That's a heat sensor. It just screws into the head but not into the cooling system. Atleast that's the way it is on the PI heads. I can't image it being any different on the NPIs. I'd take it out and look in the hole just to be sure. In fact, there should be the same hole on the other head (that one will be towards the back) and won't have anything in it.
