Connectivity and Control Comparison
Lighting Control
The Lian Li UNI Fan SL-Infinity 120mm relies on a physical controller included in the triple pack. This hardware hub manages up to 16 fans and supports two additional SM-type connecting devices. You customize lighting through this dedicated unit, which handles the 40 LEDs per fan. In contrast, the Lian Li UNI Fan CL120 Wireless uses a 2.4 GHz wireless receiver. This eliminates physical cabling for data, allowing you to manage fan speed and RGB effects without tangled wires. The wireless approach offers a cleaner internal look compared to the wired controller of the SL-Infinity.
Software Integration
Control methods differ significantly between these two models. The SL-Infinity 120mm provides customizable lighting effects through its included controller, allowing you to choose from pre-set combined options or individual modes for the blades and frame. There is no mention of PC software integration in its specifications. The CL120 Wireless, however, integrates with L-Connect 3 software. This allows you to gain complete control over fan settings, RGB presets, and light zones from your computer. If you prefer managing your build aesthetics through a desktop application rather than a physical button box, the CL120 is the superior choice.
Blade Configuration
Airflow direction is a critical spec for radiator compatibility. The Lian Li UNI Fan CL120 Wireless is explicitly listed as a reverse blade configuration. This design optimizes airflow for specific mounting scenarios, such as pushing air through radiators in certain orientations. The SL-Infinity 120mm data does not specify a reverse blade design. However, it does mention a reversible cable module and removable keylock for improved radiator compatibility. While the CL120 offers a dedicated reverse blade option for precise airflow direction, the SL-Infinity focuses on cable management flexibility for radiator fittings.
Airflow Performance
Performance specifications provide insight into cooling capability. The Lian Li UNI Fan CL120 Wireless lists a maximum speed of 2100 RPM and a static pressure of 2.38 mm H2O for the reverse blade version. Normal airflow reaches 2150 RPM with 2.52 mm H2O. The fan thickness is optimized at 28mm for efficiency. The Lian Li UNI Fan SL-Infinity 120mm data does not provide RPM or static pressure values. It focuses on the visual infinity mirror design and LED count. Without performance numbers, you cannot compare cooling potential directly, but the CL120 offers transparent technical metrics.
Lighting Design
Visual aesthetics are a primary feature for both units. The SL-Infinity 120mm features an all-around infinity mirror design with 40 LEDs per fan. This creates a multi-layer effect visible from any angle, emphasizing the frame and blades. The CL120 Wireless offers two distinct light zones. Zone 1 illuminates the fan blades for a striking appearance, while Zone 2 provides a smooth, diffused glow on both sides of the fan. Both models support ARGB or customizable lighting, but the SL-Infinity emphasizes the infinite reflection effect, whereas the CL120 focuses on dual-zone diffusion.
