I finally had time to look into the open hardware monitor code.
The answer is quite simple - the board get the CPU temperature using PECI,
which the w83627ehf/nct67765 driver reports is as "PECI Agent 0".
Open Hardware Monitor maps that temperature into the CPU temperature display
and ignores CPUTIN. Which makes sense, since the purpose of PECI is to report
the CPU temperature.
So all you need to do is to ignore the value of CPUTIN and use the "PECI Agent 0"
