Case Fans - Fractal R4

[majax]

I'm building my first PC ever and I'm confused with some issues regarding case fans.

I want to replace the 2 stock fans that come with the Fractal R4 case with Noctua NF-A14 fans. However, I have some questions:

1) My plan is to put 2 in the front as intake and one in the back as exhaust. Is this an efficient use of the fans? I will have a SSD and one or two hard drives. Thus, I'm wondering if the bottom intake fan will just be blowing into the bottom hard drive tray?

2) I don't know if I should plug them into a a Swiftech 8 way splitter and that to the motherboard or just to the R4 fan controller. Is one way recommended over the other?

3) What Noctua fans do I get and why: the NF-A14PWM or the NF-A14FLX?

Here's some of the key components I have already:
I5 3570k (not overclocked)
Fractal R4 case
Seasonic SS-660XP2 PSU
Asus Z77 Sabertooth motherboard
EVGA GeForce GTX 670 FTW (not overclocked)
Hyper 212 EVO
SSD
one or two hard drives

Well, it seems like I have three options:

1) Control through R4 with 3 fan controller (FLX fans needed)
2) Control through motherboard & ASUS Software (PWM fans needed)
3) Control through splitter & BIOS (PWM fans needed)

Could you some advice on this. Ideally, I would prefer the fans to change their speeds based on the temp in the case.
