Any Quad experts in here? I picked one up at an auction recently but the fans seem on the loud side whereas I thought they are meant to be very quiet machines. It doesn't seem to get louder if I remove the transparent air deflector, do they normally with Quads, or does this mean the fans are constantly running faster than they should? (my air-cooled dual G5 is extremely loud if you remove the deflector but very quiet if it is in place, whereas this Quad is somewhere in the middle) I tried running ASD 2.6.3 to calibrate it, but it ran for 4 hours not changing from "starting calibration of CPU 0" and appearing to be frozen (mouse not moving etc) before I had to turn it off (ASD says calibration should take 10 to 30 minutes). The Overtemp and Checkstop (I think) red lights inside come on pretty much as soon as the calibration is started, not sure if that is normal or not? Other wise the machine boots up and runs fine as far as I can tell, it's just louder than it should be, so am trying to work out if there is something wrong with it or not!
