According to Moore's law, the design of high-speed and high-density printed circuit board (PCB) is becoming more and more complex. Higher processing performance will generate more heat. This super ICE Tower CPU Cooling Fan for Raspberry Pi is burned for solving heat dissipation problem! Tower structure, 5mm copper tube, multi-layer heat sinks, 7 blades powerful fan, all the above combinations make this super radiator for Raspberry Pi. In the case of overclocking, it can reduce the temperature of the Raspberry Pi from 80? to 40?. Best of all, this super cooling fan support both Raspberry Pi 3 and the new Raspberry Pi 4.
