Jonsbo ZA-240 Infinity Mirror ARGB 240mm PWM liquid cooler radiator with ARGB fans

The Jonsbo ZA-240 Infinity Mirror ARGB 240mm PWM liquid cooler radiator with ARGB fans is a compact all-in-one cooling assembly that combines a 240 mm radiator, two PWM-controlled fans and an infinity mirror pump cover with addressable RGB illumination. It is designed to improve CPU heat dissipation in desktop systems while offering customizable lighting effects driven by standard ARGB headers or included controller support. The combination of a slim 240 mm radiator and dual 120 mm PWM fans balances cooling performance and compatibility with mid-tower and full-tower cases.

Advantages

The infinity mirror pump cover provides a distinctive visual effect while addressable RGB LEDs enable per‑zone lighting control compatible with common motherboard software. PWM fan control allows dynamically adjusted fan speeds for quieter operation at low load and increased airflow under heavy CPU usage. The radiator and fan configuration is optimized for typical consumer and enthusiast processors, offering improved thermal transfer compared with air-only coolers in many scenarios.

Suitable for

• Gaming desktop PCs requiring enhanced CPU cooling and lighting integration
• Workstations with moderate to high CPU load where a 240 mm radiator fits the chassis
• System builders who want ARGB lighting and a compact liquid cooling solution

Key specifications

• Radiator size: 240 mm (dual 120 mm fan mounting)
• Cooling type: closed-loop liquid cooler with integrated radiator and pump
• Fans: two 120 mm PWM-controlled ARGB fans for variable speed and airflow
• Lighting: addressable RGB (ARGB) illumination in pump cover and fans
• Compatibility: supports mainstream CPU socket platforms (check motherboard header and chassis clearance)
• Materials: aluminium radiator with copper heat exchange paths in the block (typical for AIO designs)

How to use

Install the radiator and fans in a compatible case location that supports a 240 mm radiator, securing the fans in the recommended push or pull orientation for your airflow setup. Mount the pump/block onto the CPU with the supplied mounting bracket and thermal paste, ensuring even pressure and firm contact. Connect the pump power and the fans to the motherboard headers or included controller: attach PWM fan cables to the CPU_FAN or AIO_PUMP and ARGB cables to an addressable RGB header or controller. Configure fan curves and lighting profiles in the motherboard software or controller utility for balanced cooling and preferred illumination.

Recommendations

Ensure your case has sufficient clearance for a 240 mm radiator and confirm the presence of a compatible ARGB header or controller. Clean dust from the radiator fins and fans periodically to maintain airflow. Use motherboard fan control to set a suitable PWM curve: conservative at idle and more aggressive under sustained high temperatures to preserve component longevity and reduce noise. Avoid kinking tubing during installation and verify all cable connections before first power-up.
