Many Dell notebooks made after ~2020 support a WMI-based interface for
-retrieving various system data like battery temperature, ePPID, diagostic data

and fan/thermal sensor data.
This interface is likely used by the `Dell Data Vault` software on Windows,

flow with other ACPI methods (_BIX or _BIF for battery related methods
for example).

related methods (sometimes overwriting static ACPI data fields can be used
to test different sensor type values, since on some machines this data is
not reinitialized upon a warm reset).
