This seems to match the output of "sensors" except for the missing
thermal margin value. It certainly comes from the PECI input, for which
we have no support.

The above output suggests that temp1 isn't used on your system, temp2 is
internal to the ADT7490 so it would be the motherboard temperature,
while temp3 would likely be the CPU temperature. Does the BIOS report
more than 2 temperature values?
Yes but the top one is the thermal margin, so you are correct, the first
temperature for this board needs to be disabled so lm-sensors does not look
for it, see: intel-p55kg-system-setup-realtime-hardware-monitoring.jpg

This isn't the driver's job, as it can't tell the difference between a
permanently unused input and an actual sensor breakage. If you want to
hide temp1, just add the following to your sensors3.conf's adt7475
section:

   ignore temp1

As for the thermal margin, we lack support for this in libsensors at
the moment. How this could be implemented is still under discussion.
Until it settles, I can't add support to the adt7475 driver.

Thanks,

I added the ignore temp1 and also tried your latest release:

adt7490-i2c-0-2c
Adapter: SMBus I801 adapter at 7000
in0: +1.52 V (min = +0.00 V, max = +3.31 V) Vcore: +1.26 V (min = +0.00 V, max = +2.99 V) +3.3V: +3.31 V (min = +0.00 V, max = +4.39 V) +5V: +5.11 V (min = +0.00 V, max = +6.68 V) +12V: +12.00 V (min = +0.00 V, max = +15.69 V) in5: +2.22 V (min = +0.00 V, max = +4.48 V) fan1: 1345 RPM (min = 0 RPM)
fan2:       1308 RPM  (min =    0 RPM)
fan3:        729 RPM  (min =    0 RPM)
fan4:        933 RPM  (min =    0 RPM)
M/B Temp:    +41.8°C  (low  = -127.0°C, high = +127.0°C)
(crit = +65.0°C, hyst = +61.0°C) temp3: +45.2°C (low = -127.0°C, high = +127.0°C)
                      (crit = +65.0°C, hyst = +61.0°C)

Looks good, thanks.

Justin.
