Jonsbo CA-90 black CPU cooler: dual tower with maximum cooling performance The Jonsbo CA-90 black is a powerful CPU air cooler for demanding gaming and high-end systems. With dual tower design, six heat pipes and a 120-mm and 130-mm PWM fan, it offers high cooling performance for modern processors. The combination of two fans of different sizes ensures optimised airflow and efficient heat dissipation. The direct-contact base allows direct transfer of CPU heat to the heat pipes, thus improving overall performance. Thanks to PWM control, both fans automatically adapt to the system load and ensure quiet operation in everyday use as well as maximum cooling performance when needed. Ideal for high-performance rigs with a focus on stability, efficiency and low noise.
