Need help..... my internal PC fan is extremely noisy

I have a Dell PC..... an Optiplex GX280.

When i first turn it on the fan is audible, but not terrible.

However, when I try to run anything the fan will kick into maximum overdrive. It sounds like a damn jet plane takeoff. It sounds like it is spinning extremely fast and it is also extremely loud.

Is there something I can do about this? Can I change the settings so that it will not spin so fast? Also, can I do something to make it less noisy? Is there some way to lubricate these things?

  1. OEM machines like that are very proprietary. Its difficult to know what the problem is. If you familiarize yourself with your system and pass on some info and the cause of the noise, that would be very helpfull.
