|It's probably very clear that the card Nvidia will introduce tomorrow, the GeForce 9800 GX2, with its two G92 chips, will get pretty hot. The board design of the 9800 GX2 has the two 65nm chips facing each other and although they will be separated by the fan-equipped heatsink, it is safe to say that it will see them reach some high temperatures, depending on the installation setup, of course.
In addition to designing a pretty intricate cooling system, Nvidia has also put in a 'safety threshold' for the two G92 chips on the 9800 GX2. As detailed by the Green Goblin, the GPUs are able to work 'normally', at their stock clock of 600 MHz until reaching 105 degrees Celsius while, it the temperature is exceeded, the frequency will be lowered. While it's rather unlikely that the chips will surpass 105 degrees in a decently-ventilated case, the overclocked versions of the 9800 GX2, like the one 'apparently' prepared by MSI, might run into this temp problem more easily. We'll just have two 9800 GTS cards please.
