So it works as expected.

This is expected. "set" lines are only used when they are there.
"Missing" lines simply have no effect with "sensors -s", they are not
magically replaced by any kind of default.

The first test proves that the values are read and written properly, so
the only problem here is the default value, which is either set by your
BIOS or not set at all. There's not much lm_sensors could have done bad.

Can you check in sensors.conf if you explicitely set the fan clock
dividers to 8? I think that the default is 2. Maybe the divider change
affected the min value in an unexpected way.

Also, you said that previous versions of lm_sensors would yield a
different default min value. What was that value? What was the value of
the dividers?

No problem. I just checked and can't see the problem you report on my
system. However it might not be relevant since my via686a chip is *not*
connected on my motherboard.
