Charlie,
Yes, I have battled the fan noise, too. I got replacement fans which
seemed a little quieter, but I still had no doubt when they were
running. I noticed that if I removed the fan panel from the rig and
held it in my hand while the fans were running, they were very quiet.
So I went to the local hardware store and found some neoprene (rubber)
washers about 1/16 inch thick. I placed them on the bolts between the
fans and the mounting plate. That has helped to quiet them down quite
a bit. I still know when they're running, but it's tolerable.
I've also found that where I place the K3 on my desk makes a
difference in how loud the fans sound. My desk is in a corner of the
room and if I place the K3 so the back is pointing into the corner,
the walls reflect any sound right back toward me and the fans are
louder. If I place it on a table in the middle of the room, I don't
notice the noise nearly as much.

to hear over the "whine" of the fans (or fan) even through
the padding on my headphones.
Has anyone tried to quiet them down with vibration
isolators, etc?
