So at first i thought i had the coil whine issue but afyer messing with the fan curves no amount of adjusting seems to fix it. I started playing with the power and noticed that when the usage is around 45% I get a noise that sounds like electricity and get louder the closer my usage gets to 100%. idk if Im going crazy and this is normal or if there is an issue with my card.

    The thing is even if you disable the fans its still there and it’s directly affected by power usage.

    Yes, and that is coil whine.

    Even if you are at idle with no noise and put the fans at 100% and there’s still no noise?

    Coil whine is electric not fans. People talk about fans in relation to coil whine because fan noise is often mistaken for coil whine. If the noise doesn't stop when you stop your fans then it is likely to be actual coil whine. This is known issue with 3080s and some power supplies.
    Things to Do:
    Make sure your power supply meets the minimum wattage that EVGA lists for the card you have. If you are overclocking at all make sure you have room above that minimum. The general consensus from people who understand power in performance systems (not cheap recommended builds from reddit) seems to be around a 750 watt power supply. Even then you may get coil whine from some.  There is another thread here that addresses this issue. I believe the title is something about posting working power supplies or something to that effect. Check that thread and see if your power supply is listed as one that reliable works.
    Also, If the power supply is 7 years old or more you should probably consider replacing it anyway. Power components age and some age better than others. If you have a 10 year warranty power supply you could try talking to support about the coil whine and see if they will do anything. Some companies cover it and some don't.
     
    Edited to add: If you can borrow a strong enough recently manufactured power supply from a friend you should test it with your system and see if it goes away. This may help you determine if the problem is your power supply or your card.

    Coil whine is related to how much power the card is drawing, and not how fast the fans are turning. The fans do little in the way of drawing power; the GPU itself is responsible for the vast majority of power draw.

    Thank you this makes way more sense than the other threads that I have read. And my pay is Corsair Rm850x and I haven’t seen that thread I’ll be on the look out for it.

    The RM 850X is a very well reccommended power supply.

    I had the same problem with a EVGA g+ 1000W and 3090 FTW OC'ed. The whine was so loud it sounded like it came from my GPU. It actually was from the PSU. I RMA'ed the PSU and everything was silent after.

    I’ve tried listening to psu and I can hear it by psu but it’s louder by my gpu so idk if it’s that but I’ll look into
