This should be easy enough to verify. You can temporarily unplug any
system fan (or slow it down by pressing your finger on the middle part -
don't get hurt), and see which reported speed drops.

Most certainly in0. in7 is 3VSB (Stand-By 3.3V) and in8 is Vbat
(battery). It's quite rare that BIOS reports these.

Easy enough to add once you are certain your configuration is OK.

No 4th fan header, or just unused on your system? You should only
ignore a fan when the header isn't there.

The following labels, taken from sensors.conf.default, are clearer:

    label in7 "3VSB"
    label in8 "Vbat"

This would be quite surprising. On recent CPUs, Vcore is always lower
than the ADC's resolution, so it shouldn't need any scaling. How did
you come with this value?

When sending such configuration files, it is a good practice to also
include the output of "sensors -c /dev/null", so that we can review
your choices and possibly help you improve your configuration file.
