Marked in red are the three PWM case fan headers, marked in green (at the top) is the CPU and CPU optional PWM headers.

Marked in purple, also at the top, is the high amperage PWM fan header.

 

These can all be speed controlled through your BIOS.

Let say that my PC case has PCB controller and that i need to connect it to my motherboard PWM. Wish one should i use.

Depends on if you are connecting the CPU cooler's fan(s) to the controller too or not.

If you are connecting all the fans, including the CPU fan to the controller: you connect the encircled connector to the CPU_FAN connector, in green at the top of your board.

If you are connecting all fans, excluding the CPU fan to the controller: you can connect it to any of the red/purple connectors on the motherboard, while the CPU fan(s) is/are connected to the CPU_FAN connector.

 

 

 

A motherboard has a built in fan speed system. If your CPU is x degrees Celcius, run the fans at y speed, which can be changed in the BIOS as to how it should react to certain temperatures.

Basically what this controller does, is take that signal from your motherboard and distribute it to all the fans connected to the hub.

Your motherboard requires something to be connected to the CPU_FAN header, because otherwise it will throw out an error (which in theory can be turned off, but avoiding the issue is just better).

 

Hope my answer was clear, but if not please do reply and tell me what I can explain further!

So my plan is...

I am using a Noctua NH-U12A  that will be connected directly on the MOB. But still undecided if i want to connect both fans on the CPU_FAN connector using a Y adapter, or connecting one fan to the CPU_FAN and the other to the CPU_OPT (who is better).

So i guess i will be connecting only the 3 PC case fans to the HUB. One thing I am not sure is the voltage. If all fans are connected through the HUB to only one connector on the MOB, isn’t there a risk or overloading the MOB?

It wouldn't matter if you use the separate CPU_FAN and CPU_OPT connectors, or if you use a y-splitter for CPU_FAN. 
The only advantage with using both connectors is being able to control the fans separately, but that is not something that most people will do.

No, there is no risk of overloading the mobo.

The reason I say this, is because the fans on the controller are not getting power through the motherboard, they get power from the hub (which gets it power from a SATA power connector from your PSU). The only signal the controller gets from the motherboard is a PWM speed signal, to give to the fans connected to the controller.

 

How I'd personally do it:

- Connect your CPU cooler fans with a Y-splitter to CPU_FAN

- As for the case fans, I'd personally just go for the option which allows for easiest cable management. Or if the fans require the LED connector on the controller, I'd use that.

If you can easily connect the case fans to the headers encircled in red, do that. 

If you need to connect the fans to the LED connectors on the controller and/or if the cables are easier to manage when using the controller; use that.

First, I really want to thank you for the great help you are giving me. This is my first build, and so far it is going well. I just want to make sure that I connect all the wire to the good place.

 

I will be using a Y for my CPU fan connection as you suggested.

All my fans are none LED. So for me it doesn’t really make a difference. But I do have some LED strip that came with the PC case.

So if I understand you correctly, it doesn’t matter of the fan are connected through the HUB or directly on the MOBO, it’s only a matter of looks and cable management I guess.

SORRY about repeating myself, I only speak French, just want to make sure I understand you correctly.

Finaly i have two more connection that i am unsure where to plug them, can you check them all form me.

G is the simplest, it connects to one of the SATA power connectors on your PSU. 

image.png.e52f6240cacc7a13261d5a6e6884c523.png

The look will vary, but your PSU will usually come with a cable either attached, or loose (if it's modular) that looks a bit like this, with a bunch of wide connectors on them, SATA power connectors.

Plug in one of the sides into your PSU (assuming it's modular) and connector one of the leads to the controller. (possibly using a cable that came with the case).

 

Connector C is to connect to the RGB header of your motherboard, but there are multiple types of RGB connectors out there.

What case do you have?

For SATA, you are saying that i can use the same SATA for connecting my HDD

Yep, exactly one of those.

As for the RGB stuff, I am not 100% sure where it (C) should connect to. There are +12V RGB LED connector on the motherboard, but I am not 100% sure f those are the right variety for the controller on the case.
