I'm a little unclear why you need a fan controller.  Your MB has a CPU fan header, two fan headers, and a pump/fan header.  I assume you're using an air cpu cooler.  You can only fit 6 fans in your case, though more with push pull radiators.  This is where y-adapters come in.
 
Each header usually supports 1 amp, while a single 120mm 2000rpm fan pulls about 0.1 amp.  You can safely put four of those on one header with normal y-adapters.  You can move your existing three fans to the top and back of the case as exhaust running off one header, then get two Noctua 140mm 2000rpm industrial to mount in the case front intake running off another header.  Three of the 120mm 2000rpm industrial would flow about the same and work on one header but cost more.

If you were feeling really frisky, you could get two 3000rpm 140mm industrial fans, but they would each need their own header due to drawing 0.55 amps each.
 
Noctua's come with a y-adapter and extension cable.

Kevin, don't forget the startup on some of these fans will exceed the limits of the header so it's best to be cautious and not put too many powerful fans on a single header.  

Could get a simple fan hub that is self powered and grab PWM signal but you'd need to make sure you have PWM fans for it.  

I decided to order a 4pin PWM 120mm noctua for the rear and that will be the fan I'll plug into the white FAN pin on that controller.  Then we'll know whether the hub can only correctly read 4pin fans for PWM support.
 
Currently I set Smartfan settings to PWM/Voltage/Auto for the hub,  then with combinations of the sensor reading CPU/PCIE and Case. No matter what I did the fans never change speed.   If this 4 Pin fan doesn't get variations I'm drop kicking the hub into the trash and look at other options.  I still took note of the cooling options you mentioned in that first thread.   I'll go through every option including liquid cooling and if I still can't get the fan below 70c I'll either RMA or step down to 1080
 
At my current temps my only option is 1080p.   Even just testing on 1440p (DSR version) is pushing the fan to 75c.   Why have a 2080 if I can't get it cool enough to run at least 1440p?
 
But hey I'm gonna go through all the cooling options and hopefully other beginner enthusiasts like myself can learn something through all this when they search the forum.
 
P.S.  Do you know of a review/comparison chart between the Noctua fans and the Gentley Typhoons? Thanks.

All you need is two 140mm or three 120mm powerful fans in the front, with your existing case fans in the top and rear.  This is about as good as it gets.  It's not particularly complex and this is a very standard setup. 
 
The dual 140mm 3000rpm front setup, one per header, would be the best and would only cost about $60.  You can get a triple splitter to run the other three fans off the remaining header.

So I went with the 120mm A12 and my fans arrived and I went with this setup, swapping around fans.
 
3 x 120 in the front
2 x 120 in the roof
1 x 120 in the rear
 
Still using the hub for now.  (Yes 4pin fan in Fan 1 was required for PWM to work.)
 
Same test as the previous post for 2k:
 
GPU: 74c
CPU: jumping around from 68c to 78c  (****???)
 
Result: Everything much hotter and much louder to boot, doh.
 
You mentioned something about a dead point around the GPU? I wonder if I have done this.   But either way I think I need to drop kick that hub against the wall and use splitters directly to the MB so I can set the front fans to be a lot faster than the rear and roof fans.

Please load up HWiNFO64 and log your fan rpms while testing.  What are they?  But if you're running them all off the hub, you're only going to get a reading from the main fan and don't know what the voltage controlled stock fans are running at.

So you're running three A12's in the front and the stock fans in the top and rear?   Are they pointed in the correct direction - intake front, exhaust top and rear?
 
You have 3 headers, 3 y-adapters and 6 fans.  You should be able to configure it so the 3 stock fans run off one header with two adapters, then the A12's off either 2 headers and one adapter, or the fan hub.
 
Since you didn't follow what I recommended, I'm not surprised you got poor results.

Another thing worth trying is disabling the top forward fan and just running the rear and top back fan as exhaust.

Doesn't really make sense. More airflow is better. There's no advantage to blocking up the back in order to create "positive pressure". That's a myth that should have died long ago.
You want more air in and more air out. Less air out will create less air in.

What do you guys think of this?

UGH.  I just realised a massive post I typed up last night I didn't hit sumbit
 
Summary:  I have the GPU stable around 70c but the CPU is spiking like crazy like 68 to 78c.    Before these fans, when I just had the front 3 fans, I was able to have both stable at CPU60 and GPU 70.  So the mystery for me now is why has adding the new fans
 
Edit: Just noticed your HWiNFO64 suggestion.
 
Edit 2:  Okay will shut off top fans in a test and will also try your original 2 x 140 suggestion and order those specific ones, although I am not a fan of a lot of noise but hey maybe it's noise cancelling headphone time and time to say goodbye to 7.1 surround system :(

What I've tried, and then running the same load test:
 
1)Setting the fans to all be blowing at maximum at all times had no impact on the temps.  Still the same temps as when the fans were set to silent.  (If max fans doesn't lower temps then PWM won't either right?)
 
2) Disconnecting front top fan / disconnecting back top fan / disconnecting both top fans had no effect on temps
 
3) Changed CPU to Normal instead of max.   GPU temp didn't change, CPU overheating to 77 - 80c.  Seems my CPU only stays in mid 60s with its fan at max at all times.
 
4) Using combinations of the above and monitoring the front hub fans at 70% and %100 on the controller made no difference to temps.
 
5) Set case fans to max, set front three fans to lowest speed.  No change. ????
 
It feels like no matter what I do to the case fans, my GPU and CPU stubbornly stay at around 65c to 69c, regardless of the speeds of the case fans, regardless of negative and positive pressure.
 
I have not flipped the top fans to become intakes yet, but after doing that I'll try a Dark Rock 4 Slim for the CPU.    I'm not sure what to do for the 2800 as didn't you say the Hybrid kit is discontinued?
