Fan Error on boot up

[86d]

I recently changed my stock case to a Cooler master HAF.
Since then I am getting a Fan error message in the boot up. I checked the bios, I can't locate the turn of fan monitoring in it. I have an asus motherboard from a HP computer.

There should be a disable fan warning some where in your bios..
