Preliminary question, did you run "sensors -s"?

> VCore 1:   +1.55 V  (min =  +1.42 V, max =  +1.56 V)
> VCore 2:   +1.66 V  (min =  +2.40 V, max =  +2.60 V)   ALARM

You may have to adjust the min and max values in /etc/sensors.conf (look
for the it87-* section). The nominal value for VCore 1 & 2 depends on
the CPU and we can't guess it. We use 1.5V and 2.5V because these are
the most frequently seen values, but if your CPU uses different
voltages, you have to adjust the configuration file to match them. VCore
1 seems to be OK here, but VCore 2 isn't, for sure.

> +3.3V:     +6.04 V  (min =  +3.12 V, max =  +3.44 V)   ALARM

This is a known problem, and the fix is detailed in the config file. You
may still have some problems after using the fix however.

> +5V:       +4.99 V  (min =  +4.72 V, max =  +5.24 V)
> VBat:      +3.23 V

At least these ones are prefect :)

> -12V:     -27.36 V  (min = -12.63 V, max = -11.41 V)   ALARM
> -5V:      -13.64 V  (min =  -5.28 V, max =  -4.81 V)   ALARM

There are alternate furmulae in the config file, please give them a try
(don't forget to run "sensors -s" afterwards).

> +12V:      +0.00 V  (min = +11.36 V, max = +12.60 V)   ALARM
> Stdby:     +0.00 V  (min =  +4.72 V, max =  +5.24 V)   ALARM

I'm really astonished (especially by the +12V). Do you have readings for
these ones in your BIOS setup screen or other OS?

This reminds me of something I read about the ADM1025/NE1619, but I'd
need to read the datasheet for your chipset to confirm. Do you know
which of the IT8705F, IT8712F or SiS950 you do actually have?

> fan1:     2732 RPM  (min =    0 RPM, div = 2)
> fan2:        0 RPM  (min = 3000 RPM, div = 2)          ALARM
> fan3:        0 RPM  (min = 3000 RPM, div = 2)          ALARM

I guess you simply have only one fan. Add "ignore fan2" and "ignore
fan3" lines to your config file (section it87-* of course).

> Temp1/MB:    +75°C  (min =  +20°C, max =  +40°C)
> Temp2/CPU:   +86°C  (min =  +25°C, max =  +45°C)
> Temp3:      +127°C  (min =  +25°C, max =  +45°C)

I admit the readings are probably wrong. Try using the temp_type
parameter (for more details, read doc/chips/it87), maybe it'll help.
