3 copper pipe and 2 fan design. 3 Copper tube design, more than enough to solve the CPU35W power consumption. Dual fans can meet the heat dissipation requirements of low speed, low noise and high air volume. Under 100% load, the CPU temperature is constant at 61℃, and the performance of the whole line of delivery machines.
