Anyone know why the Xbox One X has this annoying coil noise when playing games?  It doesn't do it if your in the Home screen though.   Is there a way to fix it or to make it a little less noisy?  I should note that it does this even when playing a game from my hard drive...no disc in the system.

Cheers.

I’m assuming as with high end graphics cards it’s most likely a production tolerance/error and not a feature. I’d return it and get another one. This stuff can get really annoying.

Other option is it’s the cooling system. Do others have similar experiences?

I look forward to reading the posts in this thread.

It is probably just coil whine.

Well after doing some digging, it is apparently normal. Bit of a disappointment but the thing is a beast. I played Halo 3 on it today and it looks unbelievable, so beautiful. I'll live with it hehe.

Well, that is...unfortunate. For real?!

I recently got the Xbox 1 X and was rather surprised by how heavy the thing is (as in super-dense). I haven't noticed much noise but I have to imagine it's quite a challenge to dissipate the heat from this thing given how tightly packed it is and that it must be really pushing the graphics card to its limit in some of these games.

I'm not sure something like this could be made without noise... perhaps water cooled, but I don't see that happening for consoles anytime soon lol

Coil whine doesn't have anything to do with cooling though. It's more about power and electricity running through the coil at high workloads.

Here's some explanation by Linus

Sorry, I was assuming it was some sort of heat sink.

Jayward...just because some or even many people have it, doesn't mean it's normal and present on all consoles. If you still have the possibility to swap it, at least try it. I know the situation from some PC graphics cards, but it's also true some models are particularly known for it. I just don't want to believe it's "normal" as you put it. 

No need to apologise...it's not something commonly known among console users. It usually is more of a PC thing.
It's sadly not one single high pitched tone but a whirling tone that constantly changes at different workloads. It can get really annoying because of that. It doesn't blend in the general noise level. I returned a graphics card once and bought one from another manufacturer with a different board design (GTX 970). 

It's not that bad really. At least now I understand why it's doing it. Don't feel like going through the trouble of swapping the unit and have the next one do the same. Too time consuming for me really. On youtube, some have had units quiet for several days then the noise started. Many have said it to be a normal condition.

Johnw1104. I was also surprised at how heavy the system is.

Thank you everyone for your inputs.  Much appreciated.
