[–] Taleya@aussie.zone 6 points 2 years ago* (3 children) Runs at 15,00000 rpm and produces the same db as a lawnmower permalink fedilink source hideshow 6 child comments replies: [–] AI_toothbrush@lemmy.zip 5 points 2 years ago It has 14000 times less airflow than a noctua fan iirc. link on mouser permalink fedilink source parent [–] edgemaster72@lemmy.world 3 points 2 years ago 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 permalink fedilink source parent [–] Treczoks@kbin.social 1 point 2 years ago (1 child) 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. permalink fedilink source parent hideshow 2 child comments replies: [–] gens@programming.dev 1 point 2 years ago (1 child) 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. permalink fedilink source parent hideshow 2 child comments replies: [–] Treczoks@kbin.social 1 point 2 years 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. permalink fedilink source parent
