Socket and Material Differences
Socket Compatibility
You must match the cooler to your processor socket. The Dynatron Threadripper and EPYC CPU Cooler supports sTRX4, TR4, and SP3 sockets. This makes it suitable for AMD Threadripper and EPYC workstations. The Dynatron 1U AM4 Copper Passive Heatsink supports only AM4 sockets. It is designed for AMD Ryzen processors. If you use a Threadripper or EPYC system, the A39 is the only option. If you have an AM4 Ryzen build, the A37 fits. You cannot swap them between these distinct platform families.
Cooling Method
Active cooling provides consistent performance under load. The A39 uses a fan for active cooling. It handles up to 280W TDP. This allows it to manage high heat output from powerful CPUs. The A37 is a passive heatsink. It has no fan. It relies on case airflow to dissipate heat. Passive coolers work best in systems with strong airflow or lower TDP CPUs. The A39 offers higher cooling potential for demanding tasks. The A37 suits low-power or server environments with forced airflow.
Heatsink Material
Material choice affects thermal conductivity and weight. The A39 uses an aluminum heatsink with embedded heatpipes. Aluminum is lightweight and offers good thermal properties. The heatpipes help spread heat from the base to the fins. The A37 uses solid copper. Copper has higher thermal conductivity than aluminum. It absorbs heat quickly from the CPU. However, copper is heavier. The A39 is lighter at 1.65 pounds. The material difference means the A39 spreads heat via pipes, while the A37 absorbs it directly through copper mass.
Tower Design
Physical dimensions impact case compatibility. The A39 measures 4.7 inches in length, 3.2 inches in width, and 4.3 inches in height. It is a taller tower design. It requires clearance for the fan and fins. The A37 measures 5 inches in length, 3 inches in width, and 1 inch in height. It is a low-profile 1U server heatsink. It fits in tight spaces where height is limited. The A39 needs more vertical space. The A37 is ideal for compact server racks or small form factor cases with height restrictions.
Thermal Grease
Pre-applied thermal paste simplifies installation. The A39 comes with pre-applied Shin-Etsu 7762 thermal grease. This high-quality paste ensures good initial contact between the cooler and CPU. It saves you from buying separate paste. The A37 data does not mention pre-applied thermal grease. You may need to apply your own paste if it is not included. The A39 offers a more complete out-of-the-box solution for installation. The A37 might require extra steps or materials for optimal thermal transfer.
Which MITXPC Dynatron Model Fits You
Threadripper or EPYC workstation users
You need active cooling for high-power processors. The Dynatron Threadripper and EPYC CPU Cooler handles up to 280W TDP. It includes a fan and uses aluminum with embedded heatpipes. This model supports sTRX4, TR4, and SP3 sockets. It measures 4.7 by 3.2 by 4.3 inches and weighs 1.65 pounds. The pre-applied Shin-Etsu 7762 thermal grease simplifies installation for your specific socket.
AM4 server builds requiring passive cooling
You are building a 1U server with an AM4 Ryzen processor. This passive heatsink relies on case airflow rather than a fan. It is made of copper for efficient heat transfer. The compact 5 by 3 by 1 inch design fits tight chassis. It is designed specifically for AM4 sockets. This option removes fan noise and moving parts from your system.
Users needing compact fanless AM4 cooling
You require a low-profile solution for an AM4 system. The Dynatron 1U AM4 Copper Passive Heatsink offers a 1-inch height. This allows it to fit under standard 1U server constraints. The copper material provides direct heat conduction. It does not include a fan, so you must ensure your server case has adequate intake airflow. It is a silent, maintenance-free choice for steady loads.

Frequently asked questions
Does the Dynatron A39 support AM4 sockets?
No, the Dynatron A39 does not support AM4 sockets. It is designed specifically for SP3 and Socket SP3 interfaces. This makes it suitable for Threadripper and EPYC processors. If you need AM4 compatibility, you should consider the Dynatron A37 model instead. The A39 focuses on high TDP cooling for workstation-grade CPUs rather than mainstream desktop sockets.
Is the Dynatron A37 an active or passive cooler?
The Dynatron A37 is a passive cooler. It does not include a fan or any active cooling components. This design prioritizes silence and relies on case airflow to dissipate heat. It is best suited for low-power AM4 CPUs in 1U server cases where adequate airflow is available. Active cooling requires the A39 model with its included fan.
What material is used in the Dynatron A37 heatsink?
The Dynatron A37 heatsink is made of copper. Copper provides excellent thermal conductivity for passive cooling applications. This material choice helps dissipate heat from low-power AM4 processors effectively. The A39 model, by contrast, uses aluminum with embedded heatpipes for active cooling. Material selection depends on your specific cooling method and processor power requirements.
Can I use the Dynatron A39 in a 1U server case?
The Dynatron A39 is not designed for 1U server cases. Its dimensions are 3.2 inches wide, 4.3 inches high, and 4.7 inches long. This height exceeds the 1U form factor limit of 1.7 inches. The Dynatron A37 is specifically built for 1U systems. It has a height of only 1 inch, making it the correct choice for compact server builds.
Which model is better for high TDP processors?
The Dynatron A39 is better for high TDP processors. It includes a fan for active cooling, which is necessary for chips with high thermal design power. The A37 is a passive copper heatsink meant for low-power CPUs. Active cooling provides the thermal headroom required for Threadripper and EPYC workstations. Passive cooling may not suffice for high-power chips.
What is the weight of the Dynatron A39?
The Dynatron A39 weighs 1.65 pounds. This weight reflects its aluminum construction and embedded heatpipes. The A37 does not list a weight in the provided data, but it is a smaller passive unit. The A39 is heavier due to its active cooling components and larger surface area designed for high-performance workstations.
Does the Dynatron A37 come with a fan?
No, the Dynatron A37 does not come with a fan. It is a passive heatsink that relies on external airflow. The product attributes list cooling method as passive and features do not include a fan. You must ensure your server case provides sufficient airflow to cool the copper heatsink effectively without active assistance.
