i2cdump is no longer part of lm-sensors and is now part of a separate
package named i2c-tools. Please install that package first and then you
should have i2cdump. When you have it, please run the isadump command
as well, it's better to have both dumps done at the same time for
comparison purposes.

Could be that temp1 isn't wired at all. Does it change in a consistent
way depending in the system load? I suspect that temp2 is the CPU
temperature and temp3 is the system temperature on your system. This
would lead to the following configuration section:

   label  temp2  "CPU Temp"
   label  temp3  "Sys Temp"

   set temp2_max      62
   set temp2_max_hyst 58
   set temp3_max      45
   set temp3_max_hyst 42

And if you can't make sense of temp1, you can add:

   ignore temp1

Is the BIOS displaying it? How many wires does this fan have?

Remember that the default labels in sensors3.conf may not match your
motherboard.

Also, the w83627ehf driver is adjusting the fan clock divisors
automatically, so it may take a couple runs of "sensors" before fan
speeds show.

OK. When I received your dumps, I'll fix sensors-detect so that it
handles this case properly and no longer suggest the lm78 driver. I'll
also update fix the lm78 driver so that it refuses to attach to
W83627EHF and DHG chips.
