Asus Maximus IX Code CPU Speed Fan Error

Good night!! I have recently bought this new MOBO z270 with an i5 7600k... I have installed a Corsair h80i.
Well the problem I have is when I turn on the PC, shows me "CPU Speed Fan Error" on the boot.
So I enter on the BIOS and check the fan speed and show 800 rpm, I ve select "Ignore" on the Fan config to avoid the speed fan and the save and restart the computer but I have the same error.
I was able to enter on Windows from Boots option and selected the Windows storage. On the AI Suite shows 0 rpm of CPU FAN.
I have tryied a lot of things, connected on other fans pins, update the Bios and does not work.
I don't know what it is.






Thanks for your help.
