Here's what I have. http://www.newegg.com/Product/Product.asp?...N82E16811999344 I have two of these in my case. One intake and one exhaust.. The original fans I bought with my case, just could not keep up with my cooling requirements. They were quiet, but having a couple of 8800gtx running in SLI need air, not silence. As long as the noise doesn't bother you, they will move a lot of air. Then again, they have a speed control on them. So you are able to slow them to 800 rpms if you wish.
