6 FIN wear pure copper heat pipe technology. The heat tube adopts staggered double-row design, the curved part is round and thick, and the top of the sintering process is exquisite. Increase fin group, maximize heat dissipation area, double heat conduction, faster, more effective heat dissipation 4 pin 12 CM temperature controlled fan, using hydraulic technology and PWM temperature control design, large air volume and quiet. Fan speed will change according to CPU temperature, which is smarter and more energy efficient.
