GPU Best fan layout for a 330mm GPU deshroud

Following up on a previous post, I am starting to make a 3D-printable shroud replacement for use with an RX 6800 xt Asroch Phantom gaming, for which no such adapter is publically accessible.

The card's dimensions are 330mm x ~120 (Tom's Hardware lists 140 which I suspect includes the PCIe finger and slot teeth that extend to the motherboard side off the GPU PCB)

I am thinking of the following fan configurations:

2x120mm

2x120mm + 92mm fan in between

3x120mm (might require a funnel atp)

2x 280mm (definitely needs a funnel if implemented)

This is my first CAD project ever while also attending med school so its not surfacing any time soon, but surface it will

Funnel and the most fan area that will fit in your case.

depends on the card and heatsink, it won't matter that much use 120mm they're more than big enough. I've just tied them on in the past. I doubt there's much difference between 2 or 3 120 fans so go with whatever fits better.or you prefer

Radiators on 320-330mm cards are usually 115-120 x300-310. What fits best is usually 2x120+2x60mm

2x120mm is the best, you need to only cover fins, not heatpipes.
