Hey,
I have only one actual PWM fan header on my motherboard, the cpu_fan header. Recently I bought a Be Quiet! Dark Rock Pro 4 and as such it's currently plugged into that header. The other sys_fan headers are voltage controlled and my two noctua industrial PPC fans, which are both 3000rpm PWM fans need to be controlled through PWM. The issue however, is that they can only go down to 40% due to the voltage control. I verified that I can achieve lower speeds when they are connected to the cpu_fan header, however can't have them connected permanently due to the fact they would be speeding up and down as the BIOS controls the header. I was considering buying a PWM fan hub and plugging it into a sys_fan header however, wasn't sure if the PWN fan hub would also have to use the voltage control, thus getting me back to square one.
Thanks in advance,
