My HP Pavilion 21020n has given me an error message stating my system fan failed, where can I find the system fan?

Start your notebook and start tapping the F2 key. In the diagnostic screen perform the hard disk diagnostic. If the diagnostic reports a hard disk smart test fail, then your hard disk is failing and must be replaced. That is the only way you will be able to return your notebook to useable condition.
If hard disk is ok I suggest you goto HP support Forums at

Did you try;

Power off, power unplugged to computer.
Press the Power On button, and hold it in. Hold for a count of 10 seconds.
Let go.

Do this procedure two more times.

Plug the computer back into power. WAIT 1 minute, turn the computer on.

This method clears CMOS Error Codes, and sets BIOS Setup back to the factory default settings.

CPU fan spinning at required minimum RPM's?

Not talking about the SYS_FAN (Case fan)

1. Check if fan is spinning. If not, replace with new one or check cables.
2. Check if there are no swapped fan connectors when reconnecting mb cables.
3. Check BIOS update on HP website. Choose your OS here: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&dlc=en&cc=us&lang=en&product=3339287&
4. Check for a BIOS setting for disabling the fan monitoring.
5. Install a monitoring app which reports fan speeds and temps. See http://www.cpuid.com/softwares/hwmonitor.html
6. Check if CPU fan works.

Does the fan spin up? There is a third wire on the fan that is interogated by the uProcessor to determin how fast it is spinning. If it is spinning but not registering, there is an interface problem, maybe poor connecion on the socket it plugs into?
Hope this helps.

Your system's fan has failed. If it is under warranty, you need to have HP made aware of this failure.

Yes that is what you need to do. It's either due to your CPU board having issues or your fan is just old and needs to be replaced. You always need to have a fan running to cool off your CPU. Let me know if this helps and if you need anything else.

POST troubleshooting steps. If a fan has failed (especially the heat sink fan for the CPU)

Good Luck, Please dont for get to Vote.Thank you.
