I should have known that Murphy's Law would kick in on this one. I
shipped this machine off to a remote location yesterday. When it
arrives, I will try to look into this. Sorry for any inconveniences.

If needed, I get get remote hands to verify.

No problem, I'm busy with other stuff anyway and won't have time to
look into clean IT8726F support anytime soon.

Fans and temperatures look good, voltages not quite so. Not really
surprising, as voltages are the only significant difference between the
IT8716F and the IT8726F as far as hardware monitoring is concerned. The
difference is that the in4, in5 and in6 pins can be used for an
alternative function. The datasheet isn't very clear what this
alternative function is though. I asked my contact at ITE and he tried
to clarify, he did help to some degree but I have to admit I am still
confused. So I think we'll have to wait for more users with that chip
to find out how the IT8726F works exactly.
In the mean time, at least Vcore, VDDR, 5VSB and Battery look OK for
you, so not too bad.

^^
This is the register which is supposed to make a difference, but bit 6
being set probably means that your chip behaves like an IT8716F would.

Well the idea is to compare the values displayed by the BIOS and the
values displayed by "sensors" to ensure that the labels match and the
compute forumlas are correct. But the items you list here are probably
already correct so maybe you don't want to bother.
What would have been really interesting are the other values - +3.3V,
+5V, +12V, which aren't correct in the sensors output. But if your BIOS
doesn't show these, there's no possible comparison and it might even
mean that these pins aren't wired. If some of the voltage values
displayed by sensors change all the time, we can assume the pins are
left floating.
Quoting myself:

You didn't report what was to be seen in the logs.

I will see what I can do about getting a comparison to the BIOS output.
I pasted in the one line from kern.log. Was that what you were
looking for, or something else?

Ah sorry, I totally missed it. This is what I was after. Sometimes we
are able to guess some voltage labels from the devices configuration,
and that shows in the logs, but this doesn't appear to be your case, so
no luck.
