Why design it?
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 designed for solving heat dissipation problem!

Features:
The super cooling fan can be used for Raspberry Pi 3B+ and Raspberry Pi 4B.
Super heat dissipation: 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℃.
The tower fan has 7 different color LEDs that change automatically, making your fan more beautiful and personalized. When the fan turns up, you will see the color of ice.
Easy to setup

Parameters:
DC 5V Power in (Can be powered by the Raspberry-Pi)
Rated power 0.4W 5V, 0.08A
background light : Blue Color

How to using it with Raspberry-Pi 3B+ and 4B?
1. Fixed the steel mounting fixer to radiator's heat dissipation cube with M2.0 screws
2. Fixed the steel mounting fixer to Raspberry-Piâ€s mounting hole with M2.5 copper stick, and please make sure the heat dissipation is contact to CPU shield properly.
3. Fixed the copper stick to Raspberry-Pi with M2.5 nuts.
4. Connect the red wire to GPIO 5V pin and black wire to GPIO GND pin.
