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

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

+12V             12.365 V
Current CPU temperature   35 C  ( slowly rised from 33 -- 34 -- 35 )
Current CPU FAN speed      1081 RPM
Current SYSTEM FAN speed   2311 RPM

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
