Hello list, this is my first time posting here, and I come with some
questions about my server motherboard with the hopes that I configure
sensors on it correctly.
While this Soltek board is relatively old (as the company is no longer
in business), I had never used it since the day that I bought it. The
board was recently installed into a server role and I hope to monitor
its health from a distance.
While sensors detects the correct chips installed on the board, the
values are useless.
I'm wondering if anyone can shed light on how to set the values
correctly for this board. Here's some pertinent info:

temp2: -86.0°C (low = -1.0°C, high = +127.0°C) sensor =
thermal diode
temp3: +14.0°C (low = -1.0°C, high = +127.0°C) sensor =

temp2: +63.1°C (low = +0.0°C, high = +70.0°C)
(crit = +85.0°C, hyst = +75.0°C)
If I can provide more information, let me know.
OK, I give, what is the LM90 chip usually used for?
Monitoring temperature.
I understand that temp1 is its own temperature.
Yes it is.
Though is that basically the only use of an lm90 chip? To test one
local and one remote temperature?
Well, yes, that's a temperature monitoring chip, what else would you
want it to be used for?
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.
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.
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.
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.
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.
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?
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.
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%.
