Hi guys. I've noticed within the last week that my AsRock Fatal1ty Z170 Gaming K6 makes an almost hard-drive like sound or a coil buzz kind of noise when under load. I.E, if I play WoW I can notice it pretty easily if I get close to my PC, or if I'm allocating space or downloading a game on Steam I can hear it pretty good as it allocates and whatnot. This is the noise in question with my same board:

I know without a shadow of a doubt that it is coming from my motherboard. I only have SSD in there, GPU does not make noise when idle, I've isolated each fan and the noise was not present from either, and have ran the psu outside of my system with no sounds from it.
I also run my system plugged into a UPS so there should be no chance of possibly getting dirty power at all.

I use
MSI GTX 970 Gaming 4G
I7-6700k 4.0ghz non-OC
AsRock Fatal1ty Z170 Gaming k6
EVGA SuperNOVA 650w P2
To list the major parts.

Apparently on the AsRock forums some others have reported having this particular sound but I want to be sure as nothing was truly conclusive and even asrock said RMA was possible for this issue. Is this normal? Any and all responses are greatly appreciated. Thanks!
 
"Is this normal?"
No...
My motherboard ASROCK Fatal1ty Z170 Gaming K4/D3

No sound...
On the other hand my whole system is kinda noisy due to the amount of airflow i've got going on...

Also, If a manufacturer says they will RMA for this... Then do it, because they are acknowledging the issue which means they are aware and it could potentially be/become a bigger issue... Motherboards aren't designed to make sound which could mean there's an electrical issue or that the user has overclocked..

Well that sucks because it literally can't be RMA'd. The PC I have is a prebuilt from MicroCenter so it's either the ENTIRE thing goes back for ?? amount of time, or I live with it. And they also won't replace a part unless it doesn't function, and I don't think a whine/VRM noise is going to fit the bill for replacing it.
