I bought a new AMD XP based system in January and have been chipping away at the noise problem. First I swapped the heat sink that sounded more like a cheap hair dryer (Volcano 6) that came with my system for a Thermalright AX7 equipped with a Panaflow fan. Much quieter. But I was still surprised at the overall noise coming from my case. After unplugging the intake, exhaust, and power supply fans, I concluded that it was actually my hard drive that was causing most of the racket. I confirmed this by sending windows into "standby" mode which spools down the hard drives. The noise was not so much due to accessing, but just ambient whirring noise from the HD spinning.
The hard drive in question is a Maxtor 7200 RPM 40GB drive. I did some searching on this and other forums and read about the Seagate Barricuda drives. Most people said they were virtually silent. Someone I work with said he would buy my Maxtor, so I went out and picked up the Seagate yesterday. WOW - what a difference. When I first hooked it up, I was surprised when I was able to format it - I thought it was not working - it is that quiet. After reloading my OS and all my programs (what a pain) onto the new drive, I am so pleased. This change was at least as effective at bringing the noise levels down as the Heatsink.
