Are 2 140mm Front Intake & a 120mm Rear Exhaust Fans Optimal for a Corsair Carbide 400Q?

CPU: Intel Core i7-7700
CPU Heatsink: CM Hyper 212X 
CPU Fan: CM MasterFan Pro 120 Air Balance Fan in PUSH config (Towards the Rear Exhaust Fan)
Mobo: Gigabyte GA-B250M-DS3H
RAM: Corsair Vengeance LPX 16GB DDR4 2400MHz C16
GPU: Zotac GTX 760 4GB (External Exhaust, Blower Style, Reference Model)
SSD: Samsung 750 EVO 250GB
HDD: Seagate BarraCuda 2TB
PSU: Corsair RM 550x
Case: Corsair Carbide 400Q (Direct Airflow Path)

I want to use 2 CM MasterFan Pro 140 Air Pressure / 3 CM MF Pro 120 Air Pressure Fans as my Front Intakes & a CM MF Pro 120 Air Flow Fan as my Rear Exhaust. I want to keep the top covered with the silenced top panel. And the PSU fan will Intake air from within the case. I usually leave my system on 24/7; for downloading or video playback. I also casually game on this system.

Is this an optimal setup for my case?
I think the air pressure of my case will be 60% positive & 40% negative. Because even though I will have 2 or 3 intake fans at the front; they all are/will be filtered (Dust Filter). But as the rear exhaust fan will not have any sort of obstruction, I think the overall air pressure would be 60/40. Am I right?

easily for your setup, connect them to your mobo and run them at a quiet fan curve or fan speed. You gpu + cpu are probably 240watts max

Yes my CPU is 75W & my GPU is 170W. Total 245W.
