Probably +12V

and +5V. If your system uses DDR2 SDRAM, in4 could be Vdimm. in5 could
be Vagp. If I'm right, you can add the following lines to the
w83627dhg-* section in /etc/sensors3.conf:

   label  in1  "+12V"
   label  in4  "Vdimm"
   label  in5  "Vagp"
   label  in6  "+5V"

To get rid of the alarms, uncomment the "set in*" statements, adjust
the limits as needed (typically -10% and +10% of the nominal value),
and run "sensors -s".

I guess that you have only 2 fans in this system, so you can add:

   ignore fan1
   ignore fan4
   ignore fan5

And change fan3's label:

   label  fan3  "Case Fan"

These are very reasonable fan speeds and I have to admit that I am
surprised the one the fans "sounds like your vacuum cleaner".

While temp1 and temp3 look reasonable, temp2 is way too low to be
correct. What does the BIOS display? Maybe you need to add some
arbitrary offset.
