>From the label, it looks like a brushed motor which would be much easier than a DC brushless motor however brushed motors only have two wires, the third may be a sensor wire to the control circuitry in the laptop could change the speed of the motor. With that said, you would just need a 5V DC supply to power it. If you want it to have variable speed control you would need a PWM circuit which you can set up with an Arduino or an RPI. ~Carl
