Yes it is. As sSebaSs said, it's worth every penny
The part that I love the most is how the fan is 99% silent up to about 1500 rpm, but it still puts out so much air at those low speeds.
I don't regret having bought mine; I do regret having sold one of them though... It went to a good home, but I still miss it. Maybe some time in the future I will buy a few more and use them on a WC setup. Waste of fan power, but that's what we are here to do anyway.

I had to sleeve my Nidec... The bare wires were driving me crazy.
Molex for power + One connector for RPM sensing (to motherboard) and the fourth wire for PWM cotrol.

I live in indonesia, but finding that Servo in this country was really such a PITA
but I really courius, how do you rate its building quality, nothor? if it's compared to other metal frame fan?
inVain,
first, while unpacking the two Nidecs, i was disappointed regarding them beeing "made in Indonesia" because i've expected to recieve "Made in Japan"-ones like xXSebaSXx has.
The aluminium die cast frame looks very rough and industrial, due to the visible scratches where they cut off the unevenness from the cast process.
This looks a bit crappy compared to the beautiful frames the San Aces have. Also you can find some soldered-looking cast noches in some places.
But as much as I can see so far from the pictures xXSabaSXx shared with us, it’s the same with them.
But later, when working with the fan you can feel its high quality: The fan is rated 1000 – 6.300 rpm. Mine is running 1000-1008 rpm minimum and 6276 max. This is nearly perfect! On every speed, you can feel absolutely no vibration at the fans frame.
It is perfectly balanced and makes you trust it to work for years without any problem. See the red balancing material looks-like-blood glued into the impeller:
When turning the pot, the fan reacts smooth, not too sensitive, not too clumsy. It takes some seconds until it runs full speed. But when you cut of the power instantly, the fan makes a full stop immediately! That impresses me much. From 6.276 rpm to zero in less then 1 second! WOW!
Beeing controlled by a pwm-controller, and turning the pot immediately from 100% to 0%, the fan slows down from 6.276 rpm to around 470 rpm for 3 seconds and then fires up to 1.000 rpm again. That’s understatement :-D
Next is a bug-free tach signal. My mobo (MSI H57M-ED65) shows a clean rpm-signal. Some of my delta’s doesn’t.
Another issue: Sound. At minimum rpm you can hear the air being sucked through the blades. Increasing speed increases the sucking-air-sound accompanied by the motor-sound which sounds like a jet engine.
When running 470 rpm, you can’t hear anything it at all. Overall, you never have a clicking, tickling, rattling or whining noise. All what you hear is the air being sucked and later the jet engine sound at higher rpm’s.
Definitely the best quality fan I ever had. It would be a perfect one-4-all-fan when it would be able to run constantly around 500 rpm minimum, then it would beat out ever other fan in every possible cases due to absolutely not being audible then. But so it’s application area is limited to cpu-cooling I think. It would fit perfect on the new Noctua NH-L12 or even any other 120mm fan capable cpu-cooler.
You're right, its insane, i love it

Every time I see one of these metal frame fans I go nuts! Where can I get one! How many dollars do I need to save!
Are they really loud at all at min RPM? I would love to use just one as a rear case fan and have it painted black or maybe mount it up front somehow and beautifully lit to show off the crazy looking body.
Is there any way you could put it on a molex with its own little fan controller to make it behave and stay down below 1000rpm? Then again I have 9 Scythe GT's at the moment and I don't think I would hear it over those.
They are insane pornography and I want one. But would it want to kill me and make me deaf?

JR23,
i've made some videos to tease you I hope it's possible to get an impression of the noise profile of the (two) Nidec Servo G1238B12BBZP-00, when built-in a computer case. Perhaps it helps you.
If you have a closer look to the Data Sheet Page No 36, you can figure out that the fan would work with even 9.8V power supply, which usually causes decreasing speed and noise. If you're able to power the fan this way, i'ts possible to get it even less noisier.
Tried to feed it with 5V or 7V by the molex voltage mod, the fan does not run. The only way to control it is by pwm'ing them.
But, is it desirable to power down a fan thats made for high cfm applications?
The only address i know which has it in stock is e-jpc.com.

Oh man thats way too awesome!
I want them! Then I want to do some serious modding to my 600T. They look prettier from the exhaust side though. Would be difficult.

They would look great as exhaust fans on the case's top. If you're spending the money to them, you would love them. Make shure to control them via pwm-functionality- Have look right here for further advice.

is a separate fan controller the best way to go for them?
I wonder if they would get on with corsair link, I had seriously thought about getting that a while back but I was short on cash when it was released.
I agree two exhausting in the top would look amazing with a different cover arrangement to what there is at the moment.

nothor i thought, that it will suck you in, when You let them work on MAX... 
Anyway You are running fans, that aren't new anymore... Are You filling them up with some oil or anything like that (to the bearing or something)? How are You taking care of them? How often do you do that?

You will have to make your own PWM controller for them. Here's why:
1. They draw 54W when running and almost 70W when starting up. So most "retail" fan controllers out there are just going to melt when you plug these in.
2. Even if you were to find a fan controller that was capable of feeding them the necessary power; they work on a different frequency than normal PWM fans. Normal PWM fans work on a range from 16KHz to 25KHz; whereas these fans work on a range of 500Hz to 5KHz so the "retail" PWM controllers out there won't be able to talk to the fans.
