As an engineer, you are correct!

Those that argue that Noctua shouldn't change the color scheme on their fans because it makes them identifiable should consider that there are better colors they can use for brand identification. I hardly think there are any brown-and-tan builds out there where Noctuas would actually fit in, and repainting them yourself just isn't the same as getting it right from the factory the first time.

Noctuas don't push a large amount of air. Average-at-best static pressure and the lack of any high-speed models doesn't justify their price, regardless of how much patented and "revolutionary" tech goes into them.

There is only so much you can do to improve upon the design of a typical case fan since they are limited by size in every way. Then if you limit how much noise they produce you have even less room for CFM improvement. The only improvement I could really see making a difference would be low resistance bearings and a different blade design. I personally just like to use sound dampening material in my cases with a nice set of high speed panaflo's or delta's.

Yup, Panaflos are a no-brainer if you have room for them, and they undervolt very well. There's a reason I've got 3 of them. tongue.gif

I know this isn't noctura's department, but personally i'd rather see server-level fans brought down to normal case fan noise levels.

Definitely; if people only want CFM they should go and buy some Scythe Slipstreams.

The build quality definitely does; I've had scythe fans that broke within 2 months of being bought, yet to see a Noctua break. They're the best 120x25mm case fans bar none for silence.

What about Gentle Typhoons? They're much closer to the price point Noctua fans are at and quieter when run at the same rpm in my experience.

Silence? They're far from silent unless they're turned off.

And for that matter, no moving object can be slient. I hate hearing people say a fan is "silent", if it moves, it's not silent.

Also I got the press email about these Noctua fan's. Has anybody else noticed that all Noctua is doing is literally filling their products with apparently useless technology. Yes the ND-D14 is good but you would expect it to be, it's a massive cooler with multiple fans.

Gentle Typhoons are great, but Noctua has a one up on quality over them. (Loving my 1850RPM ones, definitely putting 2 or 3 on a D14 when I get one)

GTs have better quality imo. I've used Noctua fans and I've used Gentle Typhoon fans and honestly I like the heavy and sturdy feel of my Gentle Typhoon fans. Noctuas are in the same ballpark in quality but they just aren't quite as high of quality to me. Of course, to each their own.
