Performance – Max & Speed Percentage
Max RPM, CFM, Pressure & Power

The maximum speed is high enough, but this is not true for the maximum airflow and static pressure. At least, power consumption is low.
10 – 100% Fan Speed Percentage
Since most fan control ICs don’t apply precisely the percentage of RPM speed that you want (e.g., 50% PWM for a 2000 RPM fan should be 1000 RPM), I used to find the fan’s maximum speed and then dial directly the fan speeds that corresponded to 10%, 20%, and so on of its maximum rated speed. I decided to stop doing that. So from now on, in all of my fan evaluations, I will dial the corresponding PWM value in 10% steps to also check how accurate its fan controller is, and for my noise results to align with the airflow and static pressure results from the Longwin apparatus, where I don’t use RPM but PWM control for all testing.

I highly doubt this fan has any sort of proper “FDB” bearing. Especially not at this price point. I’ve disassembled one C12B fan before and the claimed “FDB” was actually just a rifle bearing.
They’re just like Arctic in this matter.
True, real and proper “FDB” bearing with long endurance would by itself raise the cost by 15-20$, mainly due to the need of QA.
If you go after cheap fans, don’t expect them to last and your wallet will keep crying. Now, i’m not saying: “go for most expensive stuff”, i’d rather say: “manage your expectations”. The more you’ll keep buying these junk fans, the more e-waste will be created.
They provide a photo on the product page on Amazon of a true FDB.

I’ve love to see how the Fractal Momentum 12 and 14 fans fare. Are they really top-tier like other reviewers say?
I installed three Momentum 14 (without RGB) fans on the front of a Phanteks P600S and had to return them because they generated a very annoying buzzing noise below 900 rpm. It’s a shame because I was hoping they would be high-quality fans. I finally installed three Corsair RS140 Max fans and I’m delighted because they move a lot of air and if you keep them below 1000 rpm, they are quiet enough.
RS140 Max are top, but bloody expensive. You get at least what you paid for (or a part of it ok)
Will you test the new Arctic P14 Pro fans? They claim to have higher CFM and Static Pressure than P14 Max fans.
Yes
