High pitch noise around cpu area

[sergiuskater]

So i have an Asus h110-m r as my motherboard with an i5 6600 and it makes a constant high pitched noise which doesnt stop until i stop the pc. First i thought it is the power supply but i took it to a computer shop to test it and they said theres nothing wrong with it (seasonic s12ii 520). Now, i dont think the sound means something bad but its driving me nuts.

The Mosfets are making those sounds. There couple of reasons to narrow it down does it still do it when the graphics card out because sometimes the gpu makes the high pitch or buzzing sound or sometimes the motherboard, when it's not getting enough power or when the power supply is getting pushed and the motherboard it reacting to it. Or it when example Asus use cheap mosfets/ components, If you have a gpu take it out and power it on if it still make the sound, the mosfets are making the noise and the really good way of making it go away fast and for good it to buy a higher end ones boards or slightly better or in opinion another board brand. If the sound is gone when the gpu if you have is out then I most likely the power supply yes seasonic a good brand but usually the power supply's in the 50-60 dollar range and that model is in that range have the coil/mosfets high pitch sounds.

Yeah i tried without the gpu and it still makes that sound. I dont really want to spend money only because of this sound but it would be nice if i can solve thia without money

I herd some tricks but there is just lot of things that can cause it. some people say it a power management issue I don't think you have that I just think it that they are either not good quality or under spec. And my mistake the things with the high picth noise are coils not mosfets because some times I have people calling those mosfets when they are coils. And they make that sound when they are vibrating there is a way to fix by putting clear nail polish on it but I think it works only with these styles https://www.google.com/imgres?imgurl=http%3A%2F%2Fwww.ixbt.com%2Fmainboard%2Fecs%2Fa780gm-a%2Fvrm.jpg&imgrefurl=http%3A%2F%2Fixbtlabs.com%2Farticles3%2Fmainboard%2Fecs-a780gm-a-780g.html&docid=ogDOJXP2i7WVZM&tbnid=7GBf3b_q687mmM%3A&vet=1&w=500&h=332&client=opera&bih=967&biw=1880&ved=0ahUKEwij0Jqhg9bWAhVHiFQKHcaVCmEQxiAIGigC&iact=c&ictx=1 the ones on your board are enclosed so I doubt the nail polish trick will work I think you just have to live with it.

Hi. I also thought coils, maybe it was that before but now I think its a new mosfet problem ... My 2080 TI says exactly like this! :

That very strange I never herd a mosfet sound like a coil whine, but I think you mite just have to live with it unless you want to replace it, but that mosfet must be driven hard to make it sound like that, because people are saying on electronic forms that they start whining when they get hot so maybe a heat sink will help.
