The Argon Fan HAT is a simple Raspberry Pi HAT that cools the Pi and gives it a safe shutdown button. With just a one-line script, you'll have full functionality for the HAT, allowing you to do additional features such as rebooting the pi, and adjusting the fan speed of the single board computer. You can even program when the fan adjusts its speed, giving you full control over the HAT. Get ready to use this in any Raspberry Pi Case that offers HAT support, such as the Argon POLY+ or the Argon NEO. The best part is that this will work for the Raspberry Pi 4 Model B, the Raspberry Pi 3 Model B, and the Raspberry Pi 3 B+.
