asus EC sensor and PCH temp.


New Member
hello, on a asus prime z270-a motherboard, the asus EC sensor gives one temperature reading, the PCH.
and there's another PCH temp reading under what's called "asus prime z270-a nuvoton ..."
they give 2 different temperatures. the EC sensor's temperature seems to be the correct one, the other one never really changes, almost always at 50c.

since the EC sensor comes with a warning, and potential system slowdown, i wonder if there's something can be done to calibrate the other PCH sensor to show the correct temperature?

The PCH temperature under the Nuvoton heading is not valid in this case and will be removed in the next version.
It should be safe to monitor the EC values, the warning is shown just in case of some potential issues that have been observed only on older systems.
