A34 vs A39 Spec Breakdown
Cooling capacity
The Dynatron A34 is rated for up to 180 Watts of heat dissipation. This makes it suitable for lower power Threadripper or EPYC builds. The Dynatron A39 handles up to 280W TDP. This higher rating supports more powerful processors in the same socket lineup. If your CPU draws significant power, the A39 offers more headroom. The A34 may struggle with high-end chips under heavy load. Choose the A39 for demanding workloads.
Cooling method
The Dynatron A34 is a passive heatsink. It relies entirely on case airflow to move heat away from the fins. It does not include a fan. The Dynatron A39 includes a fan for active cooling. This ensures consistent heat removal regardless of case airflow patterns. If you need guaranteed cooling performance, the A39 is the better choice. The A34 requires a chassis with strong forced air. Passive cooling is quieter but less effective in stagnant air.
Physical dimensions
The Dynatron A34 measures 4.45 inches in length, 3.15 inches in width, and 2.52 inches in height. It is a low-profile 2U server heatsink. The Dynatron A39 measures 4.7 inches in length, 3.2 inches in width, and 4.3 inches in height. It is significantly taller. The A39 requires more vertical clearance in your chassis. The A34 fits in tight server racks or low-profile cases. Check your case height limits before choosing the larger A39.
Socket compatibility
Both coolers support the same AMD sockets. They work with sTRX4, TR4, and SP3. This covers AMD Threadripper and EPYC processors. You do not need to worry about socket mismatch between these two models. Both units use aluminum bases with heatpipes for heat transfer. The mounting mechanism is designed for these specific server-grade sockets. This shared compatibility means you can choose based on size and cooling needs rather than socket support.
Thermal paste
Both products come with pre-applied Shin-Etsu 7762 thermal paste. This is a high-quality thermal grease known for stability and performance. You do not need to buy separate thermal compound. The paste is applied to the base before installation. This saves time and ensures proper coverage. Both the A34 and A39 use the same formula. This shared feature simplifies the installation process for both models. You can trust the factory application for initial setup.
Choose your MITXPC cooler
Low power server builder
You need a compact passive solution for a 2U server chassis. The Dynatron A34 fits dimensions of 4.45 x 3.15 x 2.52 inches. It handles up to 180 Watts of heat dissipation. This capacity suits lower power Threadripper or EPYC processors. The pre-applied Shin-Etsu 7762 paste ensures reliable thermal contact without extra steps.
High performance workstation user
You require active cooling for high TDP processors. The Dynatron A39 supports up to 280W TDP with its included fan. Its larger size of 4.7 x 3.2 x 4.3 inches allows better airflow. The aluminum heatsink with embedded heatpipes moves more heat than the passive unit. This setup is ideal for demanding Threadripper or EPYC workloads.
Compact 2U enclosure builder
Space is limited in your 2U server case. The A34 is thinner at 2.52 inches compared to the A39's 4.3 inches. It uses a passive design, so it needs no fan clearance. This fits standard 2U height constraints perfectly. It supports SP3, sTRX4, and TR4 sockets. You get a quiet, low-profile cooling solution for moderate power CPUs.
