Koelventilator Jonsbo ZA-120 Reverse Blade PWM ARGB 120mm wit

The Jonsbo ZA-120 Reverse Blade PWM ARGB 120mm White is a case and cooler fan designed to deliver directed airflow with a reverse-blade design and integrated addressable RGB lighting. Equipped with PWM speed control, the fan adapts to system cooling requirements while the ARGB connector supports lighting synchronization with compatible motherboards and controllers. Its white frame and blades provide a neutral aesthetic that complements a wide range of builds while focusing on airflow efficiency and adjustable illumination.

Advantages

The reverse-blade geometry is intended to optimize airflow direction and pressure for improved ventilation in constrained chassis environments. PWM control enables automatic fan speed adjustment based on motherboard or fan hub signals, reducing noise at low load and increasing cooling when required. The ARGB lighting offers per-LED color effects and synchronization options with standard 3-pin ARGB headers, allowing coordinated lighting across components. The white finish helps maintain a clean visual appearance in both light and dark system themes.

Suitable for

• Case ventilation to improve overall system airflow
• CPU cooler fan replacement or upgrade
• Systems requiring synchronized ARGB lighting
• Compact or mid-tower builds where directional airflow and static pressure matter

Key specifications

• Fan size: 120 mm
• Blade design: reverse-blade for directed airflow and pressure characteristics
• Speed control: PWM (pulse-width modulation) for automatic RPM adjustment
• Lighting: Addressable RGB (ARGB) with 3-pin standard header compatibility
• Frame color: white
• Connector types: PWM power connector and separate ARGB signal connector

How to use

Install the fan into a compatible 120 mm mounting location in the case or on a CPU cooler using the supplied screws or appropriate mounting hardware. Connect the PWM power cable to a motherboard fan header that supports PWM control to allow automatic speed regulation. Connect the ARGB cable to a compatible 3-pin ARGB header or controller to enable lighting effects and synchronization. After installation, configure fan curves and ARGB effects through the motherboard or controller software to match cooling and aesthetic preferences.

Recommendations

Ensure the fan is oriented to achieve the intended airflow direction in your case; reverse-blade geometry may affect expected intake/exhaust behavior compared with standard fans. Verify motherboard header pinouts and controller compatibility before connecting the ARGB cable. Clean the fan periodically to maintain performance and check mounting stability to avoid vibration.
