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

[–] Treczoks@kbin.social 1 points 11 months ago (1 children)

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.

[–] gens@programming.dev 1 points 11 months ago (1 children)

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.

[–] Treczoks@kbin.social 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.
