Looks like temp4 is not connected.

In manual, (intel usually creates a technical document about MB and there is
written where sensors are)
I just checked and it is not there... But they may used what was recommended by
temp5-temp6 are thermistors placed somewhere on the board. (Is 16C likely?)
temp1-temp4 could be disabled, monitored through PECI or analog - thermal diode.
Please go to:
It will show the actual type. You could also RTFM in
Please provide the output so we know what is what
This reminds me... This would be great case for the tempX_label file, so it will
show the string "None" "Thermal diode" "PECI" ...
Do you like that idea?
