Noise (Maybe coil whine?) when shutting down PC

[Marfe]

 

Yesterday I noticed that there is some noise when I’m shutting down my PC.

 

I thought it was my GPU because I just recently upgrade from a GTX 1060 to a RTX 2070. But i tried reinstalling my old GPU but got the same result. I’m definitely sure that it’s not from the PSU because I removed the PSU shroud and stick my head into it but when I hear it it’s like on the upper part of the PC (when my head is right beside the PSU). 

 

I’m thinking that it’s because of the BIOS update that I did on my Motherboard (I updated the BIOS when I formatted my PC and installed a fresh copy of windows). I’m not sure.

 

Things I did to troubleshoot:

- Swapped my GPU

- Unplugged my mechanical hard drive

- Removed my overclock

 

Haven’t tried rolling back to the previous bios tho.

 

Is this a bad thing? I tried running firestrike for 1 hour and had no problems with it. I’m just concern.

Sounds like a HDD... Try unplugging the HDD(s) and seeing if it still happens.

@Marfe
that's pretty normal, not sure what is the sound exactly, but it could be capacitors depleting because there's ALOT of capacitors on motherboard, GPU, CPU, PSU, i have the same sound too, and i've had it on all of my computers.

I’m just worried that THAT noisy part might damage other components of my PC.
