Omg.... I had the EXACT same sound on my old PC and COULD NOT find this issue. I think I had isolated it down to the GPU. What is your GPU?

[d3sl91]

yeah, Coil Whine. Every computer I have built has had it. Either from the GPU, PSU, or Motherboard.

 

Can you hear it over the fans?

[Yiz]

coil whine i guess the audio isnt clear

doesn't sound like coil whine though at all.

Edit: actually it could be, but I had the same sound and it wasn't coil whine.

What did it end up being?

 

Coil whine can sound tons of different ways. Loud, soft, different pitches. Sometimes Screeching sounding, sometimes a really high pitched "wheee". Depends on the coils, what they are resonating with, how much power is flowing, etc.

How did you record this? Is this from inside the case, or is this a recording of what your audio output sounds like?

[nicolas2465]

This is recording inside the case next to the CPU area.  From what I've read it could be from the motherboard itself.  I'm sitting here typing this and I have a headache from this god damn sound.  

[Altecice]

Yeah thats Coil While alright. Check the motherboard VRM's (part near the socket with the heatsinks) /GPU/PSU.

Update: The noise stops when I run prime95

Yeah, it's coil whine. Its changing as more power is flowing. 

 

Unfortunately, there is not much you can do. You may be able to overclock the cpu and see if that removes it, as the voltages will change with overclocking.

 

Othwerwise, Having the side closed and fans running, you still hear it? My system squeals, and the only way I hear it is with my side panel off an my ear in the case. 

[Tenge500]

Lol, I've had this for a long time. I thought it was normal. oO

[WinNut]

It's probably coil whine from the CPU fan (since you said it's near the CPU).

 

And yes, as the fan speeds up the coil whine leaves the hearing range of a homo sapiens, so it seems to stop.

What Bios setting are your fans on, mate? Turbo?

[LabRat]

disconnect system fans and try again/

[nicolas2465]

I got it to stop by disabling all power savings modes in the bios and disabling C6 states.
