Internal CPU Cooling Fan
The most common mechanical cause of the 90D thermal shutdown code is a failure of the fan's fluid dynamic bearing or dust accumulation in the heat exchanger fins. This prevents the dissipation of heat from the thermal pipe, triggering a failsafe shutdown to protect the silicon.

High-Performance Thermal Interface Material
Factory thermal paste on the Pavilion 15 series is known to desiccate over 2-3 years, creating an insulating air gap between the CPU/GPU die and the heatsink. Replacing this with high-conductivity paste restores the thermal bridge required for effective cooling.

Replacement Motherboard (System Board)
Research identifies a pattern failure where the APW8858 power management IC on the motherboard overheats due to internal shorts or failing MOSFETs in the power rail. If shutdowns persist after fan replacement and repasting, the IC failure is the definitive root cause, requiring a board-level swap.
