Do you use the new nct6775 driver ? Can you provide the complete output of the
sensors command ?

Could be, if the new BIOS changed the temperature sensor mappings, but I would
consider it unlikely. More likely you updated the driver; the new nct6775 driver
handles the various sensors on the chip differently.
The AUXTIN value suggests that either nothing is connected to the input pin, or
that the wrong sensor type (eg diode vs. thermistor) is selected. Most likely nothing
is connected to it. The mappings for temp6/7/8 are pretty common for Intel boards.

I'm using the w83627ehf driver in Fedora 17 (3.5.6-1.fc17.x86_64).
There does not appear to be any nct6775 module, so I assume that it's
either not in 3.5.6 or not built as part of Fedora's kernel.

Ok. The new driver is not upstream yet, so you would know if you use it.

Ok, then I guess it is more likely that the change was triggered by the BIOS
update. Interesting.

Attached is a config file for Intel DQ67SW boards with newer BIOSes.

# lm_sensors configuration for Intel DQ67SW (with newer BIOS)
#
# NOTES:
#
# Temperature input mappings were changed by a BIOS update
# between SWQ6710H.86A.0050.2011.0401.1409 (01-Apr-2011) and
# SWQ6710H.86A.0065.2012.0917.1519 (17-Sep-2012).
#
# Minimum and maximum values are the defaults from BIOS version
# SWQ6710H.86A.0065.2012.0917.1519 (17-Sep-2012).
#
# Intel Desktop Utilities 3.2.3.052 appears to get its default
# values from the BIOS.
#
# "FRONT" and "REAR" fan labels correspond to the motherboard
# headers, but not necessarily the actual fan locations.
#
# Minimum fan RPMs should be adjusted to reflect the behavior of
# the installed fans.
#
# "Memory DIMM Temperature" is presumably measured by a diode
# somewhere in the vicinity of the DIMM slots; "System Temperature
# might be a better name. If this is correct, 90 degrees seems
# like an extremely high threshhold for this reading.
#
# All hysteresis values are set to 75 degrees, which seems to be
# the default for the chip/driver.
