Most important here is the kernel version, and the board brand and
model.

The IT8718F can monitor voltages up to 4 Volts directly, anything above
this limit requires scaling resistors, which must then be mentioned in
your configuration file so that "sensors" (or any libsensors-based
application) can compute the actual voltage. For example, try adding
the following to a new file under /etc/sensors.d:
chip "it8718-*"
compute in3 @ * (6.8/10+1), @ / (6.8/10+1)
This should make the +5V line look reasonable. The exact scaling factor
depends on your board.
Note that other voltage inputs may need scaling factors too, in
particular +12V (which I suspect is connected to in4.) See this article
for how you can figure out the voltage labels and scaling factors:
http://www.lm-sensors.org/wiki/VoltageLabelsAndScaling
in0 is most likely Vcore, in1 could be Vram if the system is using
DDR2, in2 would be +3.3V:
label in0 "Vcore"
label in1 "Vram"
label in2 "+3.3V"
But first check if we do not already have a configuration file for your
board...

in6 reads 4.08 V which is the maximum supported by the ADC. This means
the pin is not wired to a real voltage input, so it can be ignored.
This can be done by adding the following statement to your
configuration file (in the right chip section):
ignore in6
