8400 and 8600 很不好，Not 8200

It has been announced by nVidia that some of their graphics chips have a higher than expected rate of failure due to overheating when used in particular notebook configurations. Some major laptop manufacturers are making adjustments to fan setting and firmware updates to help delay the occurrence of any potential GPU failure. In late July 2008, Dell released a set of BIOS updates that made the laptop fans spin more frequently[37]. As of mid-August, nVidia is yet to give further details publicly, though it has been heavily rumored that all or most of the 8400 and 8600 cards have this issue.
