How to make the Framework Desktop run even quieter (noctua.at)

In combination, the custom side panel and duct design provided a massive noise reduction compared to the stock configuration, particularly in lower fan speed ranges. We have measured around 7 dB(A) lower noise levels at around 50% fan speed, and up to 5 dB(A) lower at higher fan speeds, when compared at the same APU operating temperature.

While the custom side panel with our signature Noctua grill as well as the custom fan duct are not slated for mass production at this point, we are more than happy to share the 3D CAD files for everyone who is looking to make their Framework Desktop run even quieter.

Both the custom side panel and the customised fan ductare available to download at Printables.com for you to 3D-print at home

Because filters restrict airflow.

Like I said, if you use a centrifugal fan it doesn't restrict airflow.

Every air handler on the planet uses a centrifugal fan with a filter because they can generate vacuum/pressure.

That makes no sense. Anything you put the air through causes a restriction.

They mean the fan is rated for that amount of restriction, and will still move a decent cfm of air. Regular pc fans will drop cfm very quickly when there's any restriction.

It doesn't matter what it's rated for. The basic principle doesn't change.

Some fan designs handle restrictions much better than others. PC fans will drop to basically zero airflow with a moderate restriction, while centrifugal fans will still move a decent amount of air with that same restriction.

And yet, once again, the principle doesn't change. More restriction = less flow.

The principal doesn't change, but the magnitude of the effect does.
