Weird Coil Whine GTX1080

[Mcwrah]

Hey this is my second post about coil whine... After changing out psu that slightly caused coil whine it was reduced by half but it was still loud and audible through headphones. So I changed from MSI Gaming X to asus strix aaand I still get coil whine but its a bit different...at 95-100% power its loud but not as loud as the gaming X (cant hear it through headphones), and sometimes just as loud(can hear through them on occasions). Tts constantly as loud as the gaming X when i let it go to 120% power draw and OC it, also happens at 80%+ gpu usage. Any idea what can be causing this issue? Its not that big of a deal anymore but it still bugs me. If its GPU coils causing it, I wont bother with it. But could it be caused by my MOBO since the sound is coming from the gpu/ somewhere near the gpu itself? Another thing I noticed is, when I put it into heaven benchmark or valley or even 3dmark (except firestrike combined test) and its not that bad, its barely audible. It only becomes noticable in games like Witcher 3 or when both GPU and CPU are being used a lot (GTA V, Crysis 3).And yes i tried the psu in my friends PC which has old AMD card that eats 200tdp+, the psu is completely silent. PSU is EVGA SuperNova G3 750W and mobo is MSI z97 gaming 5. As a bonus before on my 2nd GPU it was caused by fps, the 3rd one and this one can have up to 1k fps without the sound changing, it gets higher pitched and louder at 2k and up and thats very rare


Side note: this is my 4th GTX 1080 and only this one is silent enough with coil whine to not be audible through hyperX clouds without anything playing in background. The noise is not as high as when i have high fps, its a bit lower frequency than the high fps whining, its more like HDD sound yet its higher pitched than that, its not the hdd since i have one and tried just with my ssd and it was still there.
Thank you all in advance

You can always limit the FPS to 60 if it goes above that on load above 80%+ as you said, see this video https://www.youtube.com/watch?v=jtXAuIJchps
