Dynatron J12 Active 3U Cooler for AMD SP5 socket up to 320W

Dynatron J12 — 3U Active Cooler for AMD SP5

In demanding server environments, efficient cooling is key to long-term performance and stability. Designed for high-performance AMD® Genoa® processors with SP5 socket, the Dynatron J12 can dissipate up to 320W of thermal power, which is essential for maintaining optimal operating temperatures under maximum load. The combination of aluminum fins, copper heat spreader and integrated heatpipes ensures fast and efficient heat dissipation. It is an ideal choice for servers with a height of 3U and above, where high power density is required.

Performance and cooling efficiency

With a 80 x 80 x 38 mm fan and variable speed (from 2400 RPM at low load to 8000 RPM at full power), the Dynatron J12 provides flexible cooling tailored to the current needs of the server. At maximum speed, it provides airflow of up to 115.61 CFM, which is sufficient to remove heat from even the most powerful processors. Low noise at lower loads (25.63 dBA) contributes to quiet operation, while at full power, the necessary aerodynamic efficiency is achieved.

Reliability and build quality

The Dynatron J12 cooler uses double ball bearings, which ensure long life and high resistance to continuous operation. The aluminum and copper combination construction optimizes heat transfer, while the pre-applied Shin-Etsu 7762 thermal paste facilitates installation and ensures maximum thermal contact between the cooler and the processor. The material processing and robust design guarantee consistent performance even in demanding data center conditions.
