As a new Pi owner, may i ask for some help. What fan are you using? Is there one that specifically connects to the GPIO port? Or any ole fan? and when you power the fan from the pins, do you need to set anything up? I'm using Octoprint to monitor my 3d printer, and i have NO idea how i would set things up if i had to (again, super new, as in got it yesterday, and hooked it up to my 3d printer this morning before work)

Thanks Rock!
