Dynatron A38 Performance For Cooling 280 Watt AMD EPYC CPUs
Right off the bat from the testing the Dynatron A38 was showing lower CPU operating temperatures under load...
Across the wide variety of single and threaded workloads tested, the Dynatron A38 was consistently showing lower operating temperatures than the Dynatron A26 and Noctua NH-U9 TR4-SP3 coolers for the AMD EPYC 7003 series processor.
Here is a look at the CPU temperature readings over than span of the 8+ hours running the 106 benchmarks under test on this AMD EPYC 7763 1P server. On average the Dynatron A38 had about an eight degree lower average core temperature than the two other heatsinks tested. The peak recorded temperature was also nine degrees lower than the other tested Socket SP3 server coolers.
The lower CPU temperatures though weren't significant enough in this case to alter the outcome of the benchmark results.
Those interested in seeing the CPU temperatures and results for the 106 benchmarks run on the AMD EPYC 7763 across the three server processor coolers, that data is on OpenBenchmarking.org.
As for the noise level when the Dynatron A38 ramps up to full speed it can obviously get fairly noisy but that wasn't too often or out of the ordinary compared to other high performance fans aiming for 2U servers and larger. So overall the Dynatron A38 has been working out fairly well so far for even cooling the top of the line AMD EPYC 7003 "Milan" processors.
