Suggestions for Fan Replacements

Heya people!

I'm trying to hunt down a set of 3 good fans (120mm) to replace my current Ultra ones (don't remember which ones exactly) -- but I looked their fans up, and it seems the ones they have available (that look like them) are specced at ~26dba / ~70CFM at full load.

I'm prioritizing noise because my computer's quite a monster -- eliminating three of those (particularly the two on my water cooling radiator, which is close to the openings in the case) should make a substantial difference. But of course, I'd like them to be efficient.

Right now I have my eyes on these --

- Noctua NF-S12-1200 - ~48cfm @ ~17dba
- Noctua NF-P12 - ~54cfm @ ~20dba
- Thermaltake Silent CAT - ~38m3/h @ ~16dba

UPDATE:
- (by Juggalo23451): Scythe SY1225SL12L 120mm "Slipstream" - ~40m3/h @ 10dba

I'm ignoring price for now; but is there anyone with any of the above fans who can vouch for these specs?

Any other good suggestions would be appreciated.

Cheers!

Seems like a good runner up -- but at ~40cfm @ ~10dba it still seems running the Noctua NF-P12 with the noise adapter at ~78cfm w/ ~17dba would be a more efficient choice.

Anyone that can verify this is true? Or suggest any other fans?
You're reading the specs wrong, that's not CFM. They have the CFM conversion here:

Anyways, I recommend Scythe S-Flex paired with a good fan controller. High quality build and they use Fluid Dynamic Bearings, they also undervolt well. The Slipstreams are cheap fans that use 80mm motors with sleeve bearings, nothing really good about that except cost.
slipstreams are little louder than the noctuas.

I have both, and no way Noctua NF-P12 is 92 cfm
Ack, I completely missed that. Sorry about that! Updated.

Much appreciated!

How effective are the two for you?
