A coil whine problem, please take a look!

Hello, I have been getting a terrible coil whine THROUGHT my headset for some reason. Pretty sure it is coming from my GPU since when I am in a game the pitch/loudness changes when I change my FPS cap. (When I cap my FPS at around 120 or something for example it's not that loud, but I use a 144hz monitor and I play some games at a competitve level so I need to get max out of my PC.)

I am not too sure why it is leaking into my headset nor why it's that awful, but will buying a new headset (Hyperx Cloud II) fix the issue? It has an USB audio card to it. (I think that's what it is at least) I currently am using another Hyperx headset but I have it plugged into a 3.5 jack.

Also, the coil whine isn't a problem when I take my headset off, It's basically not noticable at all, but when I put on my headset it's literally a nightmare.

Edit. Forgot to mention, I have my headset connected to the front of my PC, when I connect it to the back coil whine seems to go away completely, but my headset is displayed as speakers and audio is really low..

Also, after unplugging the monitor the coil whine seems to go away. I don't know if its relevant or not but I thought it's worth mentioning.

I just opened my PC while being in game and reduced my fans to hear if it's coil whine coming from my GPU and it is, it wouldn't be a problem if it didn't leak the sound into my headphones.. Why the hell does that do it LOL

That's interference rather than coil whine. If you had to turn the case fans down and open up the case to hear it that noise is probably pretty normal. The problem is you're getting interference through your headphones for some reason. Have you tried normal speakers to see if it does the same? If same with speakers, maybe try moving GPU further away from where the sound ports are.

You haven't said when the noise started either I don't think. Is it a new GPU? Or is the setup the same but it's just suddenly producing noise through the headphones?

Have you tried checking the sound options in the control panel?

It's a PC I've had for around a year ago but the only game I played was CS:GO, which didn't produce any hissing noise in my headset, even tho my fps have always been very high. I started playing fortnite and wow around 2 months ago and that's where the problem started.

The sound my GPU produces (coil whine I'd say, not a big one anyway when I have my pc case closed I can't hear it, unless I have my headset on haha) is basically exactly the same I hear in my headphones. The higher FPS, the louder the hissing (both inside of my case and in my headset).
Back rear jack doesn't have the hissing anymore, but the volume is way too quiet for me and my PC detects my headset as speakers (I am guessing that's normal for back rear) and I can't play with it.
I have 3 other pairs of headset at home, the issue happens with all of them (all high end gaming headset)
Control panel settings are all good.
Also when I mute everything in Sounds and I can't hear anything on my computer, the hissing is still there.

Sounds like the cable connecting your motherboard to your front panel is subject to electromagnetic interference. The cable could be poor quality, issue could even be on the motherboard (less likely). Can you route that cable in a different path and see if that reduces or gets rid of the issue?

An external DAC like a cheap USB sound card or USB headphones like the HyperX Cloud II will indeed eliminate this issue.
I've tried messing with the cables a bit but I'm honestly clueless when it comes to what's inside the PC and I don't want to mess it up haha, I've ordered Cloud II and hopefully it fixes it, will update after I recieve them I guess. :p

i used to get sound interference when i moved my mouse on my old motheboard / onboard sound both through speakers and hdmi.

i never got to the bottom of it, but it went away when i got my new system with an asus gaming mobo.
I've got a pretty high end asus gaming mobo and it's happening hah, hope it goes away when i get my hyperx cloud 2s

actually thinking about it my problem mobo was asus... my new mobo which is ok is gigabyte!.... luck of the draw i guess

P8P67 pro gave me issues
GA-X99-Gaming 5P (no issues and by far the best sound i have ever had - soundblaster certified if that means anything these days)
I just hope USB headset fixes that ****, it should honestly but we will see when it ships :p
