Thelio intake fan produces annoying sound on spin-down #55

The be be quiet! 14025-hf-pwm fan that Thelio uses for its intake is quite noisy, particularly when spinning down. It produces an audible "rattly" noise. I uploaded a video below. Not all speakers seem to reproduce the noise well, so.. headphones recommended I guess? I promise it's much more audible in real life! Some times are louder than others. I'm probably going to end up replacing the fan on my Thelio. I experienced the issue on another Thelio so I know it's not just a one-off defect.

I ended up replacing the fan with a Noctua NF-A14. This fan moves more air but is also, on paper, louder. However, it's still very quiet to my ear, even with the case panel off and in a quiet house with a low noise floor. In addition, it does not produce the "rattling" noise that the be quiet! fan does. The cable is also an appropriate length for connecting to Thelio IO.

I've been having the same problem with my fans
