At work a couple of years ago, we built two computers for the science
people with dual 16-core AMD CPUs and there was no special cooling
needed for those.
There are benchmark results for a 32-core / 64-thread AMD Threadripper 2990WX
"Besides the Cooler Master Threadripper heatsink, AMD also included the Enermax Liqtech TR4 240 with
the Threadripper 2 review hardware." The Enermax ran consistently cooler through the benchmarks.
There are plots of temperature over time that show all the coolers recovered quickly between
iterations, but many of them showed a rising trend for the duration of the benchmark. If you know
your workload provides some idle periods then air-cooling seems practical. If you do have the
odd large task then thermal throttling will slow it down, but that may be an acceptable trade-off
for a built-by-user system.
Hardware vendors have to configure for demanding workloads heavy on both I/O and CPU and
include the heat from a caseload of high-end HDD's. SSD's help to reduce overall cooling
requirements.
Liquid cooling generally simplifies airflow design issues. The big vendors can afford lots of
testing and custom air ducts, etc. that you don't get with the average user build.
