A temperature or voltage sensor reached a critical threshold.
A sensor monitored a temperature or voltage in the critical range. When the problem is resolved, event 47 is
logged for the component that logged event 524.
If the event refers to a disk sensor, disk behavior may be unpredictable in this temperature range.
Check the event log to determine if more than one disk has reported this event.
