June 2, 201214 yr Well I found out where the documentation was for this unit: It's printed on the box, lol! (I stumbled upon it as I was putting the defective unit back in the box for RMA to Newegg.) I took a photo of it: http://www.flickr.com/photos/64687432@N05/7319348204/in/photostream I have read a lot of threads about people replacing the fans on these units because they were so loud; I wonder if they knew there were jumpers on the unit to cut the fan speed in half?--thereby decreasing the noise.
June 6, 201214 yr When I replaced my fans there were 5 jumpers if I remember correctly. Anyone know what the other 3 do (not J1 and J2)? I don't see the manual listed for download on Norco's site.
