Go ahead and call me crazy XD but I felt like ripping my Pegasus apart and swapping the fan for a more silent one It's not the standard fan connectors, but using the same fan type. 12VDC with signal for RPM. So i soldered the old connector to my new fan, works flawlessly. Exception: The utility now reports 700-800 RPM instead of 1000 so it's marked slightly orange now =D (the fan check) but I'm using WDC Green disks in it, so temperature won't be a problem, as it sits right next to my windows (and the cool air stream). The fan of the power supply still makes some noise but it has gotten better than before. Wanted to share this with you. Anybody else done something like that? I used a KAZE-JYU Slim fan by Scythe. 2000rpm, 100x100x12 The photograph of the fan is the original one. the one installed is my new one. EDIT: With all four drives now installed the fan is raised to 1000RPM and still remains more quiet than before. So no warning now All lights green pretty much.
