Re: [CGUYS] Computer fan
The bearing is going out on one of them... one of the two moving part physical failings of computers. Short of unplugging one or the other, as Tom says, stick a plastic fork in one of them for a moment and you will know which one it is. Then replace it... db Robert wrote: I have a Dell XPS desktop PC that is about 4 or 5 years old.

Re: [CGUYS] Computer fan
Have you done a good job of removing accumulated dust? Dust acts as an insulator, and components covered with dust will heat up to a higher temperature, thereby causing thermostatic fans to speed up.

[CGUYS] Computer fan
I have a Dell XPS desktop PC that is about 4 or 5 years old. I believe in keeping the computer running all the time (because this household computer has multiple user profiles, is used frequently, and takes about 10 minutes to boot up in Windows XP Home).
