Good fan to get for case that isn't too loud?

My old fan died but the new one I got is loud (despite the claims on the packing). I'm going to return it and am looking for suggestions? It's 120mm. Would be nice to have lights but not necessary.

For me, it's an easy choice: Noctua NF-A12x25. Very expensive but it has a good balance between air flow and noise (and it is pretty quiet). However, it doesn't have any LEDs.
