Output Noise
I use a Class 1 Bruel & Kjaer 2270 G4 sound analyzer equipped with a Type 4955a microphone with a dBA-weighted dynamic range of below 6 dBA and up to 110 dBA. All tests are conducted inside a hemi-anechoic chamber with a noise floor close to 6 dBA and an ambient temperature of 25–28 °C. The test subject is placed a meter from the sound analyzer.
Full & 70% Speed

The output noise is relatively low at full speed, and above the average at 70% of the fan’s maximum speed.
Speed (Percentage) – Noise
I use a different setup to drive the fan for noise measurements, so there might be a difference in the readings of the Longwin machine, especially in the max fan speed reading.

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
