These events normally only happen due to failures of the thermal solution:
1. Verify the heatsink is properly attached and has thermal grease.
2. If the system has a heatsink 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).

5.2.4 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).
