Description

The Jonsbo CB-40 Black is a powerful tower CPU air cooler for gaming and all-round systems. With four heat pipes and a 120-mm PWM-fan it offers reliable cooling performance with a simultaneous slim design.

Efficient tower cooling
The tower design provides targeted air circulation through the aluminum fins. The four heat pipes transport the waste heat quickly away from the processor. This allows temperatures to remain stable even in intensive applications.

Powerful 120 mm fan
The integrated 120-mm fan generates a strong air current for optimum cooling power. Thanks to PWM regulation the speed adjusts automatically to the system temperature. In this way a balance between performance and volume is achieved.

Simple design for versatile builds
With its black appearance, the CB-40 fits seamlessly into various systems. It is suitable for gaming-PCs as well as for powerful daily computing. Functionality and clear design are of primary importance.
