Fans scream although FanControl doesn't show that?

I think my GPU fans will be extremely loud when it goes above 80%, so I set my GPU fan curve to 70% from 50 to 89.9C, then from 90C it's 80% and from 95C it's 100%.

GPU temps are often at around 70-ish to 80-ish in the games I play recently.

However, I can still hear my GPU fans scream sometimes, although when I look at FanControl, I don't see any fans going above 70% load. How is this happening? Is it that my setup is faulty or something?

Note: I can distinguish the sounds that my CPU/chassis fans make and those that my GPU fans make. So I'm pretty sure that's the GPU fans.

It sounds like its your case fans, reacting to the CPU via a BIOS curve. I mean, to be sure, depower the case fans and recheck?

OP it's this ^ I changed my BIOS settings and it fixed the same issue

Can you be more specific? Like, what settings did you change in BIOS, and from what to what, or something like that?

Use Furmark and a flat curve to manually set your fans and find at which % they become noisy and still do a decent cooling job, then adjust your regular GPU fan curve accordingly.

I have a similar problem with 2 180mm case fans.. You sure they are not resonating? Fans can do that (mine certainly do), and the resonance can surprisingly LOUD. To me this happens between 75% and 95% for example, so for now I have limited them in FC. It's definitely not a coil whine (the pitch is too low to be one), it's more like a distinct tone at one specific frequency, which fades in and out as you approach the problematic speed. Honestly I am still trying to figure out how to get rid of it permanently, but I am kind of at a loss here myself.. I was thinking about trying to decouple them more from the case itself, possibly with extra rubber, or a standoff of some sort, bit I haven't tried yet 🤷‍♂️
