I have a Cooler Master Hyper 212 EVO on top of an AMD FX-8350 on a Asus Crosshair V Formula-Z, Sometimes when I turn on my computer it says CPU Fan Error, But I turn the system off then turn it back on and it boots right into Windows. What could be a solution if any to this problem. Thanks for your help in advance.

Is the fan plugged into the CPU fan header and not a regular fan header?

Maybe you have a faulty cooler. The wire may be a defected one. I don't know why this would happen. You might want to see if anyone else with this cooler had this issue.

Yes the CPU Fan Is plugged into the CPU Fan header.

The RPM of the Fan is lower then what the option in your BIOS setting can detect.

 

I think the default fan setting on ASUS ROG boards is like 600RPM(?). You can go change it in your BIOS and you won't get system error anymore.

 

You can either lower the detection RPM. Or, you can make your CPU Fan run on a consistent RPM like 1000RPM below 30C, then ramp up as temps get higher.
