That is a bit too high, but not "TURN IT OFF NOW OR IT WILL CATCH FIRE" high. You definitely want to look into more case fans and or a better heatsink, also clean out dust if it's dusty, reroute cables, zip-ties are your friend here. I assume that is under maximum load, and max load playing BF4 will give you the same temperatures as max load rendering, so just do what you can to minimize heat.
