Question Computer making extremely loud sound.

[WhirlBarbarian]

My computer has been perfect. The last component I added was my x52 kraken AIO. And that was back in December. Nothing was wrong. And then I decided to download MK1 because I've been really wanting to play it. It starting making an ear piercing sound. I thought it was coil whine but everyone I asked said it was WAY to loud to be coil whine and said it was more likely a dying HDD. I took out my HDD and my AIO and it continued to make the sound. I was told to, undervolt my GPU and to enable, "Acoustic Sound" in bios for the motherboard. I haven't tried either, but I'm really worried it's my GPU. It's none of my case fans or the gpu fans. I turned them off and checked all of them. The sound will randomly turn on even when my computer is idle. But when I start my computer I was able to do work for 8 hours without it doing it until I turned on MK1. But after I closed it the problem persist. It can go from 2 seconds to like 30 seconds at a time. It sounds like a really loud zipline. I have a Asus B550, Ryzen 7 5800x3D, EVGA 2080 ti, and a EVGA 850w Gold. I also have 16gb of ddr4 ram, 3600mhz. BTW, my pc works completely fine and the temps stay the same during idle and during playing MK1

Not many moving parts inside the PC. HDD and fans.
Other noise sources include vibration noise, airflow, coil whine, cable rattling against fan blades. None of the four are high pitched loud noises.

I suggest that you open up your PC case and put your ear to it, to locate from where the screeching noise comes from. But at current moment, i'd suspect fan bearing, including AIO pump bearing.

I took out my AIO and the only fans left in the case are my gpu fans. The noise seems to be coming from the GPU itself. This morning I turned on my computer for work without loading anything up besides a show and it'll make an occasional screech at different pitches. After typing that sentence it made another screech and I looked at it and it looks like every time my second fan activates it makes that sound. I'm gonna do more testing afterwork and truly see if its the fan or not.
