Not that I know of but it stays at 67 degrees usually and 65-70% fan and its just crazy loud - I NEVER had this problem with it in my old computer so it's just a new thing it's acquired.
67 degrees is fine, I wouldn't bother about changing the thermal paste then.
65-70 percent fan speed seems okay as well, however it should not sound that loud to the point where it is bothering you.
Maybe you need to replace the fans? The bearings could be no good which can produce unnecessary sound.
I think it just bothers me the most because any other game I play it doesn't do this but as soon as I launch FN it gets loud. It's an old card I've literally had for years now so I'm sure things are starting to go on it.
It could possible be an issue with Fortnite and the R9 270x if it only triggers in that game.
I don't have fortnite installed on my PC so I cannot test if my R9 270x will do the same thing.
