240mm ARGB PWM fan Jonsbo ZB-240 Infinity Mirror — dual 120mm RGB fans for PC cooling

Jonsbo ZB-240 Infinity Mirror is a 240mm ARGB PWM fan solution consisting of two 120mm RGB fans designed for mainstream PC cooling. The set integrates Infinity Mirror ARGB effects with PWM-controlled motors to deliver adjustable airflow and acoustic balance. It is suitable for installation on radiators or in case front/top positions and provides synchronized lighting when connected to compatible ARGB headers or controllers.

Advantages

The dual 120mm fans offer a balance between static pressure and airflow, making them adaptable for radiator and chassis use. PWM control enables automatic speed adjustment based on system temperature or motherboard fan curves, helping to reduce noise during light loads. Infinity Mirror ARGB lighting produces layered visual effects that are visible from the fan face without compromising airflow. The fans use a standard mounting pattern compatible with most cases and radiators, and the integrated cables support common ARGB and PWM connections for synchronized control.

Suitable for

• 240mm liquid CPU radiators in gaming and workstation builds
• Front or top case intake/exhaust for improved chassis airflow
• Systems requiring synchronized ARGB lighting with motherboard or external controllers
• Upgrading stock case fans for better cooling performance and aesthetics

Key specifications

• Configuration: two 120mm fans, 240mm combined solution
• Lighting: Infinity Mirror addressable RGB (ARGB) effects
• Speed control: PWM for dynamic RPM adjustment
• Mounting: standard 120mm screw pattern for radiators and cases
• Connector types: ARGB header and PWM fan connector compatibility
• Performance focus: balanced static pressure and airflow suitable for radiators

How to use

Install each 120mm fan into the desired radiator or case location using the standard mounting holes and screws provided with your case or radiator. Connect the PWM fan connectors to a compatible motherboard fan header or fan controller to enable automatic speed regulation. Attach the ARGB cable to a compatible 5V addressable RGB header or ARGB controller to manage lighting effects. After mounting and connecting, verify fan orientation for correct airflow direction and configure fan curves and lighting profiles in firmware or software as needed.

Usage recommendations

For radiator installations, orient the fans to push air through the radiator fins toward the case or exhaust, depending on your cooling loop design. Use motherboard fan curves to balance cooling and noise, and ensure ARGB connections are to 5V addressable headers to avoid compatibility issues. Regularly clean fan blades and radiator fins to maintain performance.
