Many thanks for doing this.

Thanks! I have updated my sensors.conf at
http://www.eso.org/~llundin/sff/sensors.conf

For in[01256] I assumed that the reported value _is_ the voltage.
Is this a valid assumption?

The +12V is displayed in the BIOS, an example readout is 11.776V, see
http://www.eso.org/~llundin/sff/p1010501_800x600.jpg

Based on your comments it is now apparent that the voltages displayed in
the BIOS are reported by sensors in the exact same order. I guess I didn't
realize this because I didn't know that (some of) the voltages would
need scaling by sensors.

In one case `sensors` report in4 as 2.62V. If you have a suggestion for
how to determine the in4 scaling factor then I will be happy to help.

(I wonder if this could have the slightest relevance, but my board is
powered by a 200W PW-200-M from MINI-Box).

No, I did my last Windows installation around 2002. Although I would like
to help, I cannot say I am sorry about this.

Many thanks again for your interest, help and explanations,
-Lars Lundin.
PS. Is there any effort to have LM sensors detect an Nvidia GPU temperature?
I have a collection of (new and old) low-end Nvidia cards and would be
happy to help.
