LIAN LI UNI FAN SL-INFINITY 120 mm Black 3-Pack Case Fan

The LIAN LI UNI FAN SL-INFINITY 120 mm Black 3-Pack UF-SLIN120-3B is a case-cooling set intended for computer cases that accept 120 mm fans. Its top rotational speed is 2,100 RPM, giving a specified maximum airflow of 61.3 CFM. Static pressure reaches 2.66 mmH₂O, which matters when moving air through moderately restrictive areas. At full speed, the rated noise level is 29 dB. PWM support allows fan speed to be adjusted rather than fixed at maximum output. Together, these ratings suit general chassis ventilation and focused airflow where some resistance is present.

Each fan uses a fluid dynamic bearing for smooth operation. The modular frames interlock, allowing multiple fans to be joined while reducing the number of cables routed through the case. Integrated multicolour ARGB lighting uses an infinity-mirror design to create a coordinated visual effect. A UNI HUB SL-INFINITY ARGB controller is supplied for lighting management, and the required cables are included with the three-fan package. Fan operation and lighting use separate connections, which is worth bearing in mind when checking available headers during installation.
