Need Help Choosing Fans and a Case for My New PC Build

Hey folks,

I'm currently building a PC and I'm in a bit of a quandary when it comes to selecting fans and a case. I'm aiming for a dual-chamber case, but I'm unsure which fans (and models) would suit my needs best. Here are my main questions:

- Which fans are the quietest when my PC is both under load and idle?
- Which fans excel at pushing and pulling air?
- Which fans give off a clean white light (I'm aiming for a white build, but I might consider black if necessary)?
- Which fans are higher quality and more durable over time?
- Lastly, which fans look the best? I really want to avoid visible LEDs when the fan light is set to white.

As for cases, I'm considering the following dual-chamber designs:
- Lian Li O11 Dynamic
- NZXT H9 Elite or H9 Flow (2023)
- Corsair's dual-chamber case (though I've heard mixed reviews on the build quality)

I would love to hear about your personal experiences and recommendations for specific fan models, especially those that fit well with these cases.

Thanks a lot!
