I have an Asus Sabertooth z87 motherboard and a noctua nh14s cpu fan. When I boot up the computer, the "American Megatrends screen comes up and tells me that there is a "CPU FAN ERROR". If I got to the bios, the cpu fan is spinning at about ~530 rpm even though the absolute minimun is set to 600. If I try to adjust the speed, nothing happens.
Cannot control cpu fan from motherboard BIOS

You may need to update the BIOS.It should fix things.
Update: Before updating the BIOS,you could try to reduce the CPU fan speed further....Like 400 rpm or 300 rpm,(or even 200 to see if it'd boot),save the BIOS and exit.I saw in a thread that this should do the trick...Give it a try before updating the BIOS...

This was said by one of the experts:
"So you did reduce the cpu fan from 600 minimum to 400 minimum correct and did you try 200 or even 0 to see if it would boot? Since you know the CPU is spinning try this and see what happens. I also assume you are on air and not water-cooled. I just built the ASUS Maximus VI Formula last month and the ASUS ROG website recommended this and it did work. '.
So it should be fine,try it.
And another thing you could try is, just set the CPU fan speed monitoring to "ignore" and mobo will not check the fan speed while booting which will prevent the CPU fan error
