MITXPC Dynatron 1U AM4 Copper Alternatives: 6 Similar Picks Compared

How alternatives compare to this cooler

SilverStone 1U Passive Copper Server Heatsink

The SilverStone 1U Passive Copper Server Heatsink targets Intel LGA2011 and LGA2066 sockets instead of AM4. It measures 3.54 by 3.54 by 1.02 inches and weighs 1.08 pounds. This cooler uses a square base design, which differs from the rectangular footprint of the Dynatron A37. It remains a passive copper solution suitable for silent 1U builds. However, it lacks AM4 compatibility, so it does not fit Ryzen processors. You should choose this if your system uses Intel Xeon or Core processors in a 1U chassis. It offers similar silent operation but requires a different socket support and slightly larger base area for heat distribution.

Dynatron 1U Copper Vapor Chamber Server Heatsink

The Dynatron B4A 1U Copper Server Heatsink features a vapor chamber for improved thermal transfer. It supports Intel FCLGA 3647 Narrow ILM sockets, not AMD AM4. The dimensions are 4.2 by 3.1 by 1 inches, and it weighs 1.06 pounds. This vapor chamber technology allows for more efficient heat spreading compared to the solid copper construction of the A37. It is designed for high-end Intel Xeon Platinum or Gold processors in 1U server chassis. You should pick this if you need superior passive cooling for demanding Intel workloads. It gives up AM4 support but provides better thermal performance through its advanced vapor chamber design for compatible systems.

Dynatron 1U Copper Blower Heatsink

The Dynatron R13 1U Copper Blower Heatsink uses active cooling with a blower design. It supports Intel LGA2011 sockets and measures 4.06 by 3.15 by 1.1 inches. It weighs 1.04 pounds. Unlike the silent passive A37, this cooler requires fan airflow to dissipate heat. It is suitable for Intel server builds needing active cooling under 95 Watts. You should choose this if you prioritize cooling capacity over silence in narrow 1U cases. It gives up the zero-noise benefit but offers active thermal management for processors that generate more heat. The blower design directs air efficiently, making it a practical choice for Intel-based 1U server environments.

Dynatron 1U Passive Vapor Chamber Heatsink

The Dynatron R31 1U LGA2011 Passive Heatsink includes a vapor chamber and supports Intel LGA2011 sockets. It measures 5.2 by 2.4 by 4.5 inches and weighs 7.94 ounces. This cooler is designed for Narrow ILM LGA2011 systems with 165-watt dissipation needs. It differs significantly in shape and size from the rectangular A37, offering a taller profile. You should pick this if you need high passive cooling performance for Intel processors in tight 1U spaces. It gives up AM4 compatibility but provides reliable captive mounting and vapor chamber efficiency. The larger footprint allows for better heat spreading in high-TDP Intel server builds.

Dynatron 1U Active AM4 Copper Heatsink

The Dynatron A18 1U Active AM4 Copper Blower Heatsink supports AMD AM4 sockets like the A37. It uses active cooling with a blower design, measuring 5 by 3 by 1 inches. It weighs 1.1 pounds. This cooler prioritizes copper fins and low profile over silent operation. You should choose this if you need active cooling for AM4 processors in 1U server builds. It gives up the zero-noise benefit but offers better thermal performance for higher TDP CPUs. The active blower design ensures consistent cooling, making it suitable for users who cannot rely on chassis airflow for passive dissipation. It maintains the same socket support while changing the cooling method.

Dynatron 1U Passive Copper Heatsink

The Dynatron A25 1U Passive Copper Heatsink supports AMD EPYC SP3 sockets instead of AM4. It measures 4.4 by 3 by 1 inches and weighs 1.3 pounds. This cooler is designed for silent operation in AMD EPYC SP3 systems. It shares the passive copper construction and 1U height of the A37 but targets a different socket. You should pick this if your server uses AMD EPYC processors. It gives up AM4 compatibility but offers specialized cooling for high-end AMD server CPUs. The slightly longer length accommodates the SP3 socket requirements. It remains a silent solution for 1U chassis with adequate airflow for passive dissipation.
