I have been playing with the values and I feel that I have made some
progress. Identifying the sensors is difficult as they all seem to show
different patterns.
Under it87, temp1 is almost constant, it hovers around 26C, currently
it's at 24C and I've seen it go as high as 27C. Using stress (with all
the different hogs), the temperature does climb, but not right away and
this leads me to believe that this is indeed a sensor and it monitors
the ambient/case temperature.
temp2 is a negative value and stays constant within a 3 degree range if
set to a thermal diode, if set to thermistor it seems to stay constant
at negative 55. This is all throughout multiple stress runs, both
memory, i/o, disk and CPU. I'm assuming that this sensor is not connected.
temp3 swings wildly from -110 to about 108 degrees, and all over in
between. I've tried setting it as a thermistor or diode, and it still
goes all over the place. I'm wondering what I can do with this sensor
as it's not really reading correctly. It must be sensing something, as
it does produce values all over the range, I'm just stumped as to what
kind of compute function I would need to use to make this thing make any
kind of sense.
I will further ask questions about the rest of the detected chips as I
get to them, though I'd appreciate any thoughts on the above temperature
sensors.
Thanks!

OK, I give, what is the LM90 chip usually used for? I understand that
temp1 is its own temperature. Though is that basically the only use of
an lm90 chip? To test one local and one remote temperature?
What have people used in real world examples for this chip? Usually M/B
temp and CPU temp? I see that temp2 jumps with the CPU temperature, I'm
going to assume it's correct as it matches the BIOS readings and I will
label it as such.
Though the k8 temps measure each core. And... They're off by a few
degrees (12C in the above example) so which should I take as correct?
None of the above examples have compute lines so they seem to be as raw
as lm-sensors believes them to be.

Well, yes, that's a temperature monitoring chip, what else would you
want it to be used for?

Yes, temp1 = M/B temperature and temp2 = CPU temperature is the most
typical usage for LM90-like chips on mainboards. On graphics cards,
they are used as temp1 = card temperature and temp2 = GPU temperature.

The K8 internal sensors have not impressed us by their reliability so
far. See the note on http://www.lm-sensors.org/wiki/Devices and various
reports on this list.
The LM90 temp1 reading should be accurate out of the box, no compute
statement needed. The LM90 temp2 reading might need an offset,
depending on the thermal diode model being used. Ideally, the BIOS
would have set it up properly, so that it itself reports accurate
temperature readings. I agree that the LM90 temp2 value is quite high
on your system, but I would tend to trust it, especially if the BIOS
reports the same.

This would be an IT8705F chip, not IT8712F as you wrote above.

If it jumps all over the place no matter the setting, then you can
safely conclude that it is left floating and should be disabled/ignored.

Given that the board vendor used a dedicated LM90 temperature
monitoring chip to track the CPU temperature, I wouldn't be surprised
if most or all of the IT8705F temperatures inputs were left unused. The
it87 driver forcibly enables temperature monitoring channels if they
are found all disabled when the driver is loaded. It probably shouldn't
do that, especially given that each channel can be configured in two
different modes (thermistor and thermal diode) and the driver has no
way to know which mode would be correct. Incidentally, your modes
configuration for temp1, temp2 and temp3 matches the arbitrary default
set by the it87 driver, so it is possible that all sensors were indeed
disabled originally.
I will fix the it87 driver later today to no longer arbitrarily enable
temperature sensors. This should clear some confusion as least on some
boards.
What temperatures are reported by the BIOS on this machine? This would
be a valuable hint.

I visited your site and found a few examples that said the manufacturer
left the sensor floating. I was unaware as to what that meant exactly.
Thanks for letting me know. I have now disabled all three temperature
readings.

The BIOS reports that CPU temp is at 60C and that SYS temp is at 20C.
I've run across a few posts about the CPU temperature reported via the
windows utility and the bios reports as being off. I know the
manufacturer released a BIOS revision after mine, though unfortunately
it's quite buggy and most of the people who ran/run this board
downgraded back to the version I'm running.
I've guessed at the second temperature that the LM90 reports and used a
calculate formula to reduce the reading by 10% as 60C is very high for
an undervolted Opteron 165.

Oh nothing specific, I was only unclear of its function as I had an
ITE8705 _and_ an LM90 which seemed superfluous hence my question as to
its purpose.

I can't connect to the lm-sensors.org site, it keeps timing out for the
last few hours. I will attempt at reading the wiki entry later. Should
I start looking for an offset to garner a better reading from the k8
sensors?

As in my other post to you, it's not exactly accurate, the manufacturer
attempted a fix and broke the rest of the BIOS. I'm guessing with a
compute line to reduce the reading by 10%.
