For those building your own server around the new Intel Xeon 6 "Granite Rapids" or AMD EPYC 9005 "Turin" platforms and using DDR5-6000/DDR5-6400 memory (or the interesting MRDIMM-8000 memory with Xeon 6 P), one of the factors you need to be much more mindful about than in the past is that at least the initial generation of DDR5-6000+ memory is running much hotter than prior server memory. There's been guidance from Intel and AMD as well as sever vendors about the thermal considerations with DDR5-6000/DDR5-6400 and extra precautions. Here's a look at the DDR5-6000 thermals on a recent AMD EPYC 9655 Turin server build and then taming the DDR5 server memory modules using Corsair Vengeance Airflow Memory Cooling Fans.
