Interesting.
I would say 85c is pretty high for a 270X card.
But as said via the other poster, a lot of it does depend on what type of case you have your 270 card in.
If it`s a small form factor, and not a large Atx style case with not many options to fit case fans in things will heat up quickly including the 270 card you have. This can happen from time to time, and just luck of the draw. There will always be a percentage of cards that have very small faults with them such as improper fitting of the cooler or thermal application layer between the cooling solution of the card and the Gpu of the graphics card it`s self. It does happen from time to time.
If you do have space in the case to fit about two or four 120mm fans then you should fit some.
In what we call a push, pull config.
Air being drawn in from the front of the case and air pushed out from the back or the top of your case.
Have a look around for reviews of your model of card you have via google and see what the test results reveal on average with the 270 card running under game testing ect see if the results match or are near the temps you are experiencing with the 270 card you have in your system.
If it worries you and turns out your temps are a bit high then simply send the new card back under warranty and rma procedure and ask for a replacement. in some cases the cooler is not factory fitted well enough so you end up with higher running temps on the card.
