Just bought Sspphire R7 260X rattle noise when fan ramps up?

I been holding off buying a graphics card for years, my last card was a passive cooled 3850 Ultimate so I know "anything" will be an upgrade at this point.
That said I bought the Sapphire R7 260X from Newegg...PC has been up for 48 hours now since install I'm noticing when I put the computer to sleep and or cold boot when the fan ramps up there is some kind of vibration and/or rattle noise, it's very brief and only when it's ramping up. Other then that at idle it's quiet, I haven't put too huge of a load on it so not sure exactly how loud it will get.

I'm not sure if I'm just worrying about nothing, as I've never really heard a fan make noises when they speed up from a reduced RPM. So I'm wondering if I should bother RMA'ing it for another one, RMA for something completely different (but what else is in this price range and decent, under $120) Or just keep what I got and see how it works before the 30 day return period expires.

Thanks in advance for any help/suggestion

Top of mind answer: See if there's a wire touching the fan shroud.

Thanks for the reply, I looked around I can't see anything to cause the issue other then the fan it's self, with ear closer it sounds more like a grunting noise as the fan ramps up. It didn't start doing it till today, with about 30 hours on it, just called Newegg and set up an RMA see what another one does. This reminds me why I went passive in the first place, but I would like to play a few more current games.
