To not much surprise, the Noctua heatsinks did a great job cooling the AMD EPYC 8534P flagship Siena processor. The two heatsinks both allowed the EPYC 8534P to operate noticeably cooler than the Dynatron A54 heatsink, which is smaller for being able to fit within 2U height requirements. The Dynatron A54 during the 14+ hours of varying benchmarks ran with a 63 degree average and 87 degree peak. Both of the tested Noctua heatsinks led to a 41~42 degree average and a ~64 degree peak. The Noctua NH-U14S TR5-SP5 did perform slightly better than the NH-D9 TR5-SP6 4U due to the slightly larger size and larger fans, but overall both heatsinks worked great for cooling the AMD EPYC 8004 series 64-core processor. [...] For those building a workstation or server where noise is important, both of these Noctua heatsinks were very quiet during operation. Even at load these PWM fans were quite quiet as we've come to love with Noctua cooling... Certainly much better than Dynatron heatsinks and other conventional server cooling. The build quality of these Noctua heatsinks were also wonderful as always for Noctua products. About the only downside is that these Noctua heatsinks are expensive at $120~130 USD.

"If you are looking for a heatsink fan for cooling an AMD EPYC 8004 series processor or upcoming Threadripper 7000 series, the NH-D9 TR5-SP6 is a great option if looking to fit within 4U height requirements or otherwise a small chassis. If building a larger server or workstation with 5U or a tower, the Noctua NH-U14S is quite large and it will be interesting to see how its performance pans out with the Threadripper 7000 series that go up to a 350 Watt TDP."
