CPU Quiet Fan on AliveNF4G

I'm thinking of building a system with this MB using the retail fan.
In the user manual the CPU fan header has 4 pins
GND, +12v, CPU_FAN_SPEED and FAN_SPEED_CONTROL.
My memory of the retail fans (supplied with CPU by AMD) is that they
are 3 pin.

Am I unable to use the bios enabled CPU Quiet Fan with this MB &
retail fan ?

Thanks

Just to tidy this thread up.
I got a response from ASROCK about this.

They say you cannot control the speed the AMD supplied fan with this
MB.
It needs to be a fan with a 4 pin connector.
