The first thing to do is to find which chipset you really have on your
motherboard. If the values really don't change, I believe to do *not*
really have a LM80. The output of "i2cdetect 0" and "i2cdump 0 0x2f"
would help. Reading your motherboard's manual would help a lot too.

BTW, which version of lm_sensors are you using?

Maybe you forgot to run "sensors -s". Still I think it won't help if
your chipset isn't a LM80.
