Why does it take so long to release black fan versions?(www.noctua.at)

I always expected that black was the easiest color, since you just add enough pigment to wipe out any colors from other materials. Are they implying that that brown color is the natural look of the materials they used, so the simplest to engineer?

From what I understood, any color and material involved in high precision manufacturing requires careful design and thorough testing. They likely prioritize the brown color and material due to branding, so changing this to anything else requires redoing large parts of the pipeline.

Large parts is kinda exaggerated.

You have to redo injection moulds anyway as they have a limited life. And you can do a lot with materials too, some materials simply shrink more than others as they cool down.

Blue. Make blue fans.

I think I have 20 or so Noctua fans from 80 to 200 mm from 1-8 years old, haven't had a bearing or motor failure yet. Cross fingers.

Interesting.

I'm glad companies like Noctua exist that put so much thought and care into their products. I don't even mind being advertisted to when that's the case.

Reading about this, just makes me wish I has good 3d scan of their impellers to see how a simple 3d printer will deal with such mythical precision.

Noctua is awesome in a lot of ways, one of them is offering full CAD models: https://www.noctua.at/en/3d-cad-models

One of the first things mentioned on that page is:

> To protect our intellectual property, certain features – such as fan impeller geometries – have been slightly modified while remaining visually very close to the actual product.

So you do have to 3d scan them yourself if you're trying to print a copy.

Depending on what printers you have available I'll put in the work to get you a ~0.02mm deviation scan of a blade off a 120mm noctua fan I broke. I expect it to under-perform notably due to the surface texture and the lack of rigidity under load causing contact with the shroud walls at high RPMs, but I wouldn't bet my lunch on it, would be fun to find out.

The texture has substantial chance to actually help. Check golf balls.

The materials that you could use in a 3d printer are not rigid enough.

The blades of the fans are fiber-reinforced, in order to have sufficient rigidity, even when very thin.

Only a 3D printer for metals could print something rigid enough, but such a metallic fan would be too heavy for a computer fan.

Obviously better if you print slow enough. But the fans will be weaker and you won’t be able to pump out thousands every day.

Somewhat unrelated anecdotal praise of Noctua: due to various life factors, I hadn't built a PC since maybe 2010 or thereabouts - something I did relatively often before then and had quite a bit of experience with. Then a few months ago I finally did it again. Forgetting about the absurdity of the RAM situation, I gotta say my biggest surprise was cooling. I wanted a quiet media center machine. The internet and friends kept recommending Noctua. While researching, I got a bit of a cult vibe, and their prices seemed a bit stiff. But I went for it, with some hesitation.

Goddamn was I wrong! Their CPU coolers are the most well-designed, thoughtfully planned, amazingly performing consumer product I've seen in a while. 10/10, highly recommend! I'll use them for all PC cooling needs going forward.

I sometimes wonder whether they have an culture that overengineers tbh.

The thoroughness & mindset is certainly appreciated, but you can also overdo it - engineer it beyond what the consumers use case requires.

Where do you draw the line though? They have an amazing reputation for quality fan products, they clearly feel it needs a new injection mould which aren't cheap investments.

I've got a Noctua NHD14 in my current build that I bought in 2011 and it performs perfectly still (including 2 free socket upgrades from Noctua).

> engineer it beyond what the consumers use case requires

This mindset I think is why companies tend to favor releasing slightly broken and shit stuff, instead of waiting until they feel like they made something the best it could.

While I don't think they do, I think this is a valid thing to ponder and I'm sorry it's getting downvoted.

Generally, I think it's not overengineering that's the issue, it's how the consumer need for that particular level of quality/performance is marketed to the wrong audience. Cars are the classic example. Most people who drive a car that was precision engineered for speed or offroading capability rarely if ever need that functionality.

That said, in a world of consumer good racing to the bottom and physical enshittification, I'll generally pick the item that's obviously well designed, even if beyond the capabilities I need. The alternative is often a slew of indistinguishable crap.
