We’re gonna need a banana for scale

Runs at 15,00000 rpm and produces the same db as a lawnmower

It has 14000 times less airflow than a noctua fan iirc. link on mouser

And at such a high pitch you could've sworn it would be beyond the range you can hear but nope, there it is, piercing your eardrums

According to the data sheet, it has 17400RPM, which is 290RPS, times 11 fan blades (if I counted correctly), so it would probably run with a 3190Hz sound. The noise is actually not that loud, given as 25dB(A) at 30cm.

While it is not overly loud, a proper case design that alleviates the annoying frequency by filtering it would be a good idea.

That's close to the frequency we perceive as the loudest, so adding ~5dB would be fair. See https://en.wikipedia.org/wiki/Equal-loudness_contour It's also a very anoying frequency.

[–] [email protected] 1 points 11 months ago

Well, it more depends on the overall spectrum - and a good sound designer. I've seen miracles done with air vents filtering out frequency ranges, but that's some voodoo level stuff in my eyes.
