Hello! Yesterday I bought a new GPU, PSU and Monitor. Until then, I was on integrated graphics card and older weaker psu. When I bought my new MSI R9 270x gaming 2GB, Fortron Hexa 500W and connected them in my PC I noticed when talking with someone over microphone while I'm in game, that from my side the other people can hear irritating noise from my microphone. And the pitch of the noise warries when FPS goes up and down, it's a lot more irritating with high FPS but still present as low pitch at low fps. I researched bit about that and found about Coil Whine term.

Is there any way I can get rid of that? What should I do?

My current setup is

Pentium G3258
Asrock H81M-HDS
Fortron Hexa 500W
MSI R9 270X Gaming 2GB
WD 250GB

Normally that wouldnt be a problem if I don't need to talk with others while I play, and I also make YouTube videos and recording my voice while I play. I didnt have that problem when I was on iGPU and old PSU.
 
Coil Whine is common with video cards. Some monitors have a high pitch sound too-mine does that sometimes. I would try and locate where it is coming from first. If it is coming from the GPU, there isnt really a way to get rid of it - RMA. Once in a while, it could even be the power supply. Locate source of noise and report back.
 


So the best way to do that is to open the panel enter a game and listen where is it comming from? What if I can't locate it? I mean I hear it only when I listened to my mic.
 


Yes. In order for me to figure out the problem, I need to know what component is making the noise. There are many factors that I can think of with that noise. If you cannot locate it, try playing a game with the headset turned off and playing with friends. From there, if they cannot hear it, it elimnates one factor: your mic.

If it is still audible, try running a benchmark. If the noise continues throughout the benchmark, I would assume monitor or GPU.
 


I opened up Counter Strike Source and stayed in menu, and set FPS max to 60 and then to 1000. On 1000 it is really really high pitched so I kept switching it from 60 to 1000 while having my ear near the case. But there is no sound like I hear in headseat when I enable "Listen" option on my mic, there is no sound like that comming out of my PC case. So it's only happening in games and the pitch depends on FPS. My headset is 3 months old so it's not broken since it was working perfectly before I upgraded my PC yesterday. I would narrow it down to either PSU or GPU although I cannot pinpoint it. What am I to do? I want to make this annoying sound go away. Should I go in the store and ask for a new power supply? Or gpu?
 


If you cannot here the noise without the headset then most likely its your monitor or head phones. First test GPU. Replace it, see if it works. If nothing changes, replace PSU. If nothing changes, try playing without the headset and see if the noise persists.
 


That is correct, however the PSU is new, so is the GPU. The entire system doesn't use more than 300.
 


Would it be best if I go to the store, return the current Fortron Hexa 500W 80+ PSU I have now and try to replace it for XFX TS 550W?
 


Watch this.

I recorded 30 seconds of this sound

I have older Energon EPS 650W that I had before I bought this Fortron. So I'm gonna switch them boot up and hear if there is still this problem. And turn off my upper exhaust cooler of my PC case, it produces small vibrations. Gotta figure out what's causing it. I'm so nervous because this problem shouldn't exist and it's bought new. 🙁
 


I actually opened pc panel and went in the same game trying to listen if there is any sound comming from any of the components while I move mouse and make FPS go up and down.

It is definitely comming from GPU and that is coil whine. I really doubt new PSU would fix this one I'm afraid :/

Anyone else had same problem?


It was not even hearable until I opened the panel on PC and start listening but for some reason my mic picks this sound and it's louder on my headset than I can normally hear it without headset.
 


Is it possible to return it to get another one? Since it's bought like 3 days ago.

And thank you very much for your assistance, I saw some of your answers with some other problems I had before and I really appreciate your effort to help people out with their problems on this forum.
 


I would try to return it.


 


I went to RMA it, got it replaced, came back home, installed it, aaaaand the coil whine is still there....I can't hear it normally like this and when playing, but for some strange reason the soundcard picks up that sound and when I'm using my mic that sound is here along with my voice. Should I buy some cheap usb soundcard and see if that fixes my problem.
 


It obviously isnt the Power Supply. Have you tried replacing the GPU or monitor? Personally I would try GPU.
