Sounds like either your cooler isn't mounted securly, your fans or pump aren't running properly. Shut it down go back over everything and make sure that things are where they're supposed to be. Usually it's something small that was overlooked while the excitement of building your Pc has you somewhat distracted. If that doesn't work report back
