Jonsbo CA40 CPU Cooler PWM, RGB – black

The Jonsbo CA-40 Black is a compact CPU air cooler designed for space-saving gaming and office systems. With four heatpipes and a 120mm PWM fan, it delivers strong cooling performance while maintaining a slim design.

• 4 heatpipes – Efficient heat transfer for stable CPU temperatures.
• 120mm PWM fan – High airflow with automatic speed adjustment.
• Compact design – Suitable for mATX and ATX cases with limited space.
• Direct-contact base – Direct contact with the CPU for improved heat transfer.
• Wide socket compatibility – Supports common Intel and AMD platforms.

Compact performance with a 120mm fan

Despite its space-saving design, the CA-40 features a powerful 120mm fan. This ensures a strong, directed airflow through the heatsink, keeping the CPU reliably cool even under higher loads.

Efficient heat transfer

The four heatpipes quickly transfer waste heat from the processor to the aluminium fins. The direct-contact base absorbs and distributes heat efficiently, improving overall performance compared to basic standard coolers.

Quiet operation thanks to PWM

Thanks to PWM control, the fan speed automatically adjusts to the system temperature. In idle mode, the cooler operates pleasantly quietly, while under load the cooling performance increases as needed. This creates a balanced combination of performance and noise levels.
