I just adjusted my fan curves and have been playing Battlefront for about 10 mins and now my max temp is 83C so it definately made a difference. Thanks for that, I did have it set before but forgot to do it the other week when I did a reinstall of Windows 10
I was thinking about changing the stock thermal paste but MSI have got a warranty sticker over one of the screws so I don't want to void my warranty yet as the card is only a few months old.
