High frequency buzzing from gpu and psu

[Nightz]

I recently built a pc at Christmas which I was very happy with. But after launching a game I realised that a strange noise was coming from my psu. I'm not 100% sure about the noise then but it was a low pitch buzz I'm also not sure if it was coming from the gpu aswell. That psu was the rm750x and gpu the gigabyte 1060 3gb recently after rma'ing the psu the first time the noise had change to a higher pitched buzz and was better then the otherone, this time it was noticeable that the sound was coming from the gpu and the psu but I thought I got unlucky so I tried to Rma again (3rd time lucky) but yet again the same as second but even worse in loudness and the fan was also bad in the new psu. So I decided to send it back get my money back.

Once I received my money I went to buy a evga G3 750w and with this one which is alright but still whines. The psu buzzes when idle or browsing internet. (This is very quiet have to put my ear to the vent)
When playing games the psu buzz increases abit and the gpus high pitch buzz is there. I've noticed that the buzzing/whining is different pitch between the gpu and psu
I've heard all psus coil whine to some extent. Putting on vsync does decrease the frequency. This noise doesn't annoy me in sound as I can't really hear it. It's just is it damaged or getting damaged?

Note : 1st (CORSAIR) psu low pitch buzzed
2nd, 3rd (CORSAIR) higher pitched buzz with gpu aswell
4th (EVGA) same pitch as 2nd,3rd but gpu and psu make different pitches.
Any help or thoughts appreciated!

Mobo : Asus Maximus VIII Hero
CPU : I7 7700k
GPU : gigabyte GTA 1060 3gb
PSU atm : EVGA G3 750W
RAM : 8gb of corsair vengeance 2133

PS : I'm starting to believe it's not the psu and maybe something else or even it is normal my 2 friends both gpu and psu buzz. I'll try and compare the sound loudness at 100 - 120fps on Fortnite about 30cm away it is just hearable then 60cm very quiet and above that is silent or it just blends in with fan noise.

You should really stick with only one thread. I can already tell this is related to your last discussion, and whether you were getting help or tips, it's just unnecessary to create more threads regarding the same topic. I've already learned that in the past.

Sorry, I'm just worried

This is either fan noise caused by dodgy motors, damaged or dirty blades or more likely based on your comments, coil whine. Fans can be replaced or cleaned if they are the culprit, if it's coil whine there is no cure, it does however pose no risk to your system.

If it is coil whine you either live with it, fit sound proofing to the case (which will increase component temps and likely increase fan noise defeating the object), wear closed back headphones or replace the components.

The only other thing I can say is if it is coil whine, the less load you put on the system the lower the pitch of the noise generated, consider installing MSI Afterburner and setting an FPS cap to just over the frequency of your monitor (70FPS for a 60Hz monitor or 130 FPS for 120Hz).

This will prevent your GPU working at full pelt so instead of generating 100's of FPS on a 60Hz monitor it will cap the FPS andl reduce the load on the GPU and also reduce the level of whine.

I'm pretty sure its not a fan but I can live with it I'm getting the fractal design define r5 case. And I've read sometimes new psu's need weeks or even months to settle down but cheers for the info and help
