AIO Liquid CPU Cooler Jonsbo TH-240B 240mm with ARGB Display

The Jonsbo TH-240B is an all-in-one 240mm liquid CPU cooler with an integrated ARGB display built into the pump housing. It pairs a 240mm aluminum radiator and two PWM-controlled fans with a compact pump block that features a customizable ARGB screen. The design targets efficient heat transfer from modern desktop processors while offering visual customization through addressable RGB lighting and a display interface that can show images, system information, or preset animations.

Advantages

The TH-240B delivers improved thermal performance compared with many stock air coolers thanks to a 240mm radiator surface area and dual fans that increase airflow through the fins. The pump unit with an ARGB display centralizes lighting and simple visual monitoring without separate accessories. PWM fan control enables automatic speed adjustment to balance cooling performance and noise. The compact pump and flexible tubing simplify installation in cases that support 240mm radiators.

Suitable for

• Cooling gaming desktop CPUs under sustained loads
• Workstations for video editing, 3D rendering and content creation
• Small- to mid-tower builds with support for 240mm radiators
• Systems where ARGB lighting and a customizable display are desired

Key specifications

• Radiator size: 240mm dual-fan configuration
• Cooling method: closed-loop liquid cooling with integrated pump
• Fans: dual PWM-controlled ARGB fans for variable speed and lighting
• Pump: compact pump head with integrated customizable ARGB display
• Tubing: flexible, durable tubing for standard AIO routing
• Compatibility: supports common desktop CPU sockets on modern motherboards (check case and socket compatibility before installation)

How to use

Install the radiator in a compatible location inside the PC case, typically at the top or front where there is space for a 240mm radiator and two fans. Secure the radiator and fans according to the case mounting points, following the fan orientation recommended for intake or exhaust airflow in your build. Mount the pump block on the CPU using the supplied mounting brackets and backplate, align it over the CPU IHS, and fasten evenly to ensure consistent contact. Connect the pump power and ARGB/display control cables to the designated motherboard headers or controller, and connect the fan cables to PWM headers or a hub for synchronized speed control. After assembly, power on the system, enter BIOS or use software to confirm pump and fan operation, and configure ARGB lighting and the display content per the motherboard or controller software.

Recommendations

Place the radiator where case airflow is least obstructed and maintain regular dust cleaning on fan and radiator surfaces. Use motherboard utilities or fan control software to set a PWM profile that balances noise and temperature for your workload. Verify compatibility with your CPU socket and case radiator clearance before purchase and refer to the included manual for torque specifications and mounting order. For stable ARGB display operation, ensure proper connection to the display/ARGB header and update any required software or firmware for full customization.
