Yes, you have to.

(which is the same once temp3 is ignored)

I believe you should ignore VCore 2 (i.e. in1).

This is a FAQ, there's a line to comment out in /etc/sensors.conf.

We have an alternate formula in /etc/sensors.conf for in5 and in6, you
could give them a try.

It does, and it is known to be true for the A7V8X-X. Motherboard
manufacturers are free to link whichever sensor input to whatever they
want (although we consider it a Bad Practice (TM)).
