My graphics card fan is going crazy! I need help please!

Recently my graphics card fan has been crazy whenever I try opening a game, when the game is about to load with all the developers and everything my fan gets a little louder then when I am in the actual game it starts going maximum speed and my fps goes from 80-100fps to 20-40fps - Best regards Jonathan
Quick edit: Sometimes it says if I try opening AMD Settings are currently not available. Please try again after connecting AMD Graphics. (says that now)
