## Long description

Jonsbo ZA-420 Black PWM ARGB is a set of three 140 mm PWM addressable RGB fans configured for a 420 mm array. Designed for PC case airflow or use on a compatible 420 mm radiator, the fans combine adjustable PWM speed control with synchronized ARGB lighting for integration with motherboard headers that support 3-pin ARGB and PWM fan control. The black frame and blades provide a neutral aesthetic suited to many builds while the ARGB ring delivers customizable lighting effects when connected to a compatible controller or motherboard software.
Advantages
The ZA-420 set offers precise speed regulation through PWM control, allowing quiet operation at low loads and higher airflow when needed. Addressable RGB LEDs enable per-fan lighting customization and synchronization across the three fans. The 140 mm fan size provides a balance between airflow and noise, and the included 420 mm arrangement is suitable for larger cases and multi-fan radiators. Simple connector compatibility with standard motherboard headers reduces installation complexity.
Suitable for
 Case airflow upgrade for mid-tower and full-tower PC cases supporting 420 mm fan arrays
 Cooling large 420 mm liquid radiators with three 140 mm fans
 Systems requiring addressable RGB lighting synchronized with motherboard software
 Builds where PWM fan speed control is needed for automated thermal management
Key specifications
 Fan size: 140 mm per fan
 Configuration: set of three fans for 420 mm arrangement
 Speed control: PWM compatible with motherboard fan headers
 Lighting: addressable RGB (ARGB) per fan for synchronized effects
 Frame color: black
How to use
Install the three fans in the 420 mm mounting positions of your PC case or on a compatible 420 mm radiator, aligning screw holes and securing with appropriate screws. Connect each fan's PWM power cable to the motherboard fan headers or a PWM hub to enable automatic speed control. Attach the ARGB connector to a 3-pin addressable RGB header or ARGB controller to enable lighting control. After physical installation, configure fan curves and ARGB effects through your motherboard software or external controller to match your thermal and aesthetic preferences.
Usage recommendations
For optimal results, place the fans to establish a consistent airflow direction (intake or exhaust) and configure PWM profiles to balance cooling performance and noise. Ensure your motherboard or controller supports 3-pin ARGB and PWM fan control for full functionality. Regularly clean dust filters and fan blades to maintain airflow and lighting clarity.
