Had that happen once with a scythe style fan.....stupid molex connector managed to get in there and a blade just snapped right off. Popped off a blade on the opposite side of the one that broke to help balance it a little. Didn't completely kill the roar, but it dropped it enough to be tolerable until I could replace it.

Was perfect timing too, the stock intake fan burned out just as my new fans arrived. Fortunately I had ordered a 5 pack of Kaze Jyuni's for the discount...man those things can move some air. Have a bit more roar than I like (system sounds like it's gearing up for take off), but I can actually feel the air getting sucked in the front.
