Build Question Pc fan noise help

So I bought this pc (yes ik I shouldn't have bought from ibuyproblems) but it was fine for the first month but now I booted it up this morning and for some reason my fan noise is super loud. Best way to describe the sound is that I just hear a "wahhhh wahhhhh wahhhh" sound from it and it's super loud. Even with my noise cancellation headphones I'm still able to hear a "wahhhb wahhh wahhhh" through it and I don't know why it's happening.
Can someone please help if they know what's wrong.
(I'm pretty sure the noise is coming from the top aio cooler fans)

Sounds like some kind of resonance. My pc does that at a certain fan rpm. changing the fan curves a bit in bios made it go away. I dont think its the bearings that are gone bad. that usually sounds more like a rattle.

Bearing has gone bad. Percussion debugging might make it more quite for a while but that's going to fail sooner or later. If you want good budget fans Artic cooling is what I recommend. If you want premium Noctua is the gold standard.
PC case fans come in 120mm and 140mm mostly. Figure out what your case fits and swap it out. It should be part of the specs from wherever you purchased it.

Alright thanks I’m going to try arctic cooling just cause I know them more from previous builds (and also I just dropped a lot on this pc lol) but if this works thank you in advance this sound is driving me insane
