My MacBook Air 2013 is routinely the loudest machine in the room when it's compiling or similar.

  Does it have fans? If not, what kind of noise is this ?

    MBAs have fans, the 12" MacBook doesn't.

    Possibly inductors vibrating.

    "Coil whine".

      No, the sound comes mostly from the fans, which when at their maximum start to get loud.
