CPU Cooling Fan and Heatsink Assembly
This assembly is the primary thermal management component; failure occurs when the internal liquid in the heat pipes loses vacuum or the blower fan bearings increase rotational friction. Replacing the entire module addresses both the mechanical airflow failure and ensures a fresh seal between the processor and the heat-exchange surface. This is the standard fix for laptops where thin-form-factor constraints lead to heat-soak and emergency power-off sequences.

High-Performance Thermal Interface Material
Over cycles of thermal expansion and contraction, the factory-applied paste can migrate away from the center of the silicon die (the pump-out effect). This creates microscopic air gaps that act as insulators, preventing efficient conduction to the heatsink. Applying a high-viscosity non-conductive compound restores the thermal bridge necessary to keep the CPU within its operational TDP window.

Mainboard (System Board)
In rare cases, the Power Management Integrated Circuit (PMIC) or the Embedded Controller (EC) fails to correctly interpret thermal sensor data, or the voltage regulator modules (VRMs) overheat and trigger a safety shutdown independently of the CPU core temperature. This represents a total failure of the board's power-delivery phase and requires a full logic board replacement.
