Not sure what the issue is, however, I noticed that the fan on my new GTX 275 would Stop in the middle of an intense game or when it reaches a temperature over 95C. Obviously this leads to it getting over heated. This seems to happen whenever I have the automatic fan settings enabled in Nvidia's Ntune Utilities. I have since manually set the fan at 80 - 90 percent whenever I start playing any games and that seems to help prevent the fan from stopping. Is this normal? has anyone else had this problem?
