4 pure copper heat pipes with FIN technology. The heat pipes feature a double-row staggered design, with thick rounded curved sections and an advanced sintering process for enhanced thermal performance. Increased fin density maximizes heat dissipation area, enabling dual heat conduction for faster and more efficient cooling. Equipped with a 120mm 4-pin fan with PWM temperature control and hydraulic bearing technology, delivering quiet operation and optimized airflow. Ideal for home, office, internet cafes, and server environments. CPU cooler with direct contact heatpipes, designed as a tower-style cooling system with dual fans and PWM support.
