Peter, I have an Asus K8S-MX mobo with the same problem. The fan
speed threshold is fixed at 1800RPM. Your Arctic Cooling HSF must be
the temperature controlled version, when first turned on it is
naturally cool and turns slowly, less than 1800. Your only fix is a
new mobo, or new HSF, or turning off the bios warning.

I don't recommend turning off the bios warning because your new HSF
has exposed fan blades that just beg to snag any loose wires you might
have floating around in your case. If you choose to use the fan (and
turn off the warning in the bios) I strongly recommend using some
twine to tie down all the wires in your chassis so that the
possibility of a fan snag does not exist.
