Well, I'm still trying to lower the noise level of that noisy rig that sits about 2 feet from my head while I'm at my desk. I've installed an Ultra-Quiet PSU, a nice, quiet cooler for the video card, and even added some acoustic foam. Each time I've added "silent" hardware, everything else sounds louder. Now I'm going to try to lose some decibels from the CPU cooler, with the ACC-L81, also known as the Cooler Master X Dream III CPU Cooler.
