Well, the PSU I got came with a fan speed controller. All of my fans run on molexes, and that's what it supports, so I plugged them all up to that and turned it all the way down (it doesn't decrease the flow that much, trust me, and I'm keeping a sharp eye on temperatures; right now I'm running 32 Celsius CPU, 32 Celsius System, and 27 Celsius on my main HDD). Bam! The noise level dropped a whole lot. Now, the loudest thing I can hear is my CPU fan, and that is quiet. Thanks for your help, anyway!
