I have a ATX case at the moment so I could, in theory, top mount a 360mm rad.
Currently my 120mm AIO rad sits at the back but, maybe top venting would give better air flow
I'm doing two front fans, aio out the top, one fan out the back and psu out the bottom.
The Noctua will be fine and make sure to use those rubber fan holders rather than screws cos they help the noise a lot.
This is the route that led me to buy a full size tower case for better airflow until it arrived and I realised it's nearly as tall as my desk.
