This automatic fan control module allows you to determine the exact CPU temperature to automatically turn your fan on! Place the module on your Raspberry Pi's GPIO header (on pins 1-8), connect your fan to the connector on the top, then run the quick setup detailed below - no coding required!\u003c\/p\u003e\n\u003cp\u003eThis control module consumes GPIO pins 1-8 (5V, I2C and GPIO14) and \u003cstrong\u003ealso breaks out the 3.3V, 5V, I2C, TXD and RXD lines\u003c\/strong\u003e for use with components in your project. We also have simpler alternative versions - see below.\u003c\/p\u003e\n\u003cp\u003eThe fan connector accepts a 2.54mm female fan connector (jumper wires) or JST connection.\u003c\/p\u003e\n\u003cp\u003eThis module is compatible with the LeapMatic MaticBox case with the Automation cover.

Select Fan GPIO 4 and the temperature at which you want the fan to turn on. Save with OK.\u003c\/p\u003e\n\u003cp\u003eWhen the processor reaches the temperature you set, the fan will turn on. It will turn off when the processor temperature drops 10 degrees below the set temperature. (For example, if you set the 'on' temperature to 75 degrees, the fan will turn off when the processor reaches 65 degrees).\u003c\/p\u003e\n\u003cp\u003eWith these few easy steps, you now have automatic fan control!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOption 2 - via Terminal\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOpen a new terminal window and type the following command, followed by Enter:\u003c\/p\u003e\n\u003cpre\u003esudo raspi-config\u003c\/pre\u003e\n\u003cp\u003eThis will open a graphical menu where you need to choose Performance Options \u0026gt; Fan.
