For such few words in a title, this is a rather complicated topic...
This site helped set me in the right direction, but I'm wondering if further improvement is possible for my planned setup.

Fan durability is not an issue for me, I strictly want efficient static pressure performance due to effective blade design. I'd like to keep the cost of the fans under $20 per fan, and under 2000rpm for noise reasons. I'm willing to exceed these limits to some degree, but no 5400rpm AP-31s...
Here's where I'm currently at for my planned fan sandwich:
1) Pushing fan: Cooler Master Blademaster (claimed 3.9mm pressure @ 2000rpm)
2) 25mm spacer
3) Radiator
4) 40mm spacer
5) Pulling fan: Another CM Blademaster? Is this fan even meant for pulling air, or is it just meant for pushing?
From what I've read, the Gentle Typhoon AP-15 (1850rpm) only puts out around 2mm pressure. The engineers at CM seem to know what they are doing, and recommend the Blademaster as their push/pull setup. Are there any fans worth considering from another manufacturer? It's unfortunate that CM doesn't make a ball bearing, or 120x38mm version of the Blademaster...
