UnderThreshold
A signed value that specifies the minimum temperature within the desired threshold, in degrees Celsius.
OverThresholdChangable
Indicates if OverThreshold can be changed by using IOCTL_STORAGE_SET_TEMPERATURE_THRESHOLD.
UnderThresholdChangable
Indicates if UnderThreshold can be changed by using IOCTL_STORAGE_SET_TEMPERATURE_THRESHOLD.
EventGenerated
Indicates if a notification will be generated when the current temperature crosses a threshold.
Reserved0
