CPU fan Dimension E521

There are too possibilities:

1. The CPU is heating up and the CPU is cranking up to cool it. Possibly the case temps have gone with the addition of the new equipment, making it harder to cool the CPU.

2. The CPU fan controller is broken. The CPU is not overheating, but the system thinks it is and revving up the fan.

I suspect 1 over 2. You should be able to test the fan and controller in the Dell diagnostics (you can for Intel based Dells). To test if 1 is the problem, you can open the case and point a desk fan into the system. If the CPU fan slows down, then you know the case temps are too high.

If the error message reads, something like this,

'Alert! Previous Fan Failure. Strike the F1 key to continue, F2 to run the setup utility'

Try this first,

1. Restart the system now and press the F2 key as the Blue Dell logo appears.
2. After that the system setup screen will appear, on that screen, go to the "Maintenance" option and then press enter.
3. Under that there is one option for the "Event Log". Select that and press enter. Then select the option “Clear Log”.
4. After that select the option “load defaults”, select the option “Continue”.
5. After that press the "ESC" button from the keyboard and select the option that says "SAVE/EXIT".

If the above does not correct the problem, replace the fan unit, system under warranty contact Dell for a replacement, no warranty, then you need to buy the replacement from Dell, because it's a proprietary unit.

1. the CPU isn't too hot, the heatsink is icecold and Speedfan detects 18! °C 2. i tried to solve the f1 error like this before, but the problem is still present so I will try the diagnostics thing... Thanks for your help!

In diagnostics the fan is working properly, first it gets louder(2500 RPM) and then it get quiet(900 RPM), but after the test it goes on with 2000 or so...

So what could be the problem?
