The Dynatron A31 is a 1U active CPU cooler engineered for AMD EPYC SP3 socket processors. It’s the direct predecessor to the Dynatron A41, featuring nearly identical design, mounting pattern, and performance. Built with a solid copper heatsink, densely packed aluminum fins, and a high-speed dual-ball bearing blower fan, the A31 provides reliable thermal control for rackmount servers and workstation systems running EPYC 7001, 7002, and 7003 series CPUs.
