how many mm?

will a 360 mil aio be able to keep an i9 12900k from overheating if the ambient temperature is about 30 to 40 degrees c ?

No. If you lower the power limit, maybe, but if you're gonna lower the power limit you might as well go for a 12700k instead. With that high of an ambient, a 360m AIO is probably the minimum you can get to keep a 12900k cool, and a 420mm would probably be advisable.

Even a 280mm cooler would be fine provided he's not running benchmarks all the time. The chip is toasty, but if he's gaming, considerably less so.

It really depends on what you mean by "overheating." If you mean "will it avoid thermal throttling?" then the answer is almost certainly "yes" if the mounting hardware is good for LGA 1700. If you mean "will it stay below 70C?" then "no," with 40C ambient you are probably going to be around 90C.

I'd recommend at least a 360mm AIO if you'll be using a 12900K in 40C conditions. However, the most important thing is to make sure it is designed to be used with the LGA 1700 socket mounting system. Buy a current generation AIO made specifically for 12th gen Intel, not an old one made for previous generations, unless you can find reputable reviews that say it works well with 12th gen.

I’ll just get the lian li Galahad off Newegg, I believe it is compatible
