JONSBO ZA-120W 140mm ARGB case fan

140mm ARGB Infinity Mirror Fan

The JONSBO ZA-120W is a 140mm white case fan built around a four-sided infinity mirror design that creates a layered visual effect. It targets builders who want addressable RGB lighting synchronized through a standard 3-pin 5V header without needing a separate controller. The 28mm thick frame houses an aluminium CD-pattern nameplate and uses a joint structure intended to simplify installation in compatible cases.

Airflow Range and Acoustic Limits

The fan spins between 700 and 2400 RPM, delivering 20.95 to 65.26 CFM of airflow with a static pressure range of 0.45 to 3.20 mmH2O. Noise output spans 20.3 to 36.6 dB(A) across the speed curve. At the lower end the unit runs quietly for idle or light workloads; at maximum speed it moves significantly more air but becomes audible, so it suits builds that can trade some noise for thermal headroom rather than strictly silent operation.

PWM and ARGB Connector Practicalities

A single 4-pin PWM header controls motor speed while a 3-pin 5V ARGB header handles lighting, both connecting directly to the motherboard. The integrated male and female connectors allow daisy-chaining multiple fans on one cable run, reducing cable count. Builders whose boards lack a 5V ARGB header cannot use the lighting sync feature, and systems without PWM support lose automatic speed control, relying instead on fixed voltage regulation.
