MICROSOFT XBOX SERIES S Overheating

High-Performance Thermal Interface Material

Over time, the factory thermal paste undergoes 'pump-out' and desiccation, creating microscopic air gaps between the APU die and the copper heat spreader. This significantly increases thermal resistance, preventing the heatsink from absorbing heat as quickly as the silicon generates it. Replacing this with high-thermal-conductivity paste restores the conductive path, allowing the cooling system to maintain the junction temperature within safe operating limits.

Internal Cooling Fan

The Xbox Series S relies on a single high-diameter radial fan to create a pressure differential across the internal components. If the fan's fluid dynamic bearings experience increased friction or if the PWM (Pulse Width Modulation) control circuit on the fan's PCB fails, the fan will not reach the required RPM to meet the thermal load. A replacement ensures the volumetric airflow (CFM) meets the engineering specifications for peak load cooling.

Heatsink and Heat Pipe Assembly

While rare, the vacuum-sealed heat pipes can experience a loss of hermeticity (slow leak of the internal working fluid). If the working fluid escapes, the phase-change cycle that facilitates rapid heat transfer from the base to the fins is broken, leaving the assembly as a passive, inefficient block of metal. This results in rapid heat soak and subsequent thermal shutdown under load.
