Sapphire Rx 470 Nitro+ 4gb peculiar sounds

I got three RX 470 Nitro 4gb and one 470 reference (Platinum).
Out of three Nitro+, two had terribly balanced fans that wiggle when they rotate at a low speed.
After two weeks of use, both cards started producing weird little screeching or grinding sounds.
I am afraid that it will get worse (so far hashing is generally Ok, but invalids 5-7%), so getting ready to RMA them.
Third Nitro+ card and reference-just a sound of fan moving air (normal).
So, 2/3 to return-quite bad, actually, despite the fact that card looks good.
Please share if you got something like this.

Apparently, I am not the first one to report this.
