Hi there.

I have an XFX R9 390x in my pc which is emiting a whiny noise when I game. The noise is there briefly when i start up and then in games. If I tab out of the game the noise disappears. Its not jet engine loud but its constant and gets annoying after a short while.

I disconnected each of my case fans one by one to double check that they were not the source of the issue. I also took the side off the case, while in a game, and had a listen. While it is hard to be 100% sure , I was 99% sure it was the gpu causing the issue.
I RMA'd the card and put in a replacement card. This card did not have the issue initially but it developed within an hour or so's use.

I was going to add noise dampening foam to my case, Phanteks Enthoo luxe, the kit from overclockers which is cut to size. https://www.overclockers.co.uk/ocuk-tech-labs-noise-dampening-kit-phanteks-enthoo-luxe-cm-240-tl.html

Not sure if this is a waste of time or a good idea.

Would it be fair to say that it unlikely that both cards had the same issue and after some reading it appears the psu could be causing the gpu to whine. Is that correct?

I tried under watting the GPU in the AMD software and this seems to remove the issue but I dont know if this will adversely impact the card. If I limit the FPS to 40 or so there is no noise. Normally the FPS is capped at 120. My monitor is rated up to 144 but I didnt see any difference in Warcraft between 120 and 144.

PSU is a EVGA SuperNOVA 750W PC Power Supply - Gold. I should be well within the wattage required for my system with one GPU and an I5 4690k OC'd to 4.3 using 1.3v.

3 case fans
CD drive
SSD
HDD
No other items drawing power.
Could it be a slightly defective PSU causing this issue?

Any thoughts on how to fix this issue? Happy enough with the card otherwise, temps are high but my new case and better airflow has left me with high 80's while gaming.

Most people don't realize that their PSU typically causes the coil whine in the GPU or is in fact the source of the coil whine itself. But you seem to be informed enough. Best bet is to try another if you have one available.
It's considered "normal" my first xfx r9 390 had the same problem but it was jet engine loud and they replaced it with a new one, this one is barely audible but the whine is there when u start hitting 60+ fps. There is no fix, however if the volume of the whine is high you Will get an RMA 99%. Mechanicaly it's nothing to worry about the gpu Will function as good and as long as it should it's exclusively an annoyance issue. Hope that answers everything.

I have an XFX Pro 750w and i tested the gpu in a friend's PC before the RMA with the same results but it's definitely a good idea to test it in another pc/with another psu yes.
 
I dont have access to a spare PSU at the moment. I was considering dropping the OC on the CPU for the moment to see if that impacts it.
Its a good quality PSU from Tier 1 of the PSU list so it should not have an issue, unless it got a knock somewhere along the way.

Are there any of the other 390X's that are less likely to have coil whine? I see the Fury and Fury nano's are dropping price to be not much more than a 390X.
Worth getting one of them? Would likely be overkill but would be nice to run my games on max. Fallout 4 struggles at times with my current card.
 
I am running at 1440p with a 144hz Freesync monitor. Its probably pushing the GPU but it should be well within its limits to deliver that in alot of games if not on Ultra then on high.
