Acer Predator Orion 3000 Po3-630 makes annoying noise! What to do?

I have recently bought a desktop. And it makes annoying high pitched noise! I checked all of the fans by stopping them and still the sound exists. Disconnected gpu still noise. It is not coming from psu, I think it is coming from Motherboard but I don’t know what to do, it annoys me:(

That noise is probably coming from the oem 1x cpu cooler fan as its working overtime to cool the 11th Gen cpu, but all desktops are noisy and especially a desktop like the PO3-630 with so many fans. The only thing that you can do is change these case fans and especially the oem 1x fan cpu thermal cooling system that is probably working overtime to cool the cpu down with a more efficent cooler and a quite =er cooler.

What I suggest is that you change the cpu thermal cooling system to the more efficient Noctua NH-U9S cpu cooler which its fan will work far less and not be so noisy and also change the case fans to a quite range of case fans like the Noctua range or the be quite range of case fans, which will decrease the noise levels of your desktop by at least 20+ dBA. Good luck and hope this helps you out .

If you have tried those things then the fans, PSU and GPU should be good.

Sounds like coil whine to me, but usually it comes from the GPU under heavy use. Does the noise change when you stress your CPU?

You could try another power outlet, remove and install only one RAM stick at a time (just in case), but I don't think that will help. If you have two storage drives try them one at a time…

Well, I'm afraid that the only thing you can do is to replace the motherboard or even better, return the whole system. :(

Otherwise known as coil whine from induction coils on the mainboard that gets louder when under load. If your hearing is half-way decent, you should also be able to hear higher pitched hissing sounds mixed in with the racket from smaller inductors and the fans when the cpu and gpu start to heat up.
