How to control the speed of Noctua NH-D14 in asus p8z77-v motherboard ?

[loginuser]

I know that Noctua NH-D14 comes with two fans that have only 3 pins, whereas the asus p8z77-v motherboard cpu fan can only be controller using PWM. so I guess the Noctua fan will always run 100% in this case.
Is there any method that I can use to avoid having the cpu fan running at full speed all the time? (without replacing the Noctua fans ofcourse)
Thanks.

Using a Chassis fan header (not recommended) and disabling in BIOS the warning or a fan controller.

the chassis fan header have 4 pins, so is it possible to control the noctua fan using this header even if it's 4 pins ? if yes, then how come the cpu_fan header with 4-pins can't control the noctua fan, whereas the chassis fan header can ?
I know that cpu_fan header on asus p8z77-v can't control the cpu_fan speed using voltage, it only does with pwm, is this the same for the chassis fan header or does it behave diffrently ?

Thank you for replying.

For the chassis fans is different. Have you tested?

no I didn't buy the noctua yet, I just want to make sure I can control it's speed using one of the chassis fan header before I purchase it. So I will be able to control the fan speed by changing the voltage or what ?

I see that the fans are PWM for this model.
Isn't it a better option?

as you can see from it's name, it's only compatible with lga2011, I have lga1155 socket mobo. I guess I will just leave it full speed all the time if I can't control it's speed, thanks for your suggestions.

Right, I haven't checked that.
As an option, you can install PWM fans though with the D14:
