Hi Justin,
Thanks for the fast test and report. Looks overall OK. Do you actually
have 4 fans in this system?
I have 8 or so fans in the system with at least two-three connected via the
on-board fan connectors.
Why does temp1 say fault?
The driver merely reports what the chip says. According to the dump you
sent on October 16th, register 0x25 has value 0x80, bits [3:2] of
register 0x76 have value 11b, this is a temperature value of -127.25°C.
The fault is confirmed by bit 4 of register 0x41 (1b) and bit 6 of
register 0x42 (1b) which stand for temp1 out of limits and temp1 open
or short circuit, respectively.
All of the temps in the BIOS report properly.
Can you please copy all the information reported by the BIOS and send
it over? It will be interesting to compare what the BIOS says with what
the adt7475 driver reports.
Here is a screenshot of nearly every screen in the BIOS:

The one that shows the temperatures and fan speeds is labeled:

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
I think we can use the following as the default configuration for the
ADT7490:
chip "adt7490-*"
label in1 "Vcore"
label in2 "+3.3V"
label in3 "+5V"
label in4 "+12V"
set in2_min 3.3 * 0.90
set in2_max 3.3 * 1.10
set in3_min 5.0 * 0.90
set in3_max 5.0 * 1.10
set in4_min 12.0 * 0.90
set in4_max 12.0 * 1.10
label temp2 "M/B Temp"
Please let me know if you need anything else, thanks.
Justin.
