The Necrons won't destroy the nids. The nids avoid them like the plauge (which would be a good method of killing them, if an adaptable enough one is found) and they could destroy chaos, or at least put a sizable dent in it. What do the necrons want? TO DESTROY THE WARP. The necrons get a huge amount of help in this regard from the nids, if they weren't behind the nids in the first place.
