/dev/sensors/temperature/pch/*

The pchtemp driver provides the system the ability to read the digital temperature sensor found on several Intel platform controller hub (PCH) chipsets. The following chipsets are supported which cover most Intel Core family (non-Atom) CPUs starting with the Haswell generation:

Temperature information is available to the system via the fault management architecture (FMA). The file system location and programming interface to the pchtemp driver are considered , subject to change without notice, and should not be used directly. Raw temperature information can be dumped through the FMA developer utility .
