Dynatron A38 Active CPU Cooler 2U for Socket SP3, sTRX4, TR4, sWRX8

The Dynatron A38 is a high-performance active CPU cooler designed for 2U rackmount servers and workstations. It supports AMD EPYC and Ryzen Threadripper processors on sockets SP3, sTRX4, TR4, and sWRX8, with a TDP capacity of up to 280W. Featuring a copper base and aluminum fin heatsink, this cooler ensures efficient heat dissipation. The 80mm dual ball bearing fan operates at speeds from 1500 to 5000 RPM, delivering airflow between 15.0 and 50.0 CFM while maintaining noise levels from 18.0 to 48.0 dBA. The 4-pin PWM connector allows for precise fan speed control. Thermal paste is pre-applied for easy installation.

Advantages
