Question What is causing whine in my PC

[McBes]

So I just upgraded my case and motherboard today from b150m to a z270 tuf mark 1,and as soon as I turn on the pc I get this very loud whine most likely coming from the motherboard. The pc works and boots to desktop fine. I removed the GPU to make sure it wasn’t it.
please someone give me a reason for this and possibly a solution. If the motherboard is faulty please let me know!!!

here is a clip :

Stop each fan with your finger while the computer is on to rule out a bad bearing.

I know it’s not the fans but I did it anyway for the heck of it...no use 😔

Could it possibly be a badly seated cpu?when I put my ear to the be quiet cooler it gets louder.

CPUs either seat correctly, or you damage them when you lock them in so it's not that. If the noise is coming from around the CPU it could be a VRM making the noise, if that's the case there not much you can do.

In BIOS when I turn the cpu fan on max the sound stops this is so bizarre, yet when I hold the fan with the finger nothing changes, now I’m more confused

Hmmm. Can you quickly swap the CPU fan with another fan then see if the noise persists. Its definitely strange.

I will swap the cpu cooler fan tomorrow and see what’s gunna happen,unfortunately if you’re asking for a different cooler then I don’t have one.

No just the fan. There should be anything in the cooler itself that is capable of making that noise

Could be your PSU. Put your ears to the side of the PSU. It normally isn't too hard to figure out where a sound comes from using your ears close to each component. Could be GPU coil whine

The sound stops when I turn the cpu fan in bios on max so it has to be something with that region?
