I'm disappointed that this is on YT, shouldn't it be on OnlyFans?

OnlyFans lost its purported audience years ago, when they made the decision to include human adult content in addition to fan-related content only. The adult content quickly took over and now you can barely find anything relating to fans on there. Reddit is a much better place for that now, and if you aren't particularly precious about documentary-style fact reporting, you're much better off browsing r/fanfiction.

I think the joke blew right past you.

Alas, I'm afraid that was you.

How much more is the BOM for a silent fan like in Noctua? I recently bought a controller for my well water pump, and it has two 80mm fans for cooling. Sounds like an aircraft when taking off and doesn't seem to move much air. I'm planning to replace them with Noctua fans.

You're not going to find a significantly quieter 80mm fan. It needs to be bigger so the blade passing frequency is in a less noticeable range.

Meanwhile 3D printing is being banned in US states supposedly to prevent people from creating gun parts, because just buying a gun in the US isn't doable for a criminal. But in reality it's because ownership of production and machines is about to get banned for the lower classes.

Not just 3d printing, the proposed law applies to cnc too.

I believe the tolerances to the fan housing (which reduces turbulence and thus noise), and the the material stiffness needed for that small tolerance, are the alleged reason there are few copycats. Supposedly getting plastic that rigid is hard. I've tried to find hard numbers and validate that claim, but I wasn't able to. Would probably have to measure an actual noctua fan blade to know. On the other hand, metal prin…

Do they add glass fibers, I wonder. That's a way to make plastic stiffer but it's a bit harder to make.

They definitely add something. Noctua has a different texture and grain.

haha true, though I don't think that's what GP meant

> you're much better off browsing r/fanfiction.

The punchline is buried a little bit too deep, but pretty sure they're just playing along.

You really don’t need to 3d scan, I’m not a cad expert and it took me just a few evenings to replicate pretty much the blade profile of my Noctua fans based on photos

Wouldn't there be too much error when you both 3D scan and 3D print it?

The 3d scan is generally used as a base for your cad model, you don’t print it it directly, you instead replicate the shapes in your cad software, that gives you pretty much infinite precision thanks to NURBS
