Now connect the fan to the lower two pins on the right side of the board.

The red cable must be connected to the + pin and the black cable to the

pin.

You can either connect the fan permanently to 5V, which will cause it to

rotate continuously at full power, or you can control the fan speed with a

PWM signal, which allows you to make the fan speed dependent on the

CPU temperature of the Raspberry Pi.

To do this, set the jumper on the right side to either 5V or PWM.

A Python script for PWM fan control can be found at the end of this manu-

al.
