Ok I just got everything pretty much finished. I'm running two Phanteks PWM hubs from the CPU and OPT headers on the mobo. I've got 7 fans blowing in and 5 blowing out. Temperatures are fine and cool with an i7 6700k 4,6 overclock. I've just been advised to get a proper fan controller (sourcing power direct from PSU) rather than use power from the mobo .. is this a better idea? If so, what fan controller should I be looking at that is good quality and will take the 4 pin PWM fans (all Phantek 140mm)? I have looked at the
1. Aero Cool Aerocool Touch-2100 panel, Fan control
and the
2. nzxt sentry lx lcd fan controller
I do have dual 5inch bays free if it is needed but I need to know what's good and what's not and will also take 12 fans

Specs:
Case: Phanteks Enthoo Primo
CPU: i7 6700k (at 4.6Ghz)

GPU: Asus GTX 980 Ti Matrix
SSD: Samsung Pro 850 1TB x 3
PSU: Corsair H 1200i
Sound: Asus Essence STX2 7:1/ONKYO Amplification
Optical: Pioneer BDRW
LED: NZXT HUE
Cables: by CABLEMOD
OS: Win 10 Pro 64
Keyboard Corsair Gaming K95 RGB
 
that will mean I loose PWM control from the CPU fan header ... what I need is to keep the signal from the CPU fan header to speed up or slow down the fans but use a power supply direct from the PSU ... do I make sense ??
All I can see by installing a dedicated fan controller is that I will loose the functionality of the CPU fan header and having to install sensors to achieve the same purpose but without direct mobo control ...
 
hmmm I have been told the opposite .. at present I have all my fans running from two Phanteks PWM hubs. One hub is connected to "CPU FAN HEADER" and the other from "OPT FAN HEADER" .. they work fine and control according to the Asus AI Suite 3 settings for fan control. Likewise PWM settings in bios are "on".

The label on the sata power supply on the hubs states that the PWM signal will be interrupted once the sata cable is used and cannot be used in conjunction with PWM control ?? So to me that's an "either" "or" situation ...

I mean if it turns out that I can use power supply direct from the PSU instead and still keep the current PWM control from the CPU/OPT headers then that's great but the label states differently ..
I think there is also confusion with this warning as the manual states that the sata power cannot be connected if using "other" types of headers (eg CPUfan2, OPT fan, ETC) ???
 
i can now report that it works with the sata connections. i have two hubs connected to the cpu fan and opt fan headers and are all under pwm control. i really cant understand the info that they provided with the pwm hubs or the warning stickers on the sata cables .. the speeds are controllable through asus ai suite from about 700 rpm to 1280 rpm ... total of 7 fans input and 5 putput ..:D
