So I had my 6600 GT for a while playing games on full res with no problem. Until I got Age of Empires III. This game has so many shaders and polygons but my graphic card can still handle them. Exept one thing: HEAT. It heats up in 20-25 minutes and the game just freeezes. I tried addiing more fans to the graphic card and throughout the case, and my CPU satys cool. I just don't know how to cool down my graphic card. Any thoughts and support much appreciated.
