Conformal coating on the coils should clear it up.

Depends on the company. Some will, some not. If you want to you need to contact them. And make sure it's not the PSU (something I've found in many machines where people think it's the GPU).

Ive heard hot glue on coil will sometimes also dampen it.
The problem is this.
If they wont RMA for coil whine.
And you do modify it with conformal or gluegun.
And then you do have a real RMA worthy failure it better come off easy or they will jerk you around over modifications.

I had a board once that I put a CPU into which was from another setup i used to go cold with so it had a bit of vaseline on it not much but trace amounts on the edges, and the Mobo failed due to a bios failure it would boot in secondary bios but not flashable and was getting worse.

Asrock Jerked me around because they found a dab of residue from the vasoline on that cpu socket not even in the pins just the corner of the plastic where its keyed because i didnt rub it off my cpu properly before switching it.

The funny thing was it ran for 6 months before issues.

Now that board never even got the vaseline treatment because it was just a gaming machine but it nearly cost me warranty and they argued with me over it for 2 weeks before yielding and i think the only reason they yielded was because the 2ndary bios was working and probably to their dismay tested by their 3rd party dealer before he sent it too them which was documented.

If it had been a full hardware failure likely they would have just laughed at me.

New mobo has been working since no issues with the same CPU although i cleaned it up a bit better this time before intalling it.

I returned a card for coil whine so loud I could hear it at the bottom of the stairs!
There is no way a card touted as being quiet (esp the ones with 0db no fan at idle) should be considered acceptable with coil whine.

conformal coating is certified to protect electronics from all kinds of things. Moisture mainly... it won't harm anything.

That will only work on an open style coil, not the covered ones like on most cards now a days.

Agreed with above. Try RMA. If that doesn't work, try conformal spray but it might not work if coils are covered.
