Question about HP Pavilion a1720n PC Desktop
Was getting ERROR:System fan failed...F2 to continue because my PC had no case fan. Installed new case fan and it does work. BIOS reading system fan 425 rpm. Connected to mobo with 3 pin. Still getting error message when booting.
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.
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)

That is correct. Also, while you are inside the Pc check the connection to make sure it is tight. If the inside case is dusty, blow it out with a can of compressed air from wal mart. Most modern motherboards have sensors built in and software that monitors temperatures of your hard drive(s), CPU's, Inside case, and even video cards. It's nice to know that the software notified you as it was suppose too. Oh by the way, nice system! Hope this helped.

hello.. this means that the fan which cools your pc is not working, get a new fan for your mode and fit yourself if possible or go to computer technician.
do not keep it using as your pc may crash.
its very important to keep the cpu cool to keep computer working. hope this help.

It is a 2 lead wire (red/white and black) that connect right next to the memory slot. you have to connect the red/white wire to the 5v+ side of the 4 pin peripheral and the black lead to the com (black) on the same 4 pin peripheral. i can't really think of any way better to explain at the moment. but any questions. email @ firstname.lastname@example.org

Go into the BIOS and disable the error message. You will need to look around in the BIOS to find the exact location of the enable/disable setting for case intrusion.

SOURCE: system fan has failed
When the system fan or cpu fan fails you will get this message, or sometimes the computer will actually start, but then shut itself down. The only way to fix this problem is to replace the failed or failing fan. If you don't know how to replace a fan inside a computer, then I highly reccomend that you hire someone to replace it, or get a friend who knows what they are doing, to replace it.
