Hi Jean,

unfortunately, I cannot do that: the motherboard is build into a
root-server I rented and is located in a remote location I have no
physical access to. I can ask for access to its monitor and keyboard via
a remote KVM solution in order to access the BIOS information, but that
is about the end of it. The server operator charges per 15min of "remote
hands", and I am to stingy to ask them to swap the fan connection.

Thanks for the info. I have updated my configuration file accordingly.

If you mean the thresholds: how does one decide on which values are
max/min, or critical?

I checked the manual: there is a "System 3" Fan, but it does not seem to
have a Sensor connector (the pin is labeled "No Use" in the manual and
the BIOS does not report it).

I ran several comparisons between readouts from the BIOS and running
sensors with a dummy configuration. Then I tweaked the compute values to
match as well as possible the BIOS values. I read in the BIOS (some
values were quite noisy):

CPU Vcore           1.224V
3.3V                3.376V
5V                  4.961V
12V                12.144V

Vcore was very stable, so I tuned compute1 to match it. For compute5, I
did the same (even though the values varied slightly). I cannot
remember, whether I did the same to compute4 or stayed with the default.

Sure (the long "sensor = ..." lines get folded by my MUA):

Any further suggestions on how to tweak the warning levels for all the
settings?
