The CPU core temperatures would be reported by another driver:
coretemp.
The temperatures reported by the ADT7490 are the temperature of that
chip itself (temp2) and the temperatures of 2 external thermal diodes
(temp1 and temp3). temp1 isn't connected on your system. As the ADT7490
is on your motherboard, temp2 is the motherboard temperature. temp3
could be anything on the motherboard: CPU, CPU socket, north bridge...
Thank you for such a quick and clear explanation.
As a starter, you can add the following to your configuration file:
chip "adt7490-i2c-*-2c"
label temp2 "M/B Temp"
Done.

OK. While you're here, you can add:
label in2 "+3.3V"
label in3 "+5V"
label in4 "+12V"
as they are pretty obvious, and:
ignore temp1
for clarity. Not sure which of in0 or in1 is your CPU core voltage...
Thanks...will do.
I don't know which kernel version is needed for the coretemp driver to
support the i7. Please share the contents of /proc/cpuinfo with us (the
first core is enough) and also let us know which kernel version you're
running.
linux> cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 30
model name : Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz
stepping : 5

OK. Your CPU is supported since kernel 2.6.32. But don't worry, just as
with the adt7475 driver, it is possible to build an updated driver
outside of the kernel tree. I've prepared it for you, you can download
the driver from:
http://khali.linux-fr.org/devel/misc/coretemp/
Fantastic! It works very well.
Thank you so much.
