Each Lian Li UNI FAN SL-INF 120 is equipped with 40 ARGB LEDs. Maximizing brightness, these LEDs have been combined with an infinity mirror to create an incredible lighting effect. The infinity mirror is multi-layered, with 0.5 mm gaps and can be perceived from any angle. The three-dimensional effect and the geometric shape of the frame result in a bold aesthetic that fits any gaming computer. Additionally, the aluminum outline further reflects the effect, meaning that the lighting is visible on both edges and the sides of the frame.

Previously, Lian Li ARGB PWM fans used separate cables for lighting and power. Innovating in design, the Lian Li UNI FAN SL-INF 120 uses a single 7-pin cable that provides both power and lighting. This connects to the new UNI HUB, which is available with the triple packs of SL-INF 120. Alternatively, the single-pack models include a split cable with a 4-pin PWM head and a 3-pin ARGB, which can be connected directly to the motherboard. 

Additionally, the daisy-chaining function has been improved. The connection key, which is placed in the frame of a second fan, can be easily removed. Simply twist it 90° and pull it out of the frame. This increases the compatibility of the SL-INF 120s with radiators, and it also leaves no protruding parts for a cleaner aesthetic.

The UNI HUB controller, included in the Triple Packs, has been optimized for cohesive support. This hub now features two 3-pin ARGB SM ports, specifically designed to support other Lian Li ARGB devices, such as the LED lights on the Galahad AiO pump. This is in addition to the four ports supporting up to sixteen UNI FANs, in four groups of four. Lighting and fan control is achieved through the updated L-Connect 3 software from Lian Li or your motherboard's software for individual fans.
