Help me decide which fans to get

[Deleted member 526847]

Case: NZXT H2

Current fans:
Stock 120 mm NZXT fans x2 at front
Stock 120 mm NZXT fans at back
Stock fans with Noctua NH-D14

I have one empty slot for a 120 (140) mm fan and one for a 140 mm fan.
I am also considering to add a third fan to my NH-D14 as well as changing the cooler (reference) for my XFX 6970.

Questions:

1) Which 140 mm fan should I get? I've been looking at Noctua's NF-P14, any other suggestions?
2) Apparently the NF-P14 fits in the bottom 120 mm slot, so I guess I'll use the same fan there as the answer for 1) (unless a 120 mm does a better cooling job?).
3) According to others with the H2, they've gotten better temps and sound levels when they've traded their front stock fans to other fans. Question here: what's better, Noctua's NF-P12 or Scythe's Gentle Typhoon? I know the GTs are good with heatsinks, but what about sucking air into a case?
4) Like I said, I have the stock fans with the NH-D14, do you think I will have any benefit from changing the NF-P12 there to, say, a GT?
5) I read a thread about adding a third fan to a NH-D14, http://forums.extremeoverclocking.com/showthread.php?t=357131, do you think it's worth it?
6) What do you guys think about changing my reference cooler on my 6970 to an Accelero XTREME Plus II? Can you recommend a better cooler?

I know it's hard to say that one fan is better than another, but considering I'll add five of the fans to a fan controller, I'll go for the one with superior cooling.

Thanks in advance!

I just bought the accelero I havent mounted it yet but it is the #1 VGA cooler for air. It beats the Gelid Icy by lower noise and cooling levels. You would have to go water for more cooling.

I just bought two of these

For my case, they are loud if you hook them up to just a power supply because they are 2000 rpm. But if you hook up to Mother board they can run 1400rpms and be almost silent. They move a TON of air. Plus they are cheap. Then you can buy a Y splitter like this

And run the pair off one 3 prong on the MB.

I seriously doubt you need a 3rd fan to cool a SB CPU.
Top tier coolers like the D14/SA/Genesis were developed to cool i7 9xx series.
Don't get me wrong Noctua fans are top quality but pricey compared to other top tier makers.

So I've followed pretty much everyone's advice on the Thermalright TY-140, however, it only fits 120 mounting holes. Does anyone know if it fits the bottom 120 mounting holes of a NZXT H2-case (hard drive bay next to it)? I'm not sure about the measurements.
