SilverStone XE360-SP5 & XE04-SP5 For Cooling AMD EPYC 9004/9005 4U Servers

Among the early workloads tossed onto this Supermicro 1U EPYC Turin server build while testing both SilverStone SP5 coolers was Blender running across all 96 cores / 192 threads. The XE04-SP5 was running with a 67 degree average and 70 degree peak while with the AIO liquid cooler in the same conditions was a 58 degree average and 62 degree peak. But running in the 60s is no issue for the AMD EPYC SP5 processors and there was no difference in CPU performance between these coolers.

The XE360-SP5 had up to a ~15 degree advantage on average with its AIO liquid cooling compared to the XE04-SP5 heatsink fan. But as shown by the CPU performance results, the XE04-SP5 was still equally capable of cooling this 400 Watt EPYC server processor without thermal throttling / impacting the resulting performance.

With the Stockfish chess benchmark was one of the largest differences in performance at 20 degrees between these cooking options but still achieving the same level of performance on this AMD EPYC 9655 1P 4U server.
