Ok, so I was playing XCOM: Enemy Unknown, and started to notice that the heat from the card (by placing hand behind system) was rather high. So I started to take a look, and it said it was around 60°C.. Is this temperature too high? Also, the case I'm using is rather small, but I always clean my system from dust. I was playing for about 3-4 hrs. Perhaps I played too long? The settings ingame are medium and low now, they were all set to high earlier.
