FAN Jonsbo ZB-120, 120 mm, ARGB, 28 mm

The Jonsbo ZB-120 is a 120 mm chassis fan with addressable 5V ARGB lighting and PWM speed control. Available in standard and reverse‑blade variants, the fan is 28 mm thick, making it compatible with most case mounts and many compact radiator setups. It’s aimed at builds that want a combination of visible ARGB effects and effective airflow.

The ZB‑120 uses a 4‑pin PWM connector for fan speed control and a 3‑pin 5V ARGB connector for addressable lighting. Key performance figures (RPM range, airflow and noise) differ between the regular and reverse‑blade SKUs, so choose the variant that matches your airflow/pressure needs. Typical uses include intake/exhaust positions in cases, slim AIO/radiator mounting and replacing noisy stock fans for better airflow and lighting.
