So Asus is going to release a rev. 2 of this PSU with updated fan?
Or you just going to be lucky to get one with better fan?
This is so sluggish of Asus.
I was really hoping this PSU would be the one I would buy, instead of the FSP hydro ti pro 1000w.
They installed new fans, after we found this issue.
actually this unit has the improved fan.
So with the new fan, do you recommend this over the FSP hydro ti pro 1000w in terms of pure silence?
Nope
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.
