I read that ball bearing fans become significantly louder over their lifespan, so they’re deceptive in terms of noise. Is that true? Also, I read that if they’re dropped they can be ruined, so they’re more delicate than FDB fans. It seems like a no-brainer to exclusively use FDB fans in high-end PSUs. Ball bearing fans appear to be able to produce more static pressure than other fan types but since FDB fans apparently can be used in low-noise PSUs, it seems that that advantage isn’t enough to outweight the drawbacks.
With not high quality DBB fans yes this can be the case.
