Choosing airflow for Lancool 207 build with AIO

Hi.

I'm struggling to choose the most balanced airflow for my new LianLi Lancool 207 build with top-mounted AIO.

Components are Ryzen 9950X3D OC'd (expected ~200-250W TDP, orange arrows) and ASUS 5090 (~600W TDP, red arrows).

My goal is to provide each component sufficient cooling, including RAM.

Option 1:

My first option is classical approach: front + bottom intake, back+top exhaust. My top concern here is that RAM will be blasted with hot air from a furnace 5090. Plus AIO will also get mostly hot air.

Option 2:

Second option is to use bottom for GPU intake, top for AIO+RAM needs and to exhaust hot air using front and back fans.

Option 3:

Third setup is a bit funky. Idea is to use bottom + front-bottom fans for GPU intake, back for AIO needs. Use top-front for exhaust. And then to use central AIO fan to provide RAM airflow. I won't sure this will work and won't recirculate hot air back into central AIO fan from top.

Any thoughts on what should I choose?
