Yap PCH Temperature shows 0, i updated with the hope of fixing Intel ME disappearing Issue the 0.0.0.0 in bios information,
BIOS 0037 does not fix Intel ME 0.0.0.0 issue in fact now they are two issues in 0037 PCH Shows 0, and Intel ME Shows 0.0.0.0.
Temporary fix is to restart machine till the Intel ME shows correct version, and when Intel ME shows then the PCH shows correct temp reading (tested method)
@shomaru which processor are you using?
Check your Intel ME if it's showing correct version or it appears 0.0.0.0
So if the PCH Issue is fixed the Intel ME issue will be fixed too.
