I just checked (left the rig so I could access it remotely with VNC) and it is 35% or less on the CPU running Fldigi, but not much to decode right now. With WSJT-X it sits at around 10% and jumps to 40% max when decoding the many signals on the band. With the new case it is staying nice and cool and working well and has been on about 24hrs right now.
