511 cpu fan not detected
I have a big problem, my cpu fan no longer works. as of late for the past two years I the fan has made loud humming sounds and sometimes screeching sounds (sounds like two pieces of metal are rubbing together). this happens mostly when i play some sort of media file. I've removed the fan to to check if it was broken or needed replacing but it was fine from what i saw. (it did have alot of dust though) only this morning though i was downloading something and surfing the web when the computer just completely slowed all together for about 5 minutes and then shut down on me. Where there used to be a green light blinking by the power button was now a red light. I think the cpu might of overheat.
The computer is compaq presario and its 5 years old, is this normal for an older computer.
How can i get the fan to work again.
I have a 2 ghz intel processor if that helps. ask if you need any more info

The fan bearings are probably fried so chances of getting it to work are slim and it will just die again.

Look for CPU heatsink/fans at or
Some good ones are Zalman, Thermaltake, and Arctic Cooling
You will need to know your CPU socket type to choose one.

Edit: Of course that doesn't help you today or tomorrow. A 2GHz CPU may run with no heatsink fan if you open the side of the case and aim a fan at it (while you are waiting for a new one).
