Not at all. I've got an air-cooled 1920X, which works just fine. Noctua makes good fans.
The downside is, a fan capable of cooling a 200W CPU is going to be huge; mine only has a few millimeters of clearance, and that's in an EATX case. AIO water-cooling is easier to fit.
Same here with a 1950X. I use a Noctua NH-U12S and it usually operates around 45-50C with a few VMs and a IDE running. Mine is crammed into an old SUN Ultra 24 case with a few mm's to spare.
Is that at base speed? I just recently got the parts for a 3900X build and while I orginally went for air cooling I switched out for a liquid cooler last minute worried about overclocking temps
I assume anything that's rated for 250watts will work fine with these chips. Probably not ideal for overclocking, but if your case has decent airflow you'll be fine.
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!
The AMD TDP number are much closer to real world figures compared to Intel which is pretty much an imaginary number that is only valid at its base clock.
Just a word of caution. Although this is generally true at the moment, AMD's definition of TDP has nothing to do with electrical power or heat output. It's just a marketing number that happens to come close to electrical power. Here's a very good source if you want details: https://www.gamersnexus.net/guides/3525-amd-ryzen-tdp-explai...
