1. Two pure copper heat pipes wear FIN technology. The heat pipe adopts a double-row staggered design, the curved part is and thick, and the top sintering process is exquisite. 2. The bottom HDT technology, the bottom distance is in contact with the CPU, heat dissipation is faster and more effective. 3. High-efficiency silent fan adopts hydraulic technology, air volume and no noise. 4. It can better suck cold air into the CPU, quickly take the temperature of the hardware around the motherboard, and effectively reduce the CPU temperature. 5. Humanized design, suitable for 90% of the market's chassis, home, office, Internet cafes, server products.
