How do I connect a Raspberry Pi 4 Fan?

On this page we explain how to connect the fan to your Raspberry Pi 4B. The Raspberry Pi 4 Model B has a much more powerful CPU than the previous models. Unfortunately, the heat dissipation has not been improved. This makes it almost necessary to connect an additional cooling. There are different types of cooling, but on this page we will talk about the fan . How do you connect a fan? And what actually happens if you do not connect a fan?

There are different forms of cooling for the Raspberry Pi 4. The different forms can be divided into two categories: passive cooling and active cooling. A form of passive cooling is, for example, a housing with a heatsink. The fan is a form of active cooling. Although fans are a lot quieter these days, they are not yet completely silent. If you have the Pi on your desk while working on a project, you will hear the fans. If you find that annoying, you might be better off opting for passive cooling.

1. The Raspberry Pi Board s have a row of GPIO Pins
2. Check out the pins in the picture below
3. You connect the fan to the selected pins at the top left if you want the fan to always be on. (as long as the Raspberry Pi is on)
4. The left pin is the 5V and the right is the GND.

If you don't have any cooling connected to your Raspberry Pi and you're working normally, you'll probably quickly get one of the two messages shown on the right of the screen.

From 80 degrees Celsius, the Raspberry Pi reduces its clock speed. If you ignore these warnings, it is possible that the Pi will shut itself down. With the right cooling, the Raspberry Pi can continue to work at top speed.
