Honestly, I've spent way too much time obsessing over VRM and VRAM temps because that is what usually fails first during 48-hour render marathons. My journey started with stock air coolers but I kept hitting thermal limits that made me paranoid about my hardware lifespan. For absolute reliability, I moved to a setup that focuses on component safety rather than just chasing the lowest core temp. Here is basically what has worked for my peace of mind:

• Swapping stock case fans for Noctua NF-A12x25 PWM units to ensure 24/7 static pressure without bearing failure.
• Installing a high-end AIO like the Arctic Liquid Freezer II 360 which includes a dedicated VRM fan to keep the power stages cool.
• Undervolting the core slightly via software to reduce heat soak into the PCB while maintaining export speeds. Its reallyyy about making sure ur card doesn't suffer from thermal cycling stress. If the temps are swinging from 30C to 85C constantly, that is when things start failing over time. Keeping it steady and cool is the goal for a long-lasting editing rig.

For intensive video editing, a well-cooled GPU is crucial. Air coolers can suffice for many, but demanding workloads may benefit from liquid cooling for consistently lower temperatures and potentially longer lifespan. Ensure adequate case airflow regardless of your cooler choice. My liquid cooler keeps my RTX Pro humming along smoothly even during 8K edits. Sharing your specific GPU and workload helps tailor recommendations!
