Noctua NH-D9 DX-3647 4U: A High-End Xeon Scalable Heatsink

Back in March we looked at the cooling performance of Noctua's AMD EPYC heatsinks for cooling these Zen-based server processors. The Noctua heatsinks tested did a wonderful job testing those socket SP3 processors so when the Austrian company announced a few weeks ago their Xeon Scalable heatsink line-up, we decided it would be interesting to see how their latest Intel server heatsinks perform.
