Will this setup have enough cooling?

[Mathematical]

I am planning to build a 4 way sli

 

corsair 900D

128 GB g skill ram

Asus rampage V extreme / X-99 E WS

x5960 procesor

4 EVGA Titan X

PSU EVGA 1600 T2

raid 0 with 2 Samsung 850 pro SSD

 

cooling

corsair H100i for the CPU

3 120mm Noctua industrial 3000 RPM for the front intake

6 140 mm Noctua industrial 3000 RPM on the bottom sides

1 140 Noctua industral 3000 RPM for the rear exhaust

2 140 Noctua industral 3000 RPM for the H100i rad on the top and 1 140 mm next to it

 

Will this cooling set up be enough to keep the graphics cards cool?

Each Noctua 140 mm has 269m^3/h  and the 120mm has 186.7 m^2/h at ful RPM.

 

Is there a way to improve air cooling further for the graphic cards withour resorting to water cooling?

I don't see why you would need 4 way SLI for the strongest graphics cards on the market, but yes I do think this will be enough cooling, but probably add more. Also, why would you need 4 GCards? These will definitely make your cooling a piece of crap.

This build is not for playing video games. It is for deep learning.

You'd be fine with the 2 fans on the cpu cooler and the 4 fans on the  Titan X' that act as exhausts. If you want to maximise their cooling potential, I'd put all the other fans as intake, to help the blowers on the video cards.

I can tell that you won't be hearing much more than loud buzzing. You don't need high pressure industrial fans for ATX case. Not even such big thing like 900D. Nor you need to fill every hole in it. It has places so that you can choose between different option, or rather different water cooling option.
