CPU Fan Error

post #1 of 7
Thread Starter 
I have just built my new PC and booted without any beep, however I have one problem.

I always get the "CPU Fan Error!" message on screen at every boot. I have to load the BIOS and exit out just to run the Windows environment.

No, no. Hang on! My CPU fan (Noctua D-14) is actually spinning just fine. When I was installing the fan, the fan connector has 3 pins, whereas the CPU_FAN socket has 4 pins. So, I connected the fan connector with PWR_FAN because that socket has 3 pins.

So, how do I get rid of the CPU fan error? I've checked through the BIOS to disable the check, but nothing.

Thanks in advance.

DOnt worry, the Mobo is set to make sure you have a fan on your CPU heatsink! if you have nothing plugged into the CPU_FAN header you get that error message you are seeing. WHat Mobo do you have? EG - on mine you can toggle the fan checking to

Having said that, Slectstriker2 is correct - you can still plug a 3pin fan into a 4 pin CPU_FAN header as the guide on the CPU_FAN header should still accept the 3 pin fan connector.
Its up to you!

Setting CPU FAN to N/A will ignore this header

If you don't use the 4 pin header at all, you can disable that error in Bios.

Thanks, I guess I'll move the fan connector to CPU_FAN later.

regarding the BIOS, I did change the fan features but that didn't get rid of the message. my motherboard is asus P8P6 pro

oh hmm, you said ignore. I did the "disable" one, I'll try ignore

Not really, disable only stops the fan control rather than fan checking.
