Nzxt manta fan hub

[MvDuke]

Hello and thank you for your time reading this

I just built a new system :

Motherboard: asus viii impact
Gpu: gtx 1070
ram: 16gb ddr4
ssd sandisk ultra II
psu: cooler master v550
case:nzxt manta

All went ok , but i ran to a problem.

I plugged in the fun hub to my motherboard and my cpu's cooler to my motherboard's cpu fan plugin. All my fans except my CPU's ran at a very high rpm even at idle. On my software i can control my cpu fan speed, but not the others. Can you suggest me where do i have to connect my hub properly to control my fan speeds? I read that you can control with this hub 1 fan's rpm and this fan will give signal to the other case fans , so one fan represents the other 2 but seems like i cant control none of the three right now. Did i plugged the cables wrong? I plugged the hub's molex directly to my psu. ( My case has 3 stock fans 1 exhaust and 2 intake).

Is there any solution to this problem?

Again thank you a lot for your time and I'm looking forward for your reply.
Sorry for my bad english

"I plugged in the fun hub to my motherboard"
How many pins does the hub connector have and to what header on the motherboard have you connected it?

The hub has a 4 pin connector, i plugged the cable in the lower right port above 3.1 usb connector. (see picture so you can understand where i mean). Also my cpu cooler is plugged in the upper left "cpu_fan" port

Look at the manual that comes with the NZXT Manta. It says to plug the PWM cable into the CPU_FAN. Connect your CPU Cooler to the Extension Cable coming out of your Manta's Fan Hub. The extension cable is the one to the left of the PWM cable and both should be labeled. You should look at the diagram on the lablel, it is very self explanatory. This is what I did and it works fine. The manual clearly says, "For full PWM support, please connect the PWM cable from the hub to the CPU_FAN port on the motherboard. If no PWM signal is provided, the connected fans will spin at full speed." This is exactly what is happening for you because instead of connecting the PWM cable into CPU_FAN, you plugged your CPU cooler into CPU_FAN. You should plug your CPU cool into the extension cable coming out of the fan hub. Hope this helps.
