You say you measure noise but you didn’t provide any real comparison on noise performance with the other fans, instead relying on a couple of contradicting sentences…
I looked at the specs on mouser. AT got within 11% of the manufacturer listed specs for pressure and within 2% on flow volume. Of course, AT's noise figure is much higher because they're measuring much closer to the fan.
" In short, these fans are not meant to be installed with the engine facing upwards, as this can jeopardize the integrity of the Vapo mechanism. As a result, Sunon's MagLev fan is really only good for horizontal uses – front and back air intake/exhaust – and shouldn't be used for vertical configurations at the top and bottom of computer cases."
The original paragraph is ambiguous - does "horizontal uses" mean "attached to a horizontal surface" or "with the motor shaft horizontal"? From context we can assume the latter, but referring to the motor shaft orientation is unusual and should be called out if that's the reference for horizontal/vertical.
[ maybe it's about computer cases these days do not have a primary orientation for vertical | horizontal anymore (vs. previous cases with optical drives, having a main orientation wrt to cd/dvd/bluray drives loading mechanism or maybe still with liquid cooling these days) ]
In the olden days, or for old timers who dislike some modern case designs, computer cases often had a direct out-draft at the top of the case, often used by liquid coolers. My old case has two or three input fans and one output on the rear, and two on the top. When I had a liquid loop, I had radiators at the front and top.
I still think many old cases are better than current offerings (case labs, for example).
It's the same for many liquid-bearing fans: horizontal airflow only.
I'm using old classic GentleTyphoon with ball bearings because they can be mounted for vertical airflow without issues. I mounted them with sleeves for vibration damping, which greatly reduced noise. Most modern fans have rubber corners or similar to reduce noise. I'm surprised that this Sunon Maglev fan doesn't seem to have any damping rubber parts at all.
I been a sucker alway for cheap cooling fans only to find out they are only one speed fans. I learn to buy only the highest price fans now, that are able to switch speeds based on CPU cooling needs.
Without having noise vs rpm it is really hard to compare these fans? Felt halfassed. It is always a balance between noise, cfm and static pressure and from the review it was not clear how to compare these fans.

So this would also be a good replacement for the fans on my air cooler? Rocking an ID cooling 224 xt.GeoffreyA - Friday, May 17, 2024 - link
A legendary fan company. I remember having a few in the early 2000s, one of which worked till 2019, when the computer was retired.esoel_ - Friday, May 17, 2024 - link

The comparison is in the final chart showing the dB(A) values of the various fans at different levels of flow obstruction.ballsystemlord - Friday, May 17, 2024 - link
Addendum: I mean the noise is at the bottom in a table in the fan description. The flow obstruction vs. air output is the actual meat of the chart.meacupla - Friday, May 17, 2024 - link
Does this fan use airflow channeling/focusing (eg silverstone air penetrator), or does it disperse the direction?ballsystemlord - Friday, May 17, 2024 - link
I really like maglev. Those types of fans are awesome!ballsystemlord - Friday, May 17, 2024 - link

Is there something you think is wrong with that passage? I'm not sure I follow.GeoffreyA - Saturday, May 18, 2024 - link
Front and back are vertical.GeoffreyA - Saturday, May 18, 2024 - link
Though it's right for airflow direction.FrankSchwab - Saturday, May 18, 2024 - link

Well the issue relates to the motor axis direction so it's logical to refer to that.Ryan Smith - Monday, May 20, 2024 - link
That's fair. I've reworded the article to make it clear that we're talking about the direction of airflow. Thanks for the feedback!back2future - Sunday, May 19, 2024 - link

Yes, it does sound strange, unless you're talking about the direction of the air.Findecanor - Sunday, May 19, 2024 - link
