SMBUSMASTER 0 is the CPU, so we have a match with the temperatures.

Both Vcore and Icore should be much less when idle, and higher under
load. The data from the Super-IO chip suggests that it is a Nuvoton
chip. Can you report its first voltage (in0) ? That should roughly
match Vcore.

It should be much lower when idle, actually, not higher.

All other data looks ok.
