delivers outstanding performance, with an astounding airflow of 72.7CFM, at a static pressure of 2.88mmH2O. What’s more, they are whisper quiet with a maximum acoustic noise of just 28dB(A).


The Lian Li UNI SL-INF Fans boast three stunning infinity mirrors as the centrepiece of their RGB lighting. The first of these mirrors can be found on the fan hub, with the layers of lighting spaced just 0.5mm apart. This creates the illusion of a deep well at the centre of the fan. The other two mirrors are located on the sides of the fan frame. With their unique geometric shape, a 3D image is created, that seems to stretch through the frame of the fan.

In addition to the captivating infinity mirrors, the SL-INF integrates several RGB strips within its design. In fact, the fan sports RGB lighting circling the rim of the Lian Li logo, and four LED strips arranged around the fan blades.

Controlling the RGB of UNI fans is made simple, thanks to Lian Li’s L-Connect software. Utilising this powerful program, you can assign different colours and lighting effects to individual fans, clusters, or synchronise them together for a unified aesthetic.
