Cooling fan Jonsbo ZB-120 Reverse Blade PWM ARGB 120mm White, axial fan, 120 mm

Jonsbo ZB-120 Reverse Blade PWM ARGB 120mm White is a 120 mm axial cooling fan designed for PC cases and radiators. The fan combines a reverse-blade impeller with PWM speed control and addressable RGB illumination to provide adaptable airflow, quiet operation when needed, and synchronized lighting effects. The white frame and blades integrate with light-colored builds or create contrast in darker systems while supporting motherboard-based ARGB control for coordinated visual setups.

Advantages

The reverse-blade design alters airflow patterns compared to conventional fans, which can improve static pressure characteristics for radiator use while maintaining effective case ventilation. PWM control enables automatic speed adjustments based on motherboard fan headers or fan controllers, balancing cooling performance and noise levels. Addressable RGB lighting provides per-LED color control for synchronized effects when connected to a compatible ARGB header. The 120 mm size makes the fan compatible with standard mounting points found in most PC cases and cooling solutions.

Suitable for

• Case ventilation in desktop PC builds
• Mounting on liquid-cooling radiators requiring high static pressure
• Systems with motherboard PWM and ARGB headers for synchronized control
• Builds seeking a white aesthetic or contrasting fan appearance

Key specifications

• Fan type: axial, 120 mm diameter
• Blade design: reverse-blade impeller for altered airflow characteristics
• Control: PWM speed control compatible with motherboard fan headers
• Lighting: addressable RGB (ARGB) per-LED control when connected to appropriate header
• Frame color: white
• Mounting: standard 120 mm screw pattern for cases and radiators

How to use

Install the fan using the standard 120 mm mounting holes in your PC case or on a compatible radiator, aligning the airflow direction with your intended cooling layout. Connect the 3- or 4-pin PWM power connector to a compatible motherboard fan header to enable automatic speed control, and attach the ARGB cable to a compatible addressable RGB header for lighting control. After installation, configure fan curves and lighting profiles in your motherboard firmware or control software to match desired cooling performance and visual effects.

Recommendations

For radiator installation, orient the reverse-blade fan so that airflow is directed through the radiator fins toward exhaust or intake as required by your cooling loop; use PWM control to maintain higher RPM under load and lower RPM at idle. Ensure ARGB headers and software support addressable RGB devices to access full lighting customization. Periodically clean dust from the blades and frame to preserve cooling efficiency and maintain balanced operation.
