I started off the day at #41 and just out of sheer boredom, I wondered how high up I could go so a day of GPU torture began. I don't know how on earth this ended up to be so stable but it works. Average temp settled at 56°C which I wasn't expecting.
I don't know how much more I can push it since I feel like I was right on the limit.
Either way, I'm super happy it's managed it for a budget build/second hand parts machine.
