ACER PREDATOR HELIOS 300 Overheating

High-Performance Thermal Interface Material

The original silicone-based thermal paste undergoes thermal degradation and 'pump-out' over time, increasing the thermal resistance between the processor die and the copper heat pipes. Replacing this with a high-viscosity non-conductive compound restores the intended heat flux. This is the primary corrective action for thermal throttling in high-TDP gaming laptops.

CPU/GPU Cooling Fan Assembly

Mechanical wear of the fluid dynamic bearings or excessive dust accumulation on the ultra-thin Aeroblade fins reduces the fan's RPM and airflow efficiency. When the fan cannot maintain the required static pressure to push air through the radiator fins, heat saturates the heat pipe assembly. Replacing the fans ensures the system can effectively exhaust the 45W-90W of heat generated during peak operation.

Copper Heat Pipe/Heatsink Module

In rare cases, the internal vacuum of the sintered copper heat pipes may be compromised by a micro-fracture, causing the working fluid (usually water/ethanol) to leak. This results in a total failure of the phase-change heat transfer mechanism. If temperature deltas between the CPU and the far end of the radiator remain extreme despite fan and paste replacement, the assembly must be replaced.
