It means the 3 pins for that fan are not working on motherboard . I suggest you use the motherboard 3 pins for the chasis fan and buy a CPU fan with 4 pin setting that connects to your power supply ( much better current )

I had the same problem out of the blue. One day I tried to power up and I got the same error. I don't know if this is a fix, but all you need to do is press F1 and you are on your way. My fan is working fine!!

Is my cmo s battery goin bad?because every time i start my computer the time is always reset, and also detect error cpu fan.


Yes. If the time is off, the CR2032 battery is probably bad. The battery is located near the PCI port. CPU fan error, is a different issue though. The fan may need replacement. Verify the fan is running and not full of dirt.

When I turn on the power, the fans start to turn but then quit after a couple seconds.


hi,

i,d suggest CPU/Memory or motherboard Fault.
try removing 1 stick of memory, then re-boot. ( if theres 2 In )
remove the cpu fan, Check for Dust Blockage, remove CPU. And re-seat-seal-replace Fan. ( re-boot )
remove power from Case ( mains power ) remove side panel, locate CMOS Battery ( Silver coin-Cell ) On motherboard for 10 Seconds, then replace, repower and boot up.

Any of these could resolve your problems.

Your CPU may have a problem


Have you removed all memory, other cards and unhooked all other drives to see if a short exists there? With a 300W PS some other component may be pulling too much that the CPU can't start so it tells you the problem is with the CPU or The CPU its refering to is on the video card? Good Luck, Tim
