## Summary description

Jonsbo ZA-420BR is a set of three 140 mm PWM-controlled reverse-rotation ARGB case fans in black. Designed for chassis cooling, they provide adjustable speed via PWM and addressable RGB lighting for customizable illumination. Suited for improving airflow in PC builds, radiator cooling, and quiet operation depending on system fan control.

## Long description

Jonsbo ZA-420BR is a set of three 140 mm PWM-controlled reverse-rotation ARGB case fans in black, designed to improve chassis airflow and provide customizable lighting. Each fan supports PWM speed control for seamless integration with motherboard fan headers or dedicated fan controllers, while addressable RGB (ARGB) LEDs allow per‑fan lighting effects when connected to a compatible ARGB controller or motherboard header. The reverse-rotation blade design helps optimize airflow patterns in multi-fan configurations and radiator setups, making the set suitable for a variety of PC cooling tasks.
Advantages
The ZA-420BR bundle combines large 140 mm fan blades with PWM control to deliver efficient airflow at lower RPMs, reducing noise compared with smaller high‑speed fans. Reverse-rotation blades are engineered to complement standard fans in push/pull or intake/exhaust arrangements, improving overall cooling performance. Integrated addressable RGB lighting provides flexible illumination options and synchronizes with common ARGB software when connected to supported headers or controllers.
Suitable for
 ATX, microATX and Mini-ITX desktop PC cases requiring 140 mm fan mounts
 Case airflow optimization in multi-fan or push/pull radiator configurations
 Silent or low-noise builds where PWM control is used to manage fan speed
 Systems requiring customizable ARGB lighting synchronized with motherboard software
Key specifications
 Fan diameter: 140 mm
 Control: PWM speed control compatible with standard 4‑pin headers
 Lighting: Addressable RGB (ARGB) per fan for individual LED effects
 Design: Reverse-rotation blade profile for optimized airflow patterns
 Color: Black frame and blades
 Bundle: Pack of three matched fans for consistent performance
How to use
Install the fans in available 140 mm mounting positions in the chassis, observing airflow direction markings or the intended intake/exhaust orientation. Connect the 4‑pin PWM cable to a compatible motherboard fan header or PWM hub to enable automatic speed control based on system temperatures. Attach the ARGB connector to a compatible addressable RGB header or controller to control lighting; consult your motherboard or controller manual for pinout and software setup. Secure each fan with the supplied screws or appropriate mounting hardware and route cables to maintain clearance from moving parts and airflow paths.
Usage recommendations
For optimal cooling and stable ARGB control, connect PWM and ARGB cables to the motherboard headers when available. When using multiple fans on one header, ensure the combined current draw is within the header or hub specifications. Position reverse-rotation fans to complement standard fans in push/pull radiator setups to improve static pressure and airflow balance. Use motherboard fan curves or software to set target RPM ranges that balance temperature and noise for your setup.
