WHY SWEAT IT? Your brand is a non-black fan. I'd stay with that. Why confuse people. Maybe trademark your fans colors.
Why does it take so long to release black fan versions?

All white builds are common. There are a lot of white GPUs, motherboards, RAM, cases, and fans. If you need daily dust cleaning you should invest in a room air filter.
Common? Less than 5% of the market. Is that common?
They typically don't require any custom one-off parts to be made, just mass-produced off-the-shelf stuff, so they're common enough.

#293Just paint it black, no one will care, you'll save money and sell more units.

Reminds me of this story from lego:
I gave the ducks just two coats of varnish, not three as we usually do!

It seems that common means something very different to you and I. Less than 5% of something is common? To me that sounds like the definition of uncommon!

The difficulty is clearance between two moving parts, with blades that deform slightly due to air pressure (at different amounts for different speeds) and with thermal expansion.
That’s not what the article says, they relate it to reproducibility of the manufacturing process: “Achieving such small tip clearances is essentially at the absolute limit of what injection moulding can consistently reproduce”. Though maybe they misphrased that, as for example Lego pieces have significantly smaller tolerances and are also manufactured using injection molding.
Clearance vs tolerance is important. Clearance includes all of the things I said.

#297This is content marketing executed perfectly :) Reading it, I learned something new and interesting and they had an opportunity to show off one of their differentiators against the competition (low leakage flow due to tighter tolerances) and then at the end they casually mention the new product that has just opened for pre-orders.
Exactly this. Most of the time you get poorly researched articles (or nowadays, AI slop) about some topics only very remotely related to what the company actually does. Here, the article is about something interesting that the company has expertise in (and even "insider info"), shows off that they do serious engineering, and is interesting to the target audience. If I'm buying a 12V or 5V fan, it'll almost certainly…
Noctua are pricey but they also provide service that is in my experience unmatched.
We have a few hundred of their coolers in use and I have never had an issue getting warranty replacements from them with fans. The process is simple and they ship out a new fan ( I have warrantied probably 10 - 15 of the fans)

Wondering if it's just the marketing that Noctua did, and the actual mold and process engineering left to some fab in China?
With Noctua I highly doubt that is the case given their track record for quality overall and all other information available around their design and engineering process. As far as I know based on all the information I have seen all the design and engineering is done in Austria. They also have a track record of only releasing things once they are satisfied something performs within their standards. Something that woul…
The other thing to consider is that while China is known for making cheap items for the American market (because that is what Americans want) they have become experts in the tool and die needed to make those cheap items.
If you want top class injection molding tooling / machines or process you are probably going to contract a Chinese company to do it.

Normally I love this kind of article too because I consider it engineering, not marketing, the product name dropping at the end just reinforces the message. But either I'm missing some details that could have been spelled our more clearly, or the engineers were taking a break when the marketers were writing some parts. I'd love to stand corrected if someone more informed has details. > advanced polymers such as Sterr…
Expert here. When very precision molds are made, what Noctua talks about in "multiple tuning iterations are required until the geometry, cooling, gating, and moulding parameters are perfectly stabilised" is the standard process for this type of stuff. (Gears, bottle caps, or any molds than make 8, 16, 32, 64, or 128x of the same part in one shot, require that you start with "steel safe" geometry, meaning you mold the…
Noob here. If you dont mind ive got some questions for you!
Ive recently started messing with the idea of making my own model car kits as a hobby. I understand a lot of the basics, but have never done anything like this before.
Im obviously not going to make kits in mass, but, i plan on doing injection molding using polystyrene. I do not currently have a cnc, but have been eyeing a SainSmart, though they say "can do metal under certain circumstances", but doesnt cover any of those circumstances. I also was looking at various injection machines and the price for entry is insane to me - $1000 for something that would probably burn your house down.
Anyway, to my questions..
1. Suggestions for a hobby cnc that can work aluminum? Id be willing to go as far as $2kUSD, unless theres something more that you think would serve me significantly better 2. Suggestions for a hobby injection machine that can do ~60-100g shots, that wont try to burn my house down, and doesnt cost a ton? 3. Any tips or thoughts for someone diving in to this? 4. Things i should purchase for QoL with cnc or injection molding? 5. Where does one buy materials (in hobby quantity) like aluminum block stock and polystyrene pellets?

#300> These surface vibrations are so minute that they are not critical from a mechanical point of view (unlike e.g. vibrations due to imbalance), but they can cause serious acoustic problems. The reason for this is that when the fan is running, there is a pressure difference between the intake and the outlet side of the fan (lower pressure on the upside of the blades, higher pressure on the downside of the blades). From an aero-acoustic point of view, this situation is similar to a stereo speaker where there is higher pressure inside the chassis and lower pressure outside the chassis. In both cases, the pressure difference leads to an efficient acoustic coupling, so the surface vibration of either the blades of the fan or the membrane of the speaker is transferred to the air.
I love rotary woofers :) I hope to get one some day.
