Warranty still OK with full permission from Gigabyte to remove air cooler.

Tested with same settings and duration. 4K PC gameplay on the original air cooler at max GPU voltage and Core overclock 3000Mhz and Memory Overclock 11500Mhz.

Results were very good for a simple thermal repaste.No need to replace thermal pads.

I own a few RTX 4090's they all get hot spot temperatures over 100℃ when pushed with max GPU voltage and 570+ Watts
