Also another thing to consider, especially in tight places like trying to push air through a PSU or fins of a radiator you have to take into account the air pressure the fan is capable of as well as CFM. The best combination of the two will help blow through a restrictive space.

The noctua P12 is probably the best performer of the "quiet fans".
For straight up performance probably "about" the best is an ultra kaze 3000....if you can stand the noise. But you could always put it on a fan controller and tune it down to about match the overall performance of the noctua yet have that extra umph if ya ever need it. The kaze has a short life span though......

Edit: been looking for this link for ya......finally found it....some sorta recent fan testing.....

The Noctua Fans mentioned in the first post be in the top 3 of silent fans!
I heard them working (or better I heard them not).

The main "problem" will be, that your PSU, GPU or even your CPU Fan is louder.

Case Fans should be the last point to take care of in a silent system.
Give it a try - unplag your current case fans for a test.
If your Systems noise doesn't change a lot, find out whether PSU or CPU Fan is the problem ;o)

SilenX for case fans, Sythe S-Flex for CPU fan. My comp is silent (the only noise I ever hear is the fan in my external enclosure ) and very cool

I have the second noctua - it is absolutely inaudible, but barely pushes any air. A deep 120mm silenX will be just as quiet, but with reasonable airflow

I've owned a few SilenX's and they've all been superb - don't let the haters dissuade you

Thread Starter 
I've looked at all the fant tests and they haven't really helped. I went with two of the Noctuas: one for PSU, one for CPU. The only loud thing is my PSU fan (and hdd of course but that's just when it revs up.)

I'm not worried about my case fans right now, since they are really quiet and move enough air for my taste. Between the Noctua and the S-flex they are about the same. I've heard too many bad things about the Silenx so I skipped those. Since 52 CFM is enough for my PSU, I'm happy. I turn all my fans down at night so I just wanted something that could get below 19db undervolted. These Noctuas should be fine.
