Jonsbo CB40 CPU Cooler, PWM, ARGB - black
The Jonsbo CB-40 Black is a powerful tower CPU air cooler designed for gaming and all-round systems. With four heat pipes and a 120mm PWM fan, it offers reliable cooling performance while maintaining a slim design.
- 4 heat pipes – Efficient heat transfer for stable CPU temperatures under load.
- 120mm PWM fan – High airflow with automatic speed adjustment.
- Direct-contact base – Direct contact with the CPU for improved heat transfer.
- Aluminium heatsink – Large surface area for effective heat dissipation.
- Wide socket compatibility – Supports common Intel and AMD platforms.
Efficient Tower Cooling
The tower design ensures targeted airflow through the aluminium fins. The four heat pipes quickly transport heat away from the processor, keeping temperatures stable even during intensive use.
Powerful 120mm Fan
The integrated 120mm fan generates strong airflow for optimal cooling performance. Thanks to PWM control, the fan speed automatically adjusts to the system temperature, achieving a balanced ratio between performance and noise.
Sleek Design for Versatile Builds
With its black finish, the CB-40 blends seamlessly into a variety of systems. It is suitable for gaming PCs as well as high-performance everyday computers. Functionality and clean design are the main focus here.
