Many things,
First,if your game can't get more than 60 fps or is locked at certain FPS,leave it at that FPS,set it to either 60 or 90 as most games support only these
Second,Always use level 3,with hardcore tuning and everything on red aka max,to achieve way more frames
Third,that kind of heat is normal,room temperature and climate affects it's system temperature,but don't worry about it,it will not do any damage whatsoever
And lastly,expect more heat with higher frames,it's normal
But if you can't handle the heat,turn everything on 60 fps and you'll be ok
