If you use the full curses based interface with Avalons you will get this
information:
AVA 0: 22/ 46C 60%/2400R
AVA 0: 22/ 46C 2400R
The values are:
ambient temp / highest device temp set fan % / lowest detected fan RPM.
ambient temp / highest device temp lowest detected ASIC cooling fan RPM.
Use the API for more detailed information than this.
