Cpu fan error

What is the error message? Check the BIOS. Look under "PC Health Status" and then look at the details on the CPU_fan. If the settings are ok, then take a look at the fan attached to the heatsink for mechanical/electrical issues.

I had the message too, my cpu fan was running to low. I changed the min speed in the bios.

You may have to set the bios to ignore the CPU fan speed.
Related to CPU Q-Fan control also if enabled.
You still have control via temperature of the CPU.

Page 3-23 and 3-24 of the manual.

thanks

plug something into the cpu fan header or turn it off in the bios..choose to ignore the message if u do have a cooler! However...be cautious..if ever something happens and u dont have the warning u wont know whats wrong with it
