They’re moving air through a channel that’s about a mm high, yet claim “dustproof” on that page. Is that realistic? Also, could a hacker build something like this (but likely much less efficient) at home by taking apart a DLP video projector and playing a carefully constructed video loop on its micromirror (https://en.wikipedia.org/wiki/Digital_micromirror_device https://en.wikipedia.org/wiki/Digital_micromirror_device)?

According to LTT video, the 10x static pressure allows for dust filters.

  such claims without tests to validate are kind of useless. they're just taking the company at their word.

      you've misunderstood my point -- I'm saying manufacturer claims need to be verified. 10x doesn't mean all that much to begin with and, moreover, fan static pressure claims from manufacturers get verified by virtually no one. a shady manufacturer could straight up make up these numbers and no one would be the wiser because of that lack of independent verification. it's like if a CPU GHz figure was taken at face value, without testing.

        The Linus Tech Tips video says that it's a commercial product for use in factories where dust and other airborne material mean they can't use fans for cooling (apparently, similar previous products from this company used passive cooling). However, the marketing images on the product page don't match with this; there's definitely a lot of images of use at home. I'm not sure whether it's a consumer product or not.

        For small companies/startups, selling a niche product, direct to consumers is rarely worth the time. You have a small team that should be putting their effort into selling/packaging thousands with each call, not 2. The company lights only stay on if the collective sales goals are met. And, shipping to Joe Shmoe can easily cost money. This is why places like Adafruit exist: direct-to-consumer is a huge pain.
