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)
--------------------------------------------------------------

Reset  Case open Status [Disabled]
...
Case opened           Yes
Vcore             1.284 V
DDR18V            1.808 V
+3.3V             3.344 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
...
CPU WARNING temperature  [70 C / 158 F]
CPU FAN fail warning     [Disabled]
System FAN fail warning  [Disabled]
CPU Smart FAN controll   [Enabled]
