I cool a 3950x with a C7g with noctua fan swap in an A4 whilst i wait on my T1 to arrive and switch to 240mm water., prior to this i had a 1700 under an l9a.
the c7g is keeping ym 3950x cool enough for gaming and daily workloads and running a few VM's etc, I also have it in eco mode.
but if I smash it with say 2 bluray encodes and get the cpu up to 90% on all cores then it will thermal throttle after a while. it will turbo to 4ghz in gaming though as it only needs to boost 1-2 cores for this.
That said I do not recommend it, my setup has always been a palceholder cooling solution till i get a T1, a 3800x in eco mode or with SMT off (i don't know what your workloads are) and if you are willing to run the fans at 100% (i cap mine at 70% max for noise) then you would probably be fine, my 1700 on l9a never got over 75deg in 100% load in summer (32deg abient)
having additional case airflow that my Dan A4 has zero of would air a great deal as well, so air cooling with these LP air coolers would be more effective in the T1 than a Dan A4 for sure.
Strange thought. . .240mm air cooler with heat pipes to the cpu? would be 100% bespoke, but pretty cool, similar to the way Shuttle used to cool their old systems where they heat piped to a fin array on the exhaust of the case with a fan that was case exhaust and cpu cooler, kinda like a mini AIO but not an AIO. Worked really well for my skt939 AMD chip i had back then!
