As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The mitxpc dynatron a34 amd threadripper alternatives list helps you find compatible cooling solutions for AMD Threadripper and EPYC systems. This original heatsink offers silent, passive cooling for servers under 180 watts. It fits standard 2U chassis with dimensions of 4.45 x 3.15 x 2.52 inches. You might want a different option if your case requires active fans or a lower 1U profile. Some builds need copper base plates for better thermal conductivity. Others may require active cooling to handle higher power loads beyond the passive limit. The alternatives in this guide were chosen because their specs overlap with the original. Each product supports relevant sockets like SP3 or sTRX4. We compare dimensions, materials, and cooling methods to match your specific server constraints. You can choose between aluminum or copper construction based on your thermal needs. Active or passive methods depend on your airflow capabilities. This selection covers various heights from 1U to 2U. It includes both fanless and fan-assisted designs. You will find options for different socket types and system heights. The goal is to help you pick the right hardware for your build.
Our top pick: MITXPC Threadripper EPYC Passive 2U Heatsink.
How each alternative compares
Dynatron 2U Active Aluminum SP3 Heatsink
The Dynatron A26 uses active cooling with a fan, unlike the original passive design. This allows it to handle higher thermal loads in systems with case airflow. It is slightly wider at 4.5 inches and taller at 6 inches. The aluminum construction keeps weight low at one pound. You should choose this if you need active airflow to manage heat in a 2U chassis. The original is better for silent operation where fans are not desired. This model sacrifices silence for increased cooling capacity through forced air movement.
Dynatron 1U Passive Copper Heatsink
This cooler fits in tight 1U server enclosures, whereas the original requires 2U height. It measures only one inch tall and uses copper for heat transfer. The copper base provides different thermal properties compared to the original aluminum base. It weighs 1.3 pounds and supports the SP3 socket. Choose this if your chassis limits height to one unit. The original offers more fin surface area due to its greater height. This option is for users needing silent operation in space-constrained 1U servers rather than standard 2U racks.
Dynatron 1U Copper Vapor Chamber Server Heatsink
The Dynatron A28 integrates a vapor chamber for efficient heat spreading. It is designed for 1U passive cooling, fitting under one inch tall. The copper construction and vapor chamber technology differ from the original aluminum stacked fin design. It weighs 1.01 pounds and supports the SP3 socket. Select this if you need low-profile silent cooling in a 1U system. The original is larger and lacks vapor chamber technology. This alternative prioritizes height reduction and advanced heat transfer materials over the larger surface area of the original 2U heatsink.
Dynatron B12 2U Passive Aluminum Cooler
The Dynatron B12 is designed for Intel processors, not AMD Threadripper or EPYC. It supports 2U passive cooling but lacks the specific socket compatibility of the original. Its dimensions are 3.54 by 3.54 by 3.54 inches. It weighs 1.3 pounds. You should only consider this if you are building an Intel 2U server. The original is strictly for AMD sockets. This product gives up AMD compatibility for a form factor suitable for Intel LGA platforms. It is not a direct alternative for Threadripper or EPYC users.
SilverStone 1U Passive Copper Server Heatsink
The SilverStone SST-XE01-2011 is built for Intel LGA 2011 and 2066 sockets. It does not support AMD Threadripper or EPYC processors. It is a 1U passive copper heatsink measuring 3.54 by 3.54 by 1.02 inches. It weighs 1.08 pounds. Choose this if you are using an Intel platform in a 1U chassis. The original is specific to AMD sockets and is taller at 2U height. This alternative provides silent copper cooling for Intel systems but is incompatible with the AMD sockets required for the original product.
Dynatron Threadripper and EPYC CPU Cooler
The MITXPC Dynatron A39 includes a fan for active cooling, unlike the original passive model. It supports the same AMD sockets: sTRX4, TR4, and SP3. It is taller at 4.3 inches and weighs 1.65 pounds. The active design helps manage higher TDP loads in 2U builds. Pick this if you need active airflow to cool high-wattage processors. The original is better for silent environments without fans. This model trades the silence of the original for enhanced thermal performance through forced air circulation, making it suitable for hotter AMD CPUs.

Frequently asked questions
Can I use a standard desktop CPU cooler with AMD Threadripper?
No, you need specialized server-grade heatsinks. The products listed here are designed for SP3, SP3r2, and TR4 sockets found in Threadripper and EPYC systems. Desktop coolers often lack the mounting hardware or height clearance required for these large server platforms and 2U chassis.
Which cooler is best for a silent Threadripper build?
The MITXPC Threadripper EPYC Passive 2U Heatsink is the best choice for silence. It uses a passive design with no fans, relying on case airflow to dissipate heat. This makes it ideal for users who prioritize quiet operation in 2U server environments.
Do I need an active cooler for high TDP Threadripper CPUs?
Yes, if your processor exceeds 180 watts, passive cooling may struggle. The MITXPC Dynatron A39 Active Air Cooler includes a fan to handle higher thermal loads. It supports SP3, TR4, and sTRX4 sockets, making it a practical option for active cooling needs.
What is the difference between copper and aluminum heatsinks?
Copper heatsinks, like the Dynatron A25 and A28, offer superior thermal conductivity and are often used in 1U passive builds. Aluminum options, such as the Dynatron A26, are lighter and cost-effective for active cooling. The material choice depends on your height constraints and airflow availability.
Are these coolers compatible with Intel LGA 2011?
Most listed options are for AMD SP3 sockets. However, the SilverStone SST-XE01-2011 is specifically designed for Intel LGA 2011 and LGA 2066 processors. If you are building an Intel server, this 1U passive copper heatsink is the only compatible choice in this list.
How tall are these server heatsinks?
Heights vary by model to fit different chassis standards. The 1U models, like the Dynatron A25, are approximately 1 inch tall. The 2U options, such as the Dynatron A26, are around 6 inches tall. Always check dimensions against your server case clearance.
Is a vapor chamber necessary for Threadripper cooling?
A vapor chamber is not strictly necessary but helps in tight spaces. The Dynatron A28 uses a copper vapor chamber to spread heat efficiently in a 1U passive design. This allows for effective cooling without a fan, provided your case has adequate front-to-back airflow.
