Solution
The Adaptive Thermal Monitor within the Intel CPU protects the CPU and the PXIe controller from thermal failure. This monitor adjusts the CPU's power consumption based on its temperature, ensuring the CPU operates below its maximum temperature.
If the CPU reaches TjMax, a throttling mechanism engages to prevent overheating. This mechanism reduces the voltages and frequencies of the IA and other subsystem agents in a gradual and coordinated manner, depending on the situation's dynamics. IA frequencies and voltages can be lowered to the Lowest Frequency Mode (LFM).
In the event of a catastrophic cooling failure, where the Adaptive Thermal Monitor cannot keep the CPU temperature below TjMax, a thermal trip event will be triggered to power down all the main rails of the PXIe controller.
