These events normally only happens due to failures of the thermal solution:
1. Verify heat sink is properly attached and has thermal grease.
2. If system has a heat sink fan, ensure the fan is spinning.
3. Check all system fans are operating properly.
4. Check that the air used to cool the system is within limits (typically 35°C).

Discrete Thermal Sensors
Discrete thermal sensors do not report a temperature at all
– instead they report an overheating event of some kind. Examples as VRD Hot
(voltage regulator is overheating) or processor Thermal Trip (the processor got so hot that its over-temperature protection was triggered and
the system was shut down to prevent damage).
