My Gigabyte RTX 5060 is hitting thermal limits in complex lighting scenes in Indiana Jones, causing lag. Should I fix the airflow?

Using a Gigabyte RTX 5060 for 4K in the Ancient Circle is like trying to put out a forest fire with a desk fan. Core temps were hovering between 88-92°C, and clocks plummeted from 2500MHz to 1800MHz—the performance loss was honestly pathetic. I tried 'Prefer Maximum Performance' in the Nvidia panel, but power draw maxed out and temps hit 95°C, causing the driver to crash. Total waste of time. I manually set an aggressive fan curve, hitting 80% speed at 70°C, and added two exhaust fans to the top of my case to create a strong positive pressure flow. GPU-Z finally showed core temps stabilizing at 74-79°C and clocks tightening to 2400-2550MHz. The screen tearing is gone. I did notice my PSU fan was fighting the new airflow at first, but flipping the PSU orientation fixed it. VRAM stays at 82-88°C and core power is 130-150W. I backed up this config, and VRAM remains steady at 82-88°C.
