Noctua NF-F12 iPPC-3000 PWM - Fan Noise

https://noctua.at/en/nf-f12-industrialppc-3000-pwm

Overall I don't really like this fan. The design of the blades and the stator vanes - both being straight - means they basically become an axial rotary siren. So even at low speeds, you get a similar sound to mounting a typical 7-blade fan right up against a stamped grill. I think there are much better options nowadays if you want a high quality, high speed fan - Phanteks F120T30 comes to mind. And if you want IP67 ratings, get one of Sanyo Denki's IP68-rated Splash Proof fans, like the 9WV1212P1J001. The only real reason you might go for this over the Sanyo Denki is because that one is 38mm thick. So this Noctua does seemingly occupy the very specific niche of being 120x25mm and IP67+.
