Citace:
The X1800 XL also comes with dual dual-link DVI, but it is in a single-slot solution. The heat sink is made of copper so the video card is heavy. The fan, however, is very small. In operation, there are two fan speeds, a slower speed, which is not very loud, and a higher speed, which is very loud. In fact, the fan speeds up and speeds down between these two speeds frequently, even when the card is in idle 2D mode. What this means is that, even at idle, the GPU is getting hot enough to cause the fan to spin up to higher speeds to cool it down. It shouldn’t come as a surprise then that this video card gets very hot during a full load situation such as gaming.
