When I turn on the phantom, it seems like there is a buzzing and fan that is running. I've watched a number of YouTube videos and havent heard this from any of the Phantoms... Clues? Do I have a bad Phantom? Its new and just out of the box... I'm attaching a recording I took of the noise. As I can't upload a mp4, I named the file with a .TXT extension. Remove that to hear what I am hearing.
