your red and black should be connected directly to power, and your blue wire connected to the ground of PA0
red and black are in pin: PA1, is connected to the power ?
it is a IO pin, you want an always on pin (or direct to power) The blue wire is for PWM and is how you control the fan - that is the one you want to attach to a IO pin
