Proposed config for gigabyte ga-g31m-es2l
--------------------------------------------------------------------
# lm_sensors configuration file for the Gigabyte GA G31-M ES2L motherboard, bios FH ,(rev. 2.x ?)
# compiled by cross referencing configurations
# MA770 DS3,GA-770TA-UD3 and as primary G33-DS3R
chip "it8718-*"
### Voltages
label in0 "Vcore"
label in1 "DDR18V" # "DDR18V" in BIOS
label in2 "+3.3V"
label in3 "+5V" # Not in BIOS
label in4 "in4" # Not in BIOS Misterious ?? 0.34v idle; 0.62v under load
ignore in5 # raw reads: +4.08 V
ignore in6 # raw reads: +4.08 V
label in7 "+12V"
# i think in8 should be ignored too ,verbatim from G33-DS3R
label in8 "Vbat" # Not in BIOS,raw reads +3.14 V as in7 ??
# verbatim from G33-DS3R.
# Vcore, DDR18V, +3.3V and Vbat are connected directly, so no compute
# line is needed for these. For +5V the chip is configured to use
# internal scaling. For +12V value from GA-770TA-UD3 is used
compute in3 @ * (6.8/10+1), @ / (6.8/10+1)
compute in7 @ * 3.963, @ / 3.963
# have no idea how to set voltages, may have been set by BIOS
# vid is not acurate at point of measuring as i've read on mailing list
# set in0_min vid * 0.95
# set in0_max vid * 1.05
set in1_min 1.8 * 0.95
set in1_max 1.8 * 1.05
set in2_min 3.3 * 0.95
set in2_max 3.3 * 1.05
set in3_min 5 * 0.95
set in3_max 5 * 1.05
set in7_min 12 * 0.95
set in7_max 12 * 1.05
### Temperatures
# only ONE sensor attached = low budget motherboard
label temp3 "CPU Temp"
ignore temp1 # raw reads -55C
ignore temp2 # raw reads -2C
compute temp3 @ +7, @ -7 # aproximation, i suspect bad sensor as on Charles' mobo
set temp3_low 10
set temp3_over 60
### Fans
label fan1 "CPU Fan"
label fan2 "Case Fan"
# fan1 has 4 pin connector for CPU heatsink
# fan2 has 3 pin standard
# Adjust for your own fans
set fan1_min 800
set fan2_min 2000

I really can not tell why is temperature reading temp3 = 26 deg. C.
Is it because of wolfdale core? Or bad sensor on motherboard?
Where is it connected , on-cpu-package thermal diode or other place ?
Trying to offset +7 deg. C , to approximate to BIOS readings.
About CPU fan...
In BIOS there is a feature called "smart fan"
and it does work - rpm is lower when temperatures are.
Only catch - it is configurable by using windows only utility,
it changes some ACPI settings , minimal treshold temperature or something similar.
in bios i've look up folowing information: (under health submenu)
--------------------------------------------------------------

...
Case opened Yes
Vcore 1.284 V
DDR18V 1.808 V

On the other hand,after more looking into it , inputs in4 and in7 might be different
in4 might be representing +12V using unusual scaling and
in7 might be +5VSB

Well, it seems , that under load in7 slightly drops from 12.46 to 12.36 to 12.30
,tested by running double glxgears which puts strain on cpu and graphics
and simultaneusly scaninng DVD disc which puts dvd device spinning.
(PSU is non-branded 450W which should have large drops of voltages,and makes it easier for this testings)
That would suggest in7 is +12V and in4 is something else
and i may have a clue what it is :)
There is an option on this motherboard , connected to overcolcking
called "FSB overvoltage controll".
It is placed in bios submenu "MB Intelligent Tweaker ,and by
means of elimination other two options "CPU voltage ctrl" and "DDR2 overvoltage ctrl"
is only one to remain. It is not shown in BIOS ,and i have not looked at EasyTune utilities.
So presumption is in4=FSB voltage.
as it reads in manual for this option:
---------
FSB overvoltage control
Allows you to set the Front Side Bus voltage
-- Normal Supplies the FSB voltage as required (default)
-- +0.1V ~ +0.3V Increases FSB voltage by 0.1V to 0.3V at 0.1V increment

In course of this testing i've discovered that my northbridge is quite hot
with or without graphics running .
On touch northbridge is hot , southbridge is milde ,and CPU is rather cold.
The same as noticed here in these threads
http://forums.anandtech.com/archive/index.php/t-276020.html
http://ubuntuforums.org/archive/index.php/t-1101041.html
Unfortunately motherboard does not seems to have sensor for northbridge :(
Will it be helpfull for northbridge if hsf on cpu is made to be running faster?
And earlier ticket about this series of mobo's was here
