Averaging 3,200kh/s with 2 Fury's.  382 Clock, 300 Read Count.  Using current Darkwinde build.  31 hrs running.

I haven't tried different RC settings yet.

60 watts per Fury after putting all of the four fans on a separate power supply.  I had an old fan controller that lets me control RPM to cut down the noise.  One of the extra fans I'm using is a Delta that is (was) very loud.
