Good.

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
Winbond

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:

cd /sys/class/hwmon/hwmon0/device
cat name
cat temp?_type

It will show the actual type. You could also RTFM in
kernel/Documentation/hwmon/w83793 ;)))

Please provide the output so we know what is what

Jean,

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?

Rudolf
