Still waiting for my 3080FE but here is some thoughts how it could be done:
- air cool your CPU for example BlackRidge, AXP90 or L9a + Fan Duct. If you have a high power CPU like 3900X limit it to 65W in UEFI. The 92mm AIO will add to much heat between PSU and GPU
- add a bottom 92 fan as intake to get fresh air between GPU and PSU
- remove the plastic sheet between GPU and PSU
- use a SFX-L like the "Fractal Design 650W" (ratet for ambient temp of 50°C) and flip it so the intake hole will face the back side of the psu.
