Hello,
 
I have a 3090 FTW3 Ultra and i read i should have an OC button to adjust fan settings. Is this a physical switch and if so where is it located?

    It's on the long side of the card. You can't miss the cut out on the backplate with writing on it.

    I also read not to switch it if the computer is on. Only when off.

    Could you please explain what that OC BIOS does or just post a quick link, if you have one? I have the same card and won't overclock the card anytime soon, but would that switch provide any other benefits?

    I have the same card.  What exactly does moving the switch to OC do?  I havent found a reason for needing to OC it yet, but I cant find any instructions on what actually happens when that switch is flipped.

    All it is is a more agressive fan profile for those that don't want to mess with settings.

    You can switch it while booted, but the change won't happen until you restart the computer.

    Thank you, I already set up the fan profile in X1 manually, so I guess no need for that switch on my end.

    Same - First thing I did was setup custom fan curve.  Thanks for the response @arestavo.

    I checked the OC VBIOS in GPU-Z and it IS showing a slightly higher max power limit - 450 watts. The other VBIOS showed 440 watts.

    I had no idea there was a physical switch, god I'm oblivious.
