JONSBO ZA-240B 240mm 2x120mm ARGB case fan 2400RPM black

All-in-one 240 mm frame

The JONSBO ZA-240B is a black case fan assembly that mounts as a single 240 mm unit containing two 120 mm ARGB fans. A unified PWM and 3-pin ARGB connection lets the motherboard control speed and lighting for both fans together. The 28 mm thick frame includes an aluminium nameplate and four-sided infinity mirror illumination. It suits builders who want coordinated RGB and simplified cabling in a standard 240 mm mounting location.

Replaces dual-fan kits

Instead of installing two separate 120 mm fans with individual power and lighting cables, this module delivers the same airflow through one frame and one set of connectors. The upgrade is worthwhile when case space is tight or when a clean interior with fewer visible wires is a priority. Builders who need more than two fans in a single zone or who prefer mixing fan models will not be served by this fixed dual-fan design.

Sustained 2400 RPM operation

At full speed the fans reach 2400 RPM while producing static pressure between 0.49 and 2.46 mmH2O, maintaining consistent airflow through radiators or dense mesh during extended loads. PWM regulation allows the motherboard to lower speed and noise when thermal demand drops. The single-frame construction keeps both fans mechanically aligned, preventing vibration drift that can appear when separate fans age at different rates.
