difficult due blade possitions may create some nasty turbulence for the next fan in line. Might end up with some nackered/very noisy fans.

I dont see how pairing fans up in series can do anything, your already moving the same amount of air....

If you push a fan too hard with another it will simply die ;D

You would be better off putting a fan on top somehow.

I think they provide better pressure and therefore actually push their rated CFM. Push/Pull setups always beat (haven't looked into this much but I think) single fan setups so there must be something going on there

But do push/pull arrangements actually beat single fans? Or is it just "More must = Better"?

It's got something to do with the pressure. The 38mm fans do better than 25mm ones because they have a higher pressure. There are various threads on it on the net where the users find that using 2 yields better temps or allows them to lower the fan speeds while keeping temps the same (for quietness).

then actually i'd recommend the PFB1212UHE. it produces 252CFM

but that's just insane :P

putting these on a radiator in push/pull with shrouds would be insane...
