New H440 Fan Hub Problem

[himen256]

HI guys I got a quick question. Just finish installing fans in my H440 but now top and front is not spinning.

I have on top 3x NF-S12B redux-1200 PWM,
in front I have 3x NF-F12 PWM 1500 and back is NF-A14 PWM.

I do have Hyper 212 EVO with it stock fan for CPU.

Now top and front are all connected to 3 way pwm splitter with low voltage adapter from noctua. So 3 fans from top go to one PWM cable then to low voltage and then to Nzxt fan hub, same for front. Back is straight to low voltage and to fan hub and is working fine same for CPU fan that is connected to fun hub with no extensions or adapters.

What could be a problem not enough power from single PWN to 3 fans? Or low voltage adapter is not strong for 3 fans per one low voltage adapter?

BTW: top fans are in side case as I could not close top lid with them on out side shame.

I think you've made a bit of a mess of things.

PWM fans should be connected directly to 12v and the PWM signal of your motherboard for them to operate. They should not be connected to a LNA adaptor or a NZXT Hub (assume this is the PWM converting hub with active electronics and not the dumb fan hub from before).

Not sure how you are going to control all those fans with just one PWM splitter. If the EVO has a PWM fans that'll be 7 fans off potentially one header. Might be a tall order.

I can see there is a bit of confusion here, so let me explain:

Top:
3x NF-S12B redux-1200 PWM >>>> EK-Cable Y-Splitter 3-Fan PWM >>>>Noctua Low Voltage Adapter >>> Nzxt Fan Hub.

Front:
3x NF-F12 PWM 1500 >>>> EK-Cable Y-Splitter 3-Fan PWM >>>>Noctua Low Voltage Adapter >>> Nzxt Fan Hub.

Back:
NF-A14 PWM >>>>Noctua Low Voltage Adapter >>> Nzxt Fan Hub (works fine).

CPU:
Hyper 212 EVO with it stock fan >>>> Nzxt Fan Hub >>>> To CPU Fan Header..

So my Fan Hub is connected to Motherboard CPU fan header.

Before everything was working fin with old fans... now when I start PC top and front fans start to spinning but they are off before I hit windows. Only CPU and back fan are spinning, even so all fans in my case are connected to fan hub.
