As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Dynatron B13 2U Active CPU Cooler offers a compact aluminum heatsink with embedded heatpipes and a 60mm fan. It includes pre-applied Shin-Egetsu 7762 thermal paste and weighs just one pound. This design suits users who need a dedicated active cooler for tight 2U server chassis. You might look for dynatron 2u active CPU cooler alternatives if your build requires a different socket compatibility or a passive cooling approach. Some servers benefit from silent operation without fans, while others need support for specific AMD EPYC or Intel Xeon processors. The options listed here were chosen because their specifications overlap with the original product. Each alternative maintains the 2U form factor or active cooling method, ensuring they fit similar server environments. You can compare these picks based on their material, fan size, and socket support. This guide helps you find a unit that matches your hardware requirements without compromising on server height or cooling efficiency.
Comparing Alternative 2U Coolers
Dynatron 2U Active Aluminum SP3 Heatsink
The Dynatron A26 targets AMD EPYC SP3 sockets, whereas the B13 lacks specific socket data. This unit measures 4.5 by 6 by 5 inches, making it larger than the B13’s 3.15 by 2.6 by 4.25 inch footprint. It shares the same one-pound weight and aluminum construction. You should choose this if your server requires SP3 compatibility. It sacrifices the compact form factor of the B13 for broader socket support. Both remain active 2U coolers, but the A26 is built for different processor architectures. It does not support consumer desktop CPUs, limiting its use to server environments.
Dynatron 2U Active CPU Cooler
The Seasonic-branded B13 matches the original Dynatron B13 in every listed specification. Both share identical dimensions of 3.15 by 2.6 by 4.25 inches. They both serve as active 2U coolers for server racks. The primary difference is the brand badge, not the hardware specs provided. You might pick this version if you prefer Seasonic branding for your server build. The cooling performance should be equivalent since the physical dimensions and active cooling method are the same. It offers no size advantage over the original Dynatron unit. Choose this only if brand preference matters to your specific procurement requirements.
Sunydog LGA 2011 2U Active CPU Cooler
The Sunydog cooler supports LGA 2011 sockets, a specific compatibility the B13 does not list. This makes it suitable for Intel Xeon E5 platforms. The B13 is a general 2U active cooler without specified socket constraints in the data. You should select the Sunydog unit if your server uses LGA 2011 processors. It provides direct compatibility for that specific architecture. The B13 may require additional mounting hardware or lack the specific retention mechanism for LGA 2011. This alternative is best for users with Intel server chips needing active cooling in a 2U chassis. It trades the B13's unspecified versatility for targeted Intel support.
Dynatron B12 2U Passive Aluminum Cooler
The Dynatron B12 uses passive cooling, removing the 60mm fan found in the B13. This eliminates fan noise, making it ideal for noise-sensitive environments. However, it relies entirely on case airflow for heat dissipation. The B12 weighs 1.3 pounds, slightly more than the B13’s one pound. Its dimensions are 2.52 by 3.54 by 3.54 inches, differing from the B13’s shape. You should choose this if silence is your priority and your server has strong airflow. It gives up active cooling reliability for quiet operation. It is not suitable for high-heat scenarios without adequate chassis ventilation. This is a trade-off between noise and guaranteed active heat removal.
MITXPC Threadripper EPYC Passive 2U Heatsink
The MITXPC heatsink is a passive solution for AMD Threadripper and EPYC SP3 sockets. It lacks a fan, relying on server airflow like the B12. Its dimensions are 3.15 by 2.52 by 4.45 inches, similar in width to the B13. You should pick this if you need passive cooling for AMD high-end processors. It sacrifices active cooling performance for silence. The B13 uses a 60mm fan for active dissipation. This alternative is best for airflow-optimized server racks. It does not support Intel sockets. Choose this for specific AMD builds where noise reduction is more critical than active fan-driven cooling capacity.
Goshyda 2U Active LGA2011 Server Heatsink
The Goshyda cooler supports LGA 2011 sockets, targeting Xeon E5 2600 series processors. It includes a fan for active cooling, similar to the B13. The listed dimensions of 0.39 inches seem to be a single metric, likely height or thickness, rather than full volume. The B13 has clear 3D dimensions. You should choose this if your server uses LGA 2011 chips. It provides high fan speed for stable operation. The B13 is a more general 2U active cooler. This unit is specialized for Intel Xeon platforms. It offers active cooling for specific legacy server hardware. Pick this for LGA 2011 compatibility rather than the B13's unspecified socket support.

Frequently asked questions
Does the Dynatron B13 support AMD EPYC sockets?
No, the Dynatron B13 does not list AMD EPYC socket compatibility in its specifications. It is designed as a compact active cooler for general 2U server builds. For AMD EPYC SP3 processors, you should consider the Dynatron A26, which explicitly supports that socket type while maintaining the 2U form factor.
What is the weight of the Dynatron A26 heatsink?
The Dynatron A26 2U Active Aluminum Heatsink weighs one pound. This lightweight design helps reduce stress on the server motherboard. It measures 4.5 by 6 by 5 inches, making it larger than the B13 model, but still fits within standard 2U chassis dimensions for AMD EPYC systems.
Can I use the Dynatron B12 for an AMD processor?
The Dynatron B12 is described as a solution for Intel-based 2U servers. It is a passive cooler, meaning it relies on case airflow rather than a fan. If you need active cooling for AMD Threadripper or EPYC, the MITXPC passive heatsink or a dedicated active unit like the Goshyda might be more appropriate.
Which cooler is best for LGA 2011 sockets?
The Sunydog and Goshyda coolers are both designed for LGA 2011 sockets. The Sunydog model includes tool-included setup for specific server builds. The Goshyda unit features a fan for high-speed active cooling, making it suitable for Xeon E5 2600 series processors that require consistent airflow in a 2U environment.
Is the MITXPC cooler an active or passive design?
The MITXPC heatsink is a passive cooling solution. It does not include a fan, relying instead on the server chassis airflow to dissipate heat. This design prioritizes silence and reliability, making it ideal for users who need to cool AMD Threadripper or EPYC processors without generating additional noise from moving parts.
Do any of these coolers include thermal paste?
The Dynatron B13 comes with pre-applied Shin-Egetsu 7762 thermal paste. This saves you the step of applying paste yourself during installation. Other models in this list do not specify included thermal compound in their published attributes, so you may need to source your own paste for those units.
What are the dimensions of the Dynatron B13?
The Dynatron B13 measures 3.15 inches in width, 2.6 inches in height, and 4.25 inches in length. These compact dimensions allow it to fit into tight 2U server racks. It weighs one pound, offering a lightweight profile that minimizes load on the server motherboard while providing active cooling.
