CPU Cooler Jonsbo CB80 Dual-Tower with 2 x 120mm PWM RGB Fans — black

The Jonsbo CB80 Dual-Tower CPU Cooler with two 120mm PWM RGB fans is a tower-style air cooler engineered for desktop systems that need enhanced CPU heat dissipation and addressable RGB lighting. The design uses a dual heatsink tower layout paired with two 120mm fans that support PWM control, allowing fan speed to vary with CPU temperature to balance cooling performance and acoustic output. ARGB lighting is integrated into the fans to provide customizable visual effects when connected to a compatible motherboard or controller.

Advantages

The dual-tower heatsink increases the surface area available for heat transfer, enabling more effective cooling compared with single-tower designs of similar footprint. Two 120mm PWM fans provide flexible speed control and better airflow across the heatpipes and fins, while ARGB illumination offers visual customization for system builds. The cooler is supplied in a black finish intended to integrate with a variety of case interiors.

Suitable for

• Mid- to high-performance desktop CPUs requiring improved air cooling
• Systems where adjustable fan speed and quieter operation under light load are desired
• PC builds that use ARGB lighting for coordinated aesthetics
• Cases with standard top or front fan mounting clearances that accommodate dual-tower coolers

When it may not be suitable

This dual-tower cooler may be unsuitable for very compact or small-form-factor cases where internal clearance is limited, particularly in slim HTPC or mini-ITX enclosures. It may also interfere with tall memory modules or certain motherboard VRM heatsink layouts on some boards unless clearance is verified before purchase.

Key specifications

• Cooling type: Dual-tower air cooler
• Fan configuration: 2 × 120mm PWM fans
• Lighting: Addressable RGB (ARGB) on fans
• Fan control: PWM for automatic speed adjustment based on temperature
• Finish: Black
• Compatibility: Designed for standard desktop CPU sockets (verify socket support with manufacturer)

How to use

Install the cooler according to the included mounting instructions for your motherboard socket. Apply a thin, even layer of thermal paste to the CPU surface before seating the cooler. Secure the mounting bracket and fasten the cooler evenly to ensure full contact between the base and CPU heatspreader. Connect the fan PWM cables to the CPU_FAN or AIO_PUMP header and the ARGB connectors to a compatible ARGB header or controller. Verify fan operation and lighting in BIOS or using motherboard software, and monitor CPU temperatures during initial use to confirm correct installation.

What to consider before purchase

• Check case internal clearance and cooler height to ensure fitment
• Verify RAM height and potential interference with the dual-tower layout
• Confirm motherboard socket compatibility and mounting hardware included
• Ensure your motherboard or controller supports ARGB headers if you want lighting control

Recommendations

For optimal results, position intake and exhaust case fans to create a consistent airflow path across the dual towers. Use motherboard fan curves or software to set PWM profiles that allow the cooler to run quietly at low loads and increase fan speed under sustained CPU demand. Confirm clearance around memory modules and adjust fan positions if necessary to avoid contact while maintaining airflow.
