Voltages aren't "wrong". Vccp and +3.3V are correct (labelled Vcore and
AVCC/VCC, respectively). The other inputs simply need scaling factors
and labels. These are specific to each board.

Fan speeds are all 0. How could this be OK?

You should ask Intel for the voltage input pin mapping and scaling
factors.

Failing that, if you are able to gather several samples of each of 12V,
5V and 5Vstby in the BIOS, we can guess the scaling factors from the
sample differences, and from that, find the pin mapping.
