Multi-function Cooling Expansion Board designed for the Raspberry Pi Features: 1.It is perfectly compatible with the Raspberry Pi 4B/3B+/3B and extends its life. It will not occupy any Raspberry Pi pin, not occupy heat sink space. 2. A 4pin IIC interface for 128 * 32 OLED display, which can real-time display CPU temperature, CPU usage, hard disk space, memory and IP address. 3. The large-size cooling fan on the board with strong wind power, it can make Raspberry Pi can run more stably by automatically adjust the speed according to the CPU temperature. 4. 3 high-brightness RGB programming lights on the bottom of the expansion board, which can realize following lights, breathing lights, marquees and so on. 5. It also expands Raspberry Pi 40pin header and can be used to connect to other devices. We will provide a driver package for all Raspberry Pi images, which is convenient for users to drive fans, OLED displays, RGB lights. Note: For Raspberry Pi 3B+ board. Even if 3B+ is not boot, as long as the USB is plugged in 3B+ board, the 3.3V pin will output 3.3V. If the Raspberry-Pi is abnormal, the 3.3V pin will have no voltage. Specification: Cooling board: Size: 61mm*59mm Weight: 34.1g Cooling fan: Size: 40mm*40mm Package Including 1 * Cooling HAT Expansion Board 4 * Copper Column 8 * Screw 1 * OLED Display

Supprisingly effective cooling system with super useful GPIO header
Incredibly easy to install, and lowers temperatures on my Pi under (realistic) loads to around 50-60celsius. The GPIO pin outs are also useful if you use the GPIO pins at all .. made attaching LEDs for power, net, drive functionality a trivial job. The blue light also looks extremely cool through the front of the server case I have my single board ARM machines in.Only drawback is that it is the fan is unnecessarily high off the ground and I had to remove the board I was using as mounting for the devices and mount directly to the 1U case I've got in order to provide enough space for the fan vs the top of the case. I doubt many people use 1U cases .. but it's worth bearing in mind the increased height profile if that will matter to you.

Good for me
Setup was a bit taxing. Disabled the strobe lights. Sorted start up at boot and perfect for me. Head scratching, Google, YouTube but big high when done.
