Fan LIAN LI SL FLEX 120 ARGB, reverse blade, black

Compact ARGB fan LIAN LI UNI FAN SL FLEX 120 (reverse blade) is a 120mm case fan with an "infinity" mirror and two lighting zones, designed for builds focused on aesthetics. It is suitable for desktop gaming and work PCs, where lighting synchronization and tidy cable management are important: the FLEX receiver combines power, RPM monitoring, speed control, and lighting in one module, while support for L-Connect 3 and synchronization with the motherboard provide flexibility in setting lighting and fan curves.

The reverse blades provide an inverted airflow direction compared to the standard version, which is useful in case configurations with bottom/side intake. The fan uses a fluid dynamic bearing (FDB), operates in the range of 350–2000 RPM, delivers an airflow of up to 66.5 CFM, and a static pressure of about 2.5 mmH2O — a combination suitable for both cases and radiators while maintaining a moderate acoustic level (≈29 dBA).
