SOLVED Asus Maximus 4 extreme z68 vio crash

[ASUS ROG]

Just update my Maximus 4 extreme z68 mobo bios today to the latest version today, and when i turn on the pc, it will not boot in to window, i got a American Medatrent screen can it say: CPU fan error, please PRESS F1 to enter setup.
I don't know what happen here, is this a bad bios update or what?

Is the CPU fan plugged in?

I have a water block on top of it, it my back up pc, custom loop
Another thing is it will not save my setting too, i try to oc it to 4.2ghz and it not working.

American Megatrends is what it says there (the bios maker).

I believe you should have an option in that bios to disable that fan header or something along those lines. Look through your bios.

The option is called "Set CPU Fan Speed", which should be set to Ignore.

 

[ATMINSIDE]

Yeah, that's why you're getting a CPU Fan error, since there isn't one.

Do what Redduc said.
