 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.
