I recently purchased a 7980XE motherboard, and I'm checking if it can reach 4.8GHz using the setup you described. I have several high-end components like EK 480mm and 240mm rads, Revo D5 pumps, Noctua fans, and a Copper Velocity 2066 block. I heard it's feasible with around 1.25V, but I want to confirm if this configuration will work. The price was about £680, so I'm curious about the cost-effectiveness of this build.

Testing is needed to confirm the chip's capabilities, but increasing radiators and fans doesn't boost maximum OC linearly. A key issue with X299 chips is reaching a limit where heat can't be removed fast enough from the silicon, keeping temperatures unsafe. This is the point I've reached with my 10980xe—it can run at 5GHz across all cores around 1.3V, but even at 1.23V it overheats quickly, with the hottest cores reaching 90°C almost instantly. Adding more radiators in a case won't prevent this with ambient cooling.

I hope I could obtain 10980XE, but it's not available anywhere unfortunately.

Your 7800X with LM and water setup can handle 4.9, reaching about 5.0 with chilled water. Keep in mind this is for non-AVX tasks like Cinebench R15, and you may need significant AVX extension.

Direct die cooling could provide a bit more margin for error.

I haven't attempted it yet, but I'm curious—did someone else handle this before?

Jayztwocents achieved a 4.9 GHz stable Cinebench score once. You can view it on YouTube.
