## Summary description

Set of three Jonsbo ZA-420WR 140 mm case fans in white with PWM speed control and Reverse ARGB lighting. Designed for PC cooling, the 3×140 mm configuration provides airflow and noise management for chassis, radiators or CPU coolers. PWM enables automatic speed adjustment for temperature-based performance; ARGB offers customizable lighting effects.

## Long description

The Jonsbo ZA-420WR 3×140 mm PWM Reverse ARGB White fan set is a trio of white 140 mm case fans engineered for chassis ventilation, radiator cooling and targeted airflow. Each fan supports PWM speed control for automatic adjustment based on thermal load, while Reverse ARGB lighting provides addressable, directionally inverted illumination compatible with standard ARGB controllers. The 3×140 mm configuration balances higher static pressure and airflow with reduced rotational speed to help control noise during sustained operation.
Advantages
The fans combine PWM regulation and large-diameter blades to deliver adaptable cooling performance and quieter operation at lower RPMs. Reverse ARGB lighting enables synchronized color effects without altering airflow characteristics. The white finish integrates with light-themed builds and helps diffuse RGB tones for a uniform look. The set includes three matched fans for consistent airflow and lighting behavior across multiple mounting positions.
Suitable for
Front, top or rear chassis fan mounts in mid-tower and full-tower PC cases
140 mm radiator or liquid cooler setups requiring balanced airflow and pressure
Airflow optimization for CPU cooler shrouds and case intake/exhaust configurations
Builds with ARGB control systems for synchronized lighting effects
Key specifications
Fan size: 140 mm diameter
Set quantity: 3 fans
Control: PWM speed regulation for automatic RPM adjustment
Lighting type: Reverse ARGB (addressable RGB with reverse orientation)
Frame color: White
Connector types: standard PWM power connector and ARGB header compatible with 3-pin addressable RGB controllers
Mounting: 4-point screw mount for standard 140 mm fan locations
How to use
Install each fan in the desired chassis locations using the supplied mounting screws or vibration-damping fasteners, observing the indicated airflow direction printed on the fan frame to establish intake or exhaust orientation. Connect the PWM power connectors to the motherboard or a fan hub that supports PWM control to enable automatic speed scaling. Attach the ARGB connectors to a compatible 3-pin addressable RGB header or controller to manage lighting effects. Verify cable routing does not obstruct blades or other components and perform a system reboot to confirm PWM and ARGB functionality in BIOS or lighting software.
Usage recommendations
For balanced cooling and acoustic performance, configure one or two fans as intake and the remainder as exhaust to maintain moderate positive or neutral case pressure. When mounting on a radiator, place fans so that the blades push air through the radiator fins in the intended direction; use the motherboard or controller software to set PWM fan curves based on system temperatures. Clean fans periodically from dust buildup using compressed air while the system is powered down.
