Well I don't think they aren't 'wrong' but they do need scaling :-)
(although the negative ones are strange), see the example sensors.conf
(http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/etc/sensors.conf.eg)
for how to do so, specifically the compute lines. You will need to
have some idea of what they normally should be, and if your bios gives
you the same info you can compare with that. Also try ipmitool and see
what it reads, it will probably give you the same thing though.
