According to an article in the Croatian magazine PC Ekspert, mentioned in the enquirer.net, a simple screensaver can toast a GF FX 5800 Ultra board, causing it to reach temperatures of 95-100 degrees Celsius. nVidia have been made aware of this issue and are working on some solution.
The problem, apparently arises when running full versions of 3D screensavers, which the card does not recognize as 3D utilities therefore causing the cooling fan to stop functioning. According to the staff at PC Ekspert, any 3D screensaver will do even Windows\' own 3D Pipes but a more powerful one is needed if you are in a hurry to get your board hot. As soon as the screensaver launches the fan starts working but 5 to 10 seconds later it stops. Within a few minutes the card will reach 95-100 Celsius, also causing some distortion on the screen.
Croteam, Croatian games developers of Serious Sam fame, also managed to replicate these findings even when using an nVidia reference board they received from nVidia Developer Relations.
