I'm debating between an O11D with an AIO (Probably Arctic II 360) or a Lancool II with air setup (DRP 4 or NHD15) so I guess you would lean towards the Lancool?
That said I have an existing O11D (not available for use in the new build) that is fully decked out with fans - they're Corsair QL series (I think) so big on looks, not so much on actual airflow but the internal temps stay pretty good. 3 bottom intake, 3 side intake, 3 top exhaust push/pull with an AIO.
An O11D or anything with a mesh front should be ok. I had problems with mine in an Asus Helios because the glass panel in the front was choking the air intake. Was getting over 70 on the core and low 100s on the vram causing the gpu fans to go into hoover mode (1700+ rpm). For reference the stock helios did about the same for thermals as my old Fractal define R4. Took the glass out and now it's essentially the same setup as a Phantek P500. With the case and AIO fans on a curve that tops out at 1100 the gpu fans stay under 1300 which is inaudible over the rest of the system.
The 3090FE is also prone to coil whine if you're pushing high FPS. Mine does it on the few games that I can push 4k >80 fps but it's bearable. If the prices and availabilty hadn't gone nuts I'd be looking at Asus Tuf, MSI Suprim and top end of the Zotac range.
If you're playing at 1440 and can work in 8gb would a 3070 be a cheaper option? I've got a 2080ti that I use for living room couch gaming at 1440. It works fine and it's a lot easier to run than a 3090.
