Vapor Chamber Heatsink Assembly
The primary failure mode is a manufacturing defect in the cooling solution where the vapor chamber was underfilled with coolant during the sealing process. This creates a breakdown in the latent heat of vaporization cycle, as there is insufficient fluid to maintain the capillary return flow to the evaporator zone above the GPU die. Replacing the integrated heatsink assembly with a unit from a corrected production batch restores the necessary phase-change efficiency.
