I recently swapped the graphics cards between my two computers, a Dell XPS 630i and a Studio XPS 635mt. I placed a newer Nvidia 9800 gt from the 630i into the 635mt and placed a ATI Radeon HD 4350 into the 630i. I use my 635mt for gaming mainly. At high settings while playing Crysis i can get temperature readings from Rivatuner as high as 92-98 C with the fan set to max speed and the side case pulled off. Is the temperature too high and should I invest in a cooler?
