Yeah, free stuff can suck

I tried plugging both in at the same time, and the total of 4 fans could be heard from 30 feet away and around a corner. It was a good thing I don't need 48 ports
David, that would be a good idea, but I think I'd kinda like to hang on to them for now. They're good switches, and if I ever need something like this in the future, I've got it.
I suppose if I can't get the thing open to work on it, it will be okay. The switch resides in a closet in my bathroom, and with that door and another door closed, I can't hear it at all.
I suppose I could also permanently stick something in the side to jam one of the fans
