3pin, 4pin, PWM, Voltage Control?

Hi,

Firs of all I'm sorry if this was answered before but I can't find the clear answer for my question.

I'm planing to join the ROG family once the M6Impact becomes available and wanted to make sure what kind of fan speed regulation are the ROG boards capable of using for chassis fan headers. I know for that Asus uses new connector on the CPU Fan header to detect what kind of fan is connected but all the other 4-pin fan headers on the motherboard are just standard fan headers.

The only way to control both 3pin and 4pin fans (and I know they are capable of controlling both) without any detection is to use voltage regulation or have menu item to set the type of the fan. I didn't saw any 'fan type' setting on the UEFI screenshots for ROG boards and also didn't saw option like this in UEFI of my current ASUS board (P8H77-I).

So my question is:
Are the chassis fan headers on new ROG boards capable of controlling fans using PWM (and if so how you set them in PWM mode) or are they always voltage controlled.

The answer to this question will influence my choice of fans for my next build so I hope someone will be able to answer it 🙂
Thanks.

Haha, well that all kicked off. I think it's been cleared up.. but I certainly haven't tried to power my PWM DDC pump using a fan header.. I'm no fool. the fan header simply provides the RPM control via the PWM function. My pump is indeed connected correctly via molex. My point stands.. 4-PIN hears are PWM headers as non PWM 4-pin should simply be 3-pin headers.. and so it should be clearly documented. But nevermind, the DDC pump isnt loud at 4000rpm so I'm over it.
