I bought 2 of these to replace the fans that came in my case. I am very happy with these so far. They are very quiet and move plenty of air.My case temp hit about 40c tops with the fans set at the lowest speed setting in the BIOS.I have 2 Radeon 4770 cards running in crossfire mode, as well as having my system overclocked.

Recently the 360 in our entertainment center over heated. The door was open but the building heat in the area was enough to shut down the system with 2 red rings. I bought this and wired it to an old router power converter. That is plugged into my reciever and when you turn it on the fan comes up. The fan is screwed to the back of the entertainment center that I cut a hole in. This one fan is more than enough to cool the receiver, 360, wii, ps3, and cable box. Not that all of them are running at once but it works great. It even gives a blue glow from behind everything that looks better than I thought it would. This fan isn't as bright as most with clear holders surrounding the blades. Great fan over all. Runs very quiet and moves a ton of air.

When you buy a cooler master product you know you can't go wrong. I bought one of the 120mm green led fans plus one with red leds and another one with blue leds. They work like a charm. Quiet and reliable. I'm very happy with them and I'd recommend them to anyone.
