Maybe he detected 0 RPM without looking at temperature.... some controllers will just stop fans when there is enough cooling.
We had a bunch of racks and fan failures gotta be one of rarest one. Even on my personal junk I had zero actual failures, just one getting noisy

Not really different than cloud, they aren't buying top of the line servers, they are making their own just like hetzner, for cheapest per performance unit.
Are controllers that throttle down to zero common in the data centre space though? I don't think I've ever heard a quiet or silent server, except for the ones tech people make themselves at home.
Hetzner is known to do their own thing instead of blindly following datacenter conventions. E.g. having the physical architecture (how their buildings are designed) so optimized for convective flow that they get sufficient air flow without extra fans most hours of the year and only need active "heat pump" style cooling in rare exceptions. They do have board-level fans, but it it would be almost out-of-character if those did not throttle to zero whenever possible.
