6 pure copper heat pipes with FIN technology. The heat pipes feature a double-row staggered design, with a thick, rounded curved section and a refined top sintering process. Increased fin density maximizes heat dissipation area, enabling dual heat conduction for faster and more efficient cooling. Equipped with a 4-pin 120mm fan with temperature control, utilizing hydraulic bearing technology and PWM temperature control design for high airflow and quiet operation. The fan speed automatically adjusts according to CPU temperature, providing intelligent and energy-efficient performance.SNOWMAN 4PIN CPU Cooler with 6 heat pipes and single 120mm fan.
