Could a failing Replacement CPU Cooling Fan cause the MSI RAIDER GE78 to have symptom: Overheating Shutdown?

The thermal management system relies on high-RPM centrifugal fans to exhaust heat from the fin stacks. Mechanical failure of the fan motor or internal bearing friction prevents the system from maintaining the required CFM, leading to rapid heat soak and subsequent emergency thermal cutoff (ETC).

Could a failing Honeywell PTM7950 Phase Change Thermal Pad cause the MSI RAIDER GE78 to have symptom: Overheating Shutdown?

High-performance laptop dies experience significant thermal expansion and contraction. This phase-change material liquefies at high temperatures to fill microscopic voids and solidifies to resist the 'pump-out' effect common in standard pastes, ensuring long-term thermal conductivity between the die and the copper heat pipes.

Could a failing Replacement GPU Cooling Fan cause the MSI RAIDER GE78 to have symptom: Overheating Shutdown?

In a shared-pipe cooling architecture, the failure of the GPU-side fan significantly impacts the overall thermal equilibrium of the system. Even if the CPU fan is functional, the lack of airflow across the secondary heatsink causes heat to back-flow through the shared heat pipe array, triggering a system-wide shutdown.

What is the most likely root cause for a MSI RAIDER GE78 with symptom: Overheating Shutdown?

The thermal management system relies on high-RPM centrifugal fans to exhaust heat from the fin stacks. Mechanical failure of the fan motor or internal bearing friction prevents the system from maintaining the required CFM, leading to rapid heat soak and subsequent emergency thermal cutoff (ETC).
