I have a Radeon X1950 card in my Dell Dimension 9150. When I bought the computer I upgraded the graphics card from what came standard with it to the Radeon X1950. On all new games (UT 2004, The Witcher, Bioshock) I am getting a message about five minutes into the game saying that my graphics card is overheating and it says it will automatically scale back the clock speed to cool it. Question 1: Should I be doing something about the cooling inside my computer? Such as adding more or new fans to the computer or are there any other suggestions? Question 2: Is the card automatically adjusting itself enough? or if I keep playing may there be problems? Thanks for any help you can offer.
