The configured source for each of the +temperature sensors is reported in tempX_label. + Temperatures are measured in degrees Celsius and measurement resolution is 1 -degC for temp1 and 0.5 degC for temp2 and temp3.

Fan rotation speeds are reported in RPM (rotations per minute). An alarm is triggered if the rotation speed has dropped below a programmable limit.
