here's the scoop- I have an MSI K8MM-V mobo with a 1600MHz AMD Sempron processor and an nVidia GeForce 4000mx and 2 SATA HDDs. I have not modded or upgraded anything. The computer is running very loud. It is almost unbearable sitting up on the desk. I believe that it is the CPU fan that is causing the noise. It's a stock fan, so I know it's crap. I found this fan on Newegg and it looks pretty sweet. I don't want to get it if it won't make my system any quieter. I don't know how to check on temp and stuff, but so far there haven't been any problems. Is there a way to quiet the beast without a new fan? otherwise, is that fan a good option?
