Dell 3000 case fan running 100%?
I'm working on a Dell Dimension 3000 desktop. It had some spyware and viruses in it, which I fixed. I did the Ctrl-F11 PC-Restore thing and got it cleaned out, and got all the usual updates from Microsoft, etc.
Only one weird thing. The case fan screams all the time now, running at 100%. Once in a while it slows down, but most of the time it's running at full power and making noise like crazy because of it.
Why? I didn't do anything fancy or tricky to the computer, just the usual overhaul like I've done many times, although this is my first time using the Ctrl-F11 PC Restore function.
Task Manager shows nothing unusual, even with the CPU at 0%-2% usage the case fan is still wailing away.
Any ideas here?

Taking the side cover off makes the fan speed drop somewhat and get quieter, but putting the cover back on brings it back up. I didn't see any switches that indicate when the side cover is removed.
The case fan is designed with that curved green plastic cover that pulls air over the CPU on its way out of the case.
have anyof your othercase fans stopped working? or are they clogged?
give it all a good clean and check for the operation of the case fans... if no luck, look in the biosm if no luck there check the fan connector.
