Dynatron A47 Active Cooler for 2U Server & up for AMD® Socket AM4 AM5

Dynatron A47 — Active Server Cooler

For high-performance server environments, efficient processor cooling is key. The Dynatron A47 is an active cooler designed for 2U and larger servers that supports AMD® Ryzen processors with AM4 and AM5 sockets. Thanks to the combination of 4 heat pipes and aluminum fins, it efficiently dissipates heat, ensuring reliable operation at maximum processor load with heat dissipation of up to 145 W. The compact dimensions (107 x 78 x 67 mm) allow for easy integration even into limited server cabinet spaces.

Performance and Cooling

With a 60 x 60 x 25 mm fan with PWM speed control, the Dynatron A47 offers flexible performance tailored to current needs. The fan reaches speeds of up to 11,000 RPM at maximum load, providing high airflow of 58.31 CFM and maximum pressure of 28.8 mm-H2O. This is ideal for reliable cooling of processors in environments with high component density.

Low noise and reliability

Even at high power, noise is kept at an acceptable level. At low load, the fan generates only 25.8 dBA, which is suitable for environments where quiet operation is important. The double ball bearing ensures long life and reliable operation even in continuous operation.

Technical details for compatibility

• Fan power: 12V
• Power:
• 20%: 0.84 W
