Wrong, So Damn Wrong...
If you mean, and I'm not certain what you mean by that extra large superlative phrase "as good as". But if you are attempting to say "as decibel efficient" or "move a greater volume of air at decibel ratings of 4db, 6db, 8db, 10db, and 12db" since any auditory output above the sound floor higher than 12db most persons can actually hear at 30inches away from their head and ears, then you are So Damn Wrong.
The Sanyo Denki Silent S-Type fans are much more decibel efficient at any rpm than the Noctua NF-F12, and even the Noctua NF-S12 ULN series that only produces 6db, it pushes much less air at those 6decibels than the Sanyo Denki Silent S at 6decibels.
So why aren't they popular? One reason is you can only purchase them from a distributor like this one:
And although the base price looks only slightly greater than the Noctuas, these distributors charge a flat base rate for shipping and sales tax no matter where you live, so buying only one fan can double the cost, and they arrive unsleeved 3wires, so factor in the cost of sleeving each one. My first three were about $37each after sleeving, and my last two about $42each so roughly 5 fans cost $200. The trick is to know how many fans and the type you need and make the fewest number of orders to reduce your cost.
I do agree with you Corsair fans are substandard in comparison, but Corsair knows what they are doing, (and I respect them for it) they make much much much more money from the enthusiast market selling you just average quality fans with bright colored rings around them, than Sanyo Denki does. Sanyo sells to the enterprise and server markets and the fans are made to work in perfect silence inaudible if you like at 1000rpm, 800rpm, 600rpm, 400rpm, whatever you prefer for 10years PLUS.
I own 3 of the Corsair SPs 3AFs, and more Noctua fans than I can count. Still have my old NH-D14 since it came out October 2009.
By the way, the Sanyo Denki Silent S fans are the same fans Seasonic and subsequently Corsair uses in their amazing world-class Platinum AX Power Supplies.
I'm using an Aquaero 6 to run my 5 Sanyos, but any good quality controller will work. Also have an inexpensive Lamptron that spins them inaudible as well.
