Fan Control with a 3-pin Fan

Yesterday, I was looking at 120mm fans for my computer, and I was thinking of buying Noctua's nf-p12. I was hesitant because I am not sure if this fan can be controlled by the motherboard to match the system/component's temperature. From online sources, nf-p12 has a 3-pin header. However, on Newegg, the power connector specification says 3 / 4 pin.

The specification on Newegg led me to thinking that the nf-p12 can be controlled because, from my research and my understanding of it, there are some 3-pin fans that could be controlled by the motherboard through the PWM mechanism such as the Scythe's SlipStream.

Can anyone tell me if the nf-p12 can be controlled or not?

I am looking for a reliable 120mm 4-pin fan (it's for the cpu heatsink) that has a high airflow that is no louder (under normal load) than my power supply (TX750W). So any quick suggestions are welcome.

Thank you in advance for any input you guys provide.

I believe in most BIOS'es there is an option to control fan speed on 3 pin fans. on my asus this is called q-fan. When it's disabled, the fan spins at max rpm. when it's enabled it spins at lower rpm.

I think all it does it change the fan from 5v/7v to 12v

Is the fan speed fixed until the setting is changed, or does the motherboard change the the fan speed based on the temperature?
