_ART is the AML method for "Active Cooling Relationship Table".
iIt tells the system how fans are related to temperature sensors.

It is likely that Windows uses DPTF on this platform, and since DPTF
is not using _ART, Linux may be pointing out a vestigial _ART.

Anyway, if your system doesn't handle being hot very well -- this error
message is related to that capability.
