so i noticed a fan rattling a lowish rpm this morning! I dialed it down to fan 3  when fan 3 is under 50% it rattles, when its above 50% it goes away, heres my settings:
 

 
Here what the fan rattle sounds like: https://www.youtube.com/w...;ab_channel=brandonb56
 
make sure your wearing headphones and volume is loud ish, it almost sounds like electrical noise/coil wine. This video was taken while at windows desktop no game or apps where running, if i turn fan 3 off the rattle goes away. Fan 1 & 2 are quiet at ANY rpm level no rattles, just fan 3!
 
What would you do ? request a RMA ?

    Post a picture of your fan curve for each of the 3 fans. I only heard coil whine

    why would it be coil wine only when fan 3 is below or at 50% thats strange?

    it's a firmware bug. google "evga 3080ti 3rd fan clicking"  and you will get a bunch of posts on this forum about it.
    a new post like this appears every few days.
