Sorry I do not have an anwer for you, but do have a couple clues.
Here is a link to someone else's solution for a different gigabyte
motherboard that has offset of -15C for the temperature readings.
http://www.lm-sensors.org/ticket/2139 - It includes the details of how
they edited /etc/sensors.conf
You probably have to do something similar. Since you get a reading
from the bios your should be able to alter sensors.conf and run
sensors -s until you get a reading that is close to what the bios
says. Found this on the lm-sensors site that may also apply to your

My system is the same, that dir is empty. I found a little perl
program on http://khali.linux-fr.org/devel/lm-sensors/ that didn't
work on my system, but provided a clue. That program attempted to
read a directory that also didn't exiost on my system
(/sys/class/hwmon/hwmon1/device), I found a similar directory, but it
didn't have files that matched the names in the program.
I did find that on my system (F7) there is a directory
(/sys/class/hwmon/hwmon0/device) that has a couple files called
temp1_input and temp2_input. I wrote a perl program to read those
files every five seconds and print the results. The values track
perfectly with the output of the gnome sensors applet. Well, the
values are 1000 X the celsius temperature, but the values divided by
1000 exactly match the temp shown by the applet.
