Fan LIAN LI SL FLEX 120 (3 pcs), black

The LIAN LI UNI FAN SL FLEX 120 (3‑pack) — a set of three 120 mm modular ARGB case fans from the FLEX series featuring daisy‑chain connectivity via a compact FLEX receiver. Lighting and fan speed can be controlled with L‑Connect 3 or synced to the motherboard (5V ARGB + PWM); the 3‑pack includes an L‑Wireless controller for wireless management.

Designed for balanced airflow, static pressure and low noise, each fan runs up to 2000 RPM, delivers up to 66.5 CFM and produces about 29 dBA (standard blade). The FLEX receiver simplifies cable routing and RPM reporting (each receiver supports up to four matching fans), making the set suitable for front intake, radiator mounting and ARGB‑accented system builds.
