Hello PCPP community! I have a question that's been bugging me: I know how CPU fans work: you mount them (varies per fan) but I wonder how do Case Fans work? Is there a cord that powers them? I know you have to mount them but how do they actually spin so that they cool my PC? Take this build as an example: http://uk.pcpartpicker.com/p/cmXBgs
Those case fans: how dafuq will they start spinning?! Also do the cases come with preinstalled fans? If so is it necessary to buy aftermarket ones?
FYI: If you hadn't noticed already, I'm a noob.
