No need to rage against the hive mind. All you have to do is point to a fan roundup. It turns out the 14cm Noctua is "nothing special."

I own the X-Silent 140 they recommended as well as Noctua's 14cm fan, but I haven't done any scientific comparisons myself.
I have compared the Noctua's with the Apache's directly in shop that my friend manages [coinsidentally it was comparing both the 140mm circle Noctua and 120mm square] And I can safely say the Noctua's didnt even compare with the apache's in the slightest. both at the same noise level the Apache's put out atleast 30% more air I would say more, the Noctua's really arent very good, they are just quiet [like the Apaches] but push hardly any air.
The new BeQuiet Fans also cr@p all over the Noctua's
The Noctua fans really arent all that good, as I said you can get fans just as silent but 2/3's of the price cheaper look nicer and work allot better. No brainer
