Swapped out Fozzie’s Q-Max power supply that came with my case today in favor of a 400W silent power supply from CoolMax. It really is silent! This power supply actually came about 2 weeks ago, but the unit I recieved then was defective — whenever it was powered on, there was a very loud clanging noise that would come from the unit. This unit seems to work. Unfortunately I discovered that most of my computer’s noise does not come from the PSU in this case, but from the side case fan. I’ve never operated without it, so I am going to have a test run and see how the temperatures react to not having it. Fozzie is much quieter with that fan disconnected, especially combined with this silent power supply. The only sources of noise are the heatsink fan and the video card fan at the moment.
