The End of Thermal Paste Pump-Out on Modern GPUs

High-wattage modern GPUs (300W+) experience microscopic thermal expansion and contraction cycles that push standard thermal paste away from the die center within 6 months. Honeywell PTM7950 phase-change material melts at 45°C, filling microscopic voids permanently.
