NO . . . . . WAY
Dude
run as far as you can, call your mother, and hide under a table.
Nah I'm just kidding buddy!
It's fine. If you are really worried, take it to Best Buy or Gamestop and ask them for free. You can never be too safe.
If the sound is a gentle click from time to time, that should be fine, but if the clicking is continuous and noticeable, then I suggest that you call Nintendo.
I took mine back for doing that, i was worried it may have crapped up completely if it continued and got worse! However it was worse for me as it crashed when it did that.
