Fans are useful devices that create airflow to cool something down provide a fresh supply of air or help the circulation of aerosols. Add a fan to a raspberry pi 3 with control to turn it on and off as required an easy way to add a fan is to simply connect the fan leads to a 3 3v or 5v pin and to ground. This project uses the official raspberry pi 4 case though you can use any other case to accomplish this project as well. Most domestic fans have different speed settings but these are often in the form of mechanical buttons which may be difficult to control using a raspberry pi.

There is no way to control safely any motor directly from a pi gpio. Gpiopin gpio used to control the fan default 12 temp temperature at which the fan switches on in millicelcius default 55000. The raspberry pi foundation released an official raspberry pi 4 desktop kit. The desktop kit includes the official raspberry pi 4 case which is an enclosed plastic box with nothing in the way of ventilation.

A raspberry pi enthusiast jeff geerling released a pretty cool video showing how to add a fan to the raspberry pi to help keep the temperature under control.

However the fan is controlled with an rf remote control which isn t as easy to spoof as an ir remote.

The pi gpio are all 3v3. The back emf generated by a collapsing motor field can destroy the gpio and the pi. This truly makes the raspberry pi a workable personal portable computer. Hope you enjoy with it.
