I got some questions

I recently got a new Enthoo Evolv atx (Tempered Glass).
I saw it had a included PWM hub, and i have no idea if i should use the hub and what it's actual exact purpose is. I use only the case fans and my cpu cooler of course (Noctua dh d15).
Also i got a LNA (Low noise adapter) and a Y-cable. I have been looking around and people have been saying to connect the pwm hub to cpu_fan1 and the cpufans to cpu_fan2 and then the hub would regulate the fan speeds or something. Now i dont know if i should use the Y-cable to connect both fans to only cpu_fan2 or if i should connect 1 fan to cpu_fan2 and the other fan to cpu_fan3. And also if i should use the LNA's, if they have any effect on the performance and if there is a reason not to use them.

As u can see im quite a noobie in this pc building and this is my first build so dont judge,

Thanks in advance

Ok you should see 6 fan headers in total. Leave the CN out of the wording and only look at FAN1 through to FAN6. You can connect your CPU cooler fans on FAN 1 and 2. CPU FAN is for the cable that should run from your motherboard CPU_FAN1 header to the fan hub's CPU FAN.
Read through your manual, page 27, connect the 4 pin header to the CPU_FAN and have the two fans of the cooler on Fan1 and Fan2 while you can have the other fans on the remaining headers. You will not need a splitter since the PWM only sends 12v of power through to the 2 pin out of a 3 pin fan header(which will mean they're running at full blast).

Is it possible to pass on your full system's specs and the number of fans you're working with?
 

Yep here it is:
I5 6600k
Evolv atx Tempered glass
Noctua dh15
2tb seagate barracuda
850 evo 500gb ssd samsung
MSI Gaming pro carbon
Vengeance LPX 3200 mhz 16gb (2x8)
RM650x Corsair
GTX 1070 gaming x msi


By Fan1 and Fan2 you mean sysfan1 and sysfan2 or cpufan2 and cpufan 3 (since pwm goes on cpufan1).
Oh and can you clearify why i should use a PWM hub in the first place? I have seen some comments that you should only use it if u have lots of fans

 
I didn't know what your motherboard was when I posted my first response. I was referring to the PWM hub since it seemed like you wanted to utilize that resource. Do you want to use the hub in tandem with your fans or would you like to use only your motherboard headers?

In an ideal situation where you have all PWM fans(case and cooler),the fan hub connected to the CPU_FAN header will mean that all your fans will ramp up and sway down upon the temperature of your CPU i.e during varying load scenarios. Some would like to manage their fans and the cab;es better thus another reason to go for the hub and the last reason would be to simply use it since it came bundled with the case.

* You use a PWM fan hub with PWM fans only. If you have 3 pin fans running off a PWM fan hub, they're going to be running on ful blast:

What exactly do u mean by this?

I think i'll go with the hub, so from what i understand i will plug the hub into cpufan1 and then 2 CPU Cooler Fans into SYSFAN1 and SYSFAN2, and the remaining 3 fans included in the case will go where?? Since there are 3 SYSFAN slots and 2 are already occupied

Im sorry if im annoying you with stupid questions,i dont really know all the terms for those kind of stuff

 

Yes ofcourse, Left cable is the 12V cable (no idea what its purpose is). 3 connected cables are the fans, and the right cable is the hub connector or however its called, that one goes onto the CPUFAN1 on the motherboard

 
Left cable is the 12V cable (no idea what its purpose is)
That delivers power to the fan hub which means you can connect a wide range of fans to the hub as opposed to using a small range of fans when using only the motherboard's fan header.

3 connected cables are the fans
Correct

that one goes onto the CPUFAN1 on the motherboard

Correct.

Now the fan hub should have some writing on it...can you see them?

Wait so you mean, i connect the 2 cpu cooler fans not to the mobo but to the fan hub? And the other 3 case fans also to the fan hub? That kinda makes sense now. So let me clear this up, the mobo will only be using CPUFAN1, thats occupied by that CPU FAN of the PWM hub. All the other fans go into the fan hub and thats it?
 

Ok so this is what i do:
The noctua cooler has 2 fans: 1 in the middle (I'll call this one: CPUFAN1) and 1 fan on the side (and ill call this one: CPUFAN2). Then we have 3 case fans (I'll call these PhFAN1, PhFAN2, PhFAN3).
So in the hub this will be the connections
PWM HUB | Connected to:
FAN1 | CPUFAN1
FAN2 | CPUFAN2
FAN3 | PhFAN1
FAN4 | PhFAN2
FAN5 | PhFAN3
FAN6 | None
POWER | Power Supply
CPU FAN | CPU_FAN1 on the motherboard

I hope i made this graph thingy clear? Are there any errors?
 


Wow that cleared up everything for me! Thanks alot for your time and wisdom, really appreciate it man. I hope i didnt annoy you alot with my (stupid) questions, thanks again!
