FAQ 4.1.1
"Q: Fans sometimes/always read 0!!
(...)
A: You may need to increase the 'fan divisor'. See doc/fan-divisors in
our package for further information."
In other words, adding:
set fan2_div 4
set fan3_div 4
to the it8712-* section of your /etc/sensors.conf file should solve the
problem.
> M/B Temp and CPU Temp are reversed.
>From the default sensors.conf, it8712-* section:
"
# The A7V8X-X has temperatures inverted, and needs a conversion for
# CPU temp. Thanks to Preben Randhol for the formula.
# label temp1 "CPU Temp"
# label temp2 "M/B Temp"
# compute temp1 (-15.096+1.4893*@), (@+15.096)/1.4893
"
The compute line may or may not work for you, BTW.

And can easily be tinkered with:

If VID works for you, comment out "ignore vid" and use:
set in0_min vid*0.95
set in0_max vid*1.05
If VID isn't correct, hardcode the nominal Vcore value for you CPU:
set in0_min 1.75*0.95
set in0_max 1.75*1.05
> VCore 2: +0.00 V (min = +2.40 V, max = +2.61 V) ALARM
Seems to be wired to ground, so you would comment out these lines:
# set in1_min 2.4
# set in1_max 2.6
and add:
ignore in1
> +3.3V: +6.72 V (min = +3.14 V, max = +3.46 V) ALARM
>From the default sensors.conf, it8712-* section:
"
# If 3.3V reads 2X too high (Soyo Dragon and Asus A7V8X-X, for example),
# comment out following line.
compute in2 2*@ , @/2
"
So just comment out this compute line. (I think it should be the default
BTW.)

These ones are OK.

Most probably not connected, as per FAQ 4.6.1:
"Q: -5V and -12V readings are way out of range!
A: It's very frequent that negative voltage lines are not wired because
motherboard manufacturers don't think they're worth monitoring (they
are mostly unused these days). You can just add ignore inN lines to
/etc/sensors.conf to hide them."
Additionally, I'd invite you to comment out set in{5,6}_(min,max} lines
so as to prevent irrelevant alarms and speed up "sensors -s".
> Stdby: +4.89 V (min = +4.74 V, max = +5.24 V)
This one is OK.
> VBat: +4.08 V
Overflow here, no idea what Asus made with this one.

You should find it at:
Hardware sensors support > Other I2C devices > EEprom (DIMM) reader
But this is unrelated with your sensors readings, which will be improved
only by tweaking the it7812-* section of /etc/sensors.conf as described
earlier.
