I would like to use a F.D. Meshify 2 XL case to house and cool my 3 GPUs plus my 5950X CPU

I want to water cool 3 GPUs plus a 5950X in a Fractal Design Meshify 2 XL. The 3 GPUs are 2 x EVGA 2070 Supers and an EVGA 3080 10GB FTW3.
My current plans are to use a 420mm x 60/64mm rad and a 360mm x 60mm rad with a combination of push/pull fans for each rad.
My systems, currently air cooled in two desktops, run at ~850 W to ~900 W combined. My calculations are approximate, but I think they are accurate enough.
Will this be enough cooling capacity for an ambient 84॰ F (29॰ C)?
If not, what do you suggest I use?

In push/pull mode with the thick radiators, this should work. However, a silent system is not to be expected there. I don't know if that's important to you?
