Support said they would forward my request to the Tech team, but i got a bit impatient waiting so I found and cross referenced a few BIOS'es from the provided links and chose one that was an identical version match and flashed my card with it, just fine. So now it seems to be back to stock settings.
I also installed Afterburner so i could set a slightly higher fan curve and maintain full boost clocks without throttling. And I have my three 120mm intake fans slaved to the GPU temp by way of corsair iCUE, which should ensure more than enough fresh cool air entering the case.
My main reason for doing it like this is because my system is a Windows XP/10 bual boot system. With XP-era games being infinitely less demanding, stock fan curves are perfectly fine.
