How to use Raspberry Pi GPIO pins with Ubuntu Tutorials Ubuntu
Raspberry Pi configuration allows you to set the temperature to control raspberry pi fan on/off. But there is a limitation to it. It only allows you to set temperature from 60 degree to 120 degree.. Connect Raspberry PI fan to GPIO PIN 14(default). Other 2 pin is to +5v and GND. Download the python script from https://github.com.
How can I adjust the fan speed on Raspberry Pi 4B? Raspberry Pi Forums
to reduce fan noise: hardware method: change the fan software method: use PWM control (requires hardware components as well) "Don't come to me with 'issues' for I don't know how to deal with those Come to me with 'problems' and I'll help you find solutions" Some people be like: "Help me! Am drowning! But dont you dare touch me nor come near me!"

Select Performance Options > Fan, and follow the prompts to enable temperature control. Select the GPIO pin, and select at which temperature it should come on (between 60 and 120ºC, which is the same on the GUI interface). It then asks you if you want to reboot, and once that is done, the fan is temperature activated.
Temperature Controlled Fan for Raspberry Pi 4 Fizzy
In order to control the fan, we need to use a transistor that will be used inopen collector configuration. By doing this, we have a switch that will connect or disconnect the ground wire from the fan to the ground of the raspberry pi. A NPN BJT transistor conducts depending on the current that flows in its gate. The current that will be allowed.

If your fan is a 3v fan DO NOT use the 5v pin: use 3v instead. Raspberry pi has an utility called pinout which tells you the phisical layout of your board. Just open a shell and run: pinout. The output will be something like: If you prefer to trust documentation, this is the layout the documentation states: Left side first or second pin for 5v.
