SP5 cooler for Genoa servers

The Dynatron J10 is an active air cooler built for AMD Genoa processors on Socket SP5. It is designed for 2U server chassis and higher, targeting administrators who need reliable thermal management for dense compute nodes. Buyers needing liquid cooling loops or support for other socket types will not be served by this model.

Shin-Etsu 7762 paste included

Pre-applied Shin-Etsu 7762 thermal grease removes the need for separate compound application during installation. This saves assembly time and ensures consistent coverage across the heatspreader for immediate operation.

Copper heatpipes with aluminium stack

Heatpipes combine a copper base with an aluminium fin stack to move heat away from the CPU. The unit measures 4.7 x 3.6 x 2.6 inches, fitting standard 2U rail spacing while supporting up to 300W TDP dissipation.

Questions about this item

Will the Shin-Etsu 7762 thermal grease need to be reapplied later?

The Shin-Etsu 7762 compound is pre-applied and designed for long-term stability; replacement is only needed if the cooler is removed or after several years of continuous operation.

What thermal limit defines the maximum sustained load for this cooler?

The cooler is rated to dissipate up to 300W TDP; sustained loads above that level will exceed its heat-removal capacity.

How much heat and fan noise should I expect when it runs continuously in a 2U server?

At full 300W load the fan spins faster to move heat through the aluminum fin stack, producing noticeable airflow noise and warm exhaust air inside the chassis.
