So just use Noctua fans? That'd do it.

It's more than just the Noctua fan. The fan grille is a contributing factor to noise [0]. The new design features in the article could reduce the noise of any 120mm fan. [0] https://news.ycombinator.com/item?id=32923226 https://news.ycombinator.com/item?id=32923226

Its been a while since I looked into "just use Noctua" for $another_use_case, but ... Isn't the problem with Noctua (and similar "silent" fans) that they don't offer the same airflow throughput as their noise making bretheren ? So sometimes its not as easy as "just use Noctua" ?

  Noctua makes 2000rpm and 3000rpm max variants of the NF-F12. Otherwise, through (over)engineered geometry and materials, their fans usually do push the most air volume and pressure at a given volume level, with a more pleasant sound profile. But you pay for it.

    Worth noting that you are also paying for the service. I have RMA'd many fans through them and the experience is quick and painless every time.

  For some applications such as cooling of an extruder for a 3D printer Noctua fans indeed don't offer sufficient airflow. But I don't think that's an issue for computer cooling unless you're talking about extreme circumstances.

  Noctua fans are quieter than most for a given airflow level. They have a range of fan speeds going up to very high speeds. Many people doing modifications will substitute a lower airflow fan for even more noise reduction, which might be why you’re thinking they flow less. That’s a function of fan choice, though. Noctua fans perform very well on a noise-adjusted basis.

  I think noctua fans are just better fans, noisewise. They have better airflow design and sound dampening/isolating screw mounts. I think the idea about reduced airflow might be backwards - most systems use PWM to spin the fans based on CPU or system temperature. This means the systems get the airflow they need. Also, they make larger heatsinks + fans for certain systems that allow the same airflow using a larger, slower spinning fan. which means less sound. that said, there are some noctua fans that can spin faster than others.

  Their big fans do push enough air, the small ones are questionable If you're looking for 40mm or 80mm you're better off with sunon maglev or similar

Well the fan in the Framework desktop is some kind of purpose built high performance Noctua fan that is significantly louder than usual. So they are suggesting to use the new grill with the fan that comes with it so you don't encounter throttling.
