AMD Genoa SP5 320W cooler

The Dynatron J12 is an active air cooler built for AMD Genoa processors on the SP5 socket. It uses heatpipes with an aluminium fin stack and a copper heat spreader on an aluminium base to handle up to 320W TDP. The unit fits 2U server chassis and taller enclosures. Shin-Etsu 7762 thermal grease comes pre-applied on the cold plate.

2U clearance with pre-applied paste

Installation follows the standard SP5 mounting pattern used in 2U and larger servers. The pre-applied Shin-Etsu 7762 compound removes the need for separate paste application and reduces the risk of uneven coverage. Builders must verify that the 4.7 by 3.6 by 4.1 inch envelope clears memory modules, VRM heatsinks and chassis side panels in their specific system.

Sustained 320W dissipation in server airflow

Under continuous load the copper spreader and heatpipe array move heat into the aluminium fin stack where forced airflow from system fans carries it away. The cooler is rated for 320W TDP in environments that maintain front-to-rear airflow typical of rack servers. Systems with restricted airflow or lower fan speeds will see higher steady-state temperatures. Buyers needing liquid cooling or support for sockets other than SP5 should look elsewhere.

Questions about this item

How do I verify the Dynatron J12 is cooling my AMD Genoa processor correctly after installation?

Monitor CPU temperatures under load using system monitoring software; the cooler is rated for 320W TDP so temperatures should remain within the processor's specified limits during sustained workloads.

What components are included with the Dynatron J12 and is any additional thermal paste required?

The package includes the copper heatpipe heatsink with aluminum fin stack and pre-applied Shin-Etsu 7762 thermal grease on the base, so no separate thermal compound is needed for initial installation.

Which Dynatron J12 variant should I select for a 2U server build with an SP5 socket CPU?

The J12 model is designed for 2U and taller server chassis, supports Socket SP5 processors up to 320W TDP, and measures 4.7 x 3.6 x 4.1 inches to fit standard 2U clearance.
