Can you please report what the problem was? I would like to fix it.

If you want help to figure out the labels and scaling factors of the
remaining voltage inputs, please go to your BIOS, find the hardware
monitoring menu, and write down all voltage values it reports. If a
given item oscillates between different values, write them all down.

Are these correct?

Apparently temp2 isn't connected so you can add:

   ignore temp2

to your configuration file. You could also adjust the temperature
limits for temp1 and temp3.

If you come up with a good configuration file, please post it and I'll
add it to the wiki.

Unfortunately I can't read Russian.
