The 3950X is suggested to use with a liquid cooler, but I would be amazed if one of the dual tower coolers like the Dark Rock Pro4 or Noctua DH15 didn't work fine in a case with good airflow.

threadrippers don't require liquid cooling, they have a larger heat spreader and lower peak clocks so heat is more manageable.

The 3950X has the same TDP as a 3900X. Both should be fine with good air coolers. I recently built my first new desktop system in years: A 3900X with a Dark Rock Pro 4 - in a slightly more spacious Mini ITX case (Lian Li TU150). Works great!
