ATI X1900gt overheating problem

[sparky79]

I recently built a computer for the living room, I took the graphics card out of my main computer and put it in the new one. Well at idle it used to run at about 47C, and in the new computer it runs at 61C. This tower has 6 fans and plenty of airflow, but when i start a game, (why I built it to game on a new LCD) the card reaches about 120c and shuts down. What can I do to fix this? I already cleaned the card and applied new thermal grease and that saved me about 3C, but still the problem. Help please.

The case I am using is a Coolermaster Centurion. Actually the thing that has me stumped is that the room it is in now is always cooler then the room i had it before. It averages about 71f. With a thermometer the inside of the tower, with the panel closed, is about 80.3f and the cpu runs about 93f (pd 915 at the heatsink), and the GPU is at 165f at the heatsink. Could this card just be bad needing a new fan, by the way, the fan is running at 100%.
