Optimal Positive Pressure Cooling for NZXT H440

I'm aiming for positive pressure with front panel: 3x120 - intake

                                                         radiator: 2x140 - intake

                                                         rear: 1x140 - exhaust

Is there too much intake going on even for a positive pressure build? Maybe make one of the rad fans exhaust?

Also, how is the noise level on full load with Kraken x60 fans? Should I replace them?

I don't own a Kraken X60, but based on the review and comparison of the cooler by TTL at OC3D, even the silent mode on this system isn't all that quiet. I'd suggest checking out his comparison AIO water cooling video, its very informative
