Hey Connor, I'd take the clip down and remove my name from it if I were you.
That click is pretty annoying, one of the tech-minded guys round here should know what it is but I'm guessing it's something to do with the HD parking mechanism.
Thanks for letting me know about that! I never would have remembered that itunes put my name on it. But I know it isn't the HD parking mechanism because if I just press around the trackpad on either the left or right side when it gets warm, it makes the sound. It even happens when I am not doing anything!
