Air flowrate for a new build

[lobez]

Hi everyone!

I have built lots of computers for friends and family. But now, it is my time! hehe

I am going to get a Fractal Design mid tower, and throw a EKWB Predator 360 AIO on it for CPU+GPU cooling. The 360 radiator will be mounted at the front, with 3x120mm fans intaking.
If I do so, only rear part and top part will be free to put some fans out-taking all the hot air. But if I want to mount fans at the top part, I have to remove the sound dampening plate; and I do not want to do so. I want this build to be very silent.
So, there is space for only one 120mm high flowrate noctua fan (yes, it has to be noctua ;-)).

Will that 120mm out-taking fan be enough to exhaust all the hot air pushed in by the predator?

Thanks in advance!

Which fractal design do you get? Most support a 140mm fan

Furthermore the top part sound dampening isn't nearly as good as the sides/front parts and do very little. Installing one fan top won't increase sound much.

Define C most likely. Only 120mm rear fan.
Removing the top part sound dampening is not a solution for me.

P.S. I want the smallest possible case.

360 AIO and smallest possible case ?
If you want positive pressure + good airflow, you would want at least 2x140 fans to match 3x120.
Else 3x120 exhaust @ less rpm + 3x120 intake @ more rpm.
Since you said silent as possible, i guess you can get another fan or two 120/140mm for exhaust.
Else a lot of hot air will stay inside the case most likely, which would make your WC kinda pointless.

Thanks for your reply.

I contacted EKWB customer support. They confirmed it will work just fine (predator360+1x120mm exhaust fan). It may cause +2/3ºC over having 2x120mm fans, but that's all.
