Theoretically yes, but I am quite sure that it is PBKC
(Problem Between Keyboard And Chair ;-).

Try sensors -u for raw values. That should help us determine
the correct compute statements.

As far as I can see from the driver, in3 has an automatic
built-in scaling factor of 2 for this chip, meaning it already
reports twice the voltage you would expect for other inputs,
and thus should not need scaling in the first place.
In other words, sensors -u should already report
the correct value for in3.
