With the Blender 3D modeling software it's highly threaded and does make wonderful use of all 64 CPU threads. Still here the NH-U9 TR4-SP3 and its larger siblings had no troubles keeping up with cooling the EPYC processor.

The same goes with 7-Zip....

Even when loaded up with John The Ripper password cracker using OpenMP multi-threading across all available cores/threads, the EPYC 7551 with these heatsinks were reporting temperatures under 60 degrees.

Lastly is a look at the EPYC 7551 temperature with the different Noctua cooling configurations across a wide spectrum of tests conducted via the Phoronix Test Suite. All three TR4-SP3 heatsinks had no problem keeping cool the EPYC 7551 and thus shouldn't have any issues with any of the other EPYC processors nor the Threadripper CPUs. The NH-U9S TR4-SP3 in the Threadripper 1950X system continues running excellent and since this EPYC processor comparison have continued using the NH-U9S TR4-SP3 to cool the EPYC 7551 and throughout the dozens of hours of benchmarks run, have not encountered any situation yet where it's running into any reported thermal throttling or where the k10temp driver even reports a temperature above 60 degrees.

Thanks to Noctua for supplying these review samples and those interested in these Threadripper/EPYC heatsinks can find them stocked at the likes of NewEgg. The NH-U9 TR4-SP3 currently retails for $69 USD while the NH-U12S TR4-SP3 is priced about the same and then the mighty large NH-U14S TR4-SP3 is retailing for $79 USD.
