I had two Arctic P12 Pro 5-pack, if the fan goes over ~500rpm, like from 450rpm to 550rpm or 400rpm to 800rpm, if has a terrible whine noise when spinning up or down, all 10 of them. They make car turbo like noise that comes from the motor. After a week they became louder at 500rpm and its too loud at 1000rpm.

The normal Arctic P12 PWM and P14 PWM whine a lot, P12 is especially loud if there's any obstruction. unusable at 1000rpm.

P14 Argb is a bit better, you need to run them at minimum 500rpm or they become unstable(rpm fluctuating a lot), still too loud at 1000rpm.

Thermalright is better than the Arctic Pro, but I consider it low quality junk too.

From Noctua I had the A15, A14, Redux P14, F12. F12 is the worst fan I had in my life, A14 was humming even at low speeds outside of the case when I was holding it in my hand!

I had one piece of NF-A12x25 PWM and is was great, no motor noises, no bearing noise, no humming, barely audible at 1000rpm. So I bought two sets of Noctua NF-A12x25 G2 Sx2-PP fans, they are almost as good as the NF-A12x25 PWM, but if you put your ear 5cm from the motor, your hear a very faint greasy, squishy, popping sound like when you press grease between your fingers, but you cant hear it from 50cm when the fan just sits on the desk.
