High-Performance Thermal Paste (Non-Conductive)
The factory-applied thermal compound on the 16-inch models is known to dehydrate and crack over time, creating an air gap between the CPU/GPU die and the heatsink. This leads to rapid heat spikes that exceed the T2 controller's threshold, triggering an emergency shutdown. Replacing this with a high-conductivity TIM (Thermal Interface Material) restores efficient heat transfer.

Internal Cooling Fan Assembly (Left/Right)
The high-RPM requirement of the 16-inch chassis leads to bearing wear or dust compaction within the fan housing. If the fans fail to reach the target RPM requested by the SMC during high-load tasks (like video rendering), the system will shut down to prevent permanent silicon damage.

MacBook Pro 16" Logic Board
If thermal maintenance fails, research indicates the 2019 16-inch model frequently suffers from failures in the power management ICs or the T2 security chip's thermal monitoring rail. This results in 'kernel panics' and shutdowns even when physical temperatures appear manageable, requiring a full board replacement.
