Looking at your numbers I would say that it is most likely that
several of these readings are not the correct values. They are either
not scaled correctly or the sensor is not the one used by the
motherboard so the values are meaningless. At times I have gone to the
motherboard's (TYAN) page and downloaded a correct lmsensors.conf file
that matched my motherboard and thus I could trust the output.
