Not quiet at all

I generally like Cooler Master products, but this fan does not live up to its descrition.
I have 2 Scythe Gentle Tyhoons, a Scythe Kaze Maru Slipstream2, and a BitFenix in my case along with this Cooler Master fan, and this fan is the loudest thing in the room. I can tell without any doubt which of my case fans are loud, and this oone is definitely it. Going to trade it out with a BitFenix 120mm fan soon.
Not too loud.

I have a few of these external to my case and even at 100% they are still fairly quiet. Every now and then you might get one that is a little louder, but I just let it run at 100% for a while and it seemed to get quiet like the rest.
