How these options differ
Dynatron Threadripper and EPYC CPU Cooler
The MITXPC Dynatron A39 uses an aluminum heatsink instead of copper, which changes thermal conductivity properties. It supports the same SP3 socket but reaches a 280W TDP rating, offering more headroom than the 225W limit of the Inter-Tech A41. The physical dimensions are slightly different, with a height of 4.3 inches compared to the 1.12-inch profile of the original. This taller design sacrifices the low-profile 1U form factor for greater surface area. You should choose this if you need higher thermal capacity and have the vertical space in your chassis. It remains a practical choice for budget builds requiring reliable active cooling for high-power Threadripper or EPYC processors.
Dynatron 3U Socket SP3 Heatsink Fan
The Dynatron A50 is designed for 3U server chassis, making it significantly taller at 4.33 inches than the 1.12-inch Inter-Tech A41. It supports the SP3 socket and handles 280W TDP loads, providing better thermal management for high-power CPUs than the 225W rated original. The increased height allows for a larger heatsink mass, which improves heat dissipation in rack-mounted environments. You must ensure your server case has the necessary vertical clearance to accommodate this 3U profile. This option is ideal for users who prioritize cooling performance over compactness. It delivers adequate active cooling for demanding SP3 systems where space constraints are not a primary concern.
Dynatron 1U Passive Copper Heatsink
The Dynatron A25 is a passive copper heatsink, meaning it lacks an integrated fan unlike the active Inter-Tech A41. It maintains the 1U height of 1 inch, fitting into the same low-profile space. The copper material provides good thermal conductivity, but without forced airflow, it relies entirely on case fans for heat removal. This makes it suitable only for chassis with high static pressure and airflow. You should pick this if you require silent operation and have a server environment with robust cooling. It sacrifices active cooling efficiency for zero noise, making it a specialized choice for passive EPYC SP3 servers where acoustic performance is critical.
Dynatron 2U Active Aluminum SP3 Heatsink
The Dynatron A26 is a 2U active aluminum heatsink, differing from the 1U copper original in both height and material. It stands 6 inches tall, requiring significantly more vertical space than the 1.12-inch A41. The aluminum construction offers different thermal properties compared to the copper vapor chamber base of the Inter-Tech model. It supports the SP3 socket and provides reliable active cooling for 2U server builds. You should choose this if your chassis is a 2U rackmount unit and you need robust thermal management. It is not suitable for 1U cases. The larger size allows for effective heat dissipation in standard 2U server environments using AMD EPYC processors.
Dynatron 1U Copper Vapor Chamber Server Heatsink
The Dynatron A28 is a 1U copper heatsink featuring a vapor chamber, similar to the Inter-Tech A41. However, it is a passive unit without an integrated fan. It matches the 1U height constraint at 1 inch, fitting into the same low-profile space. The copper construction and vapor chamber base provide dense heat dissipation for SP3 EPYC chips. You should select this if you need a low-profile solution but can rely on case airflow for cooling. It gives up the convenience of an included fan but offers silent operation. This option is best for builders who prioritize low height and passive copper performance in 1U server racks with adequate external airflow.
MITXPC Threadripper EPYC Passive 2U Heatsink
The MITXPC A34 is a passive 2U heatsink designed for 180W TDP systems. It is significantly taller at 2.52 inches than the 1.12-inch Inter-Tech A41. It supports the SP3 socket but lacks an active fan, relying on case airflow for cooling. This makes it unsuitable for standard desktop builds or higher power requirements. You should pick this if you need quiet, low-profile cooling for 180W Threadripper or EPYC systems in a 2U chassis. It sacrifices active cooling capability for silent operation. This option is ideal for users who prioritize noise reduction and have a server environment with sufficient airflow to manage passive thermal loads effectively.

Frequently asked questions
Can I use an Intel cooler on AMD Threadripper?
No. All listed alternatives support the SP3 socket, which is specific to AMD Threadripper and EPYC processors. Intel sockets have different pin layouts and mounting hole patterns. You must choose a heatsink explicitly marked for SP3 compatibility to ensure proper physical fit and electrical safety.
What is the difference between active and passive cooling?
Active cooling uses a fan to move air across the heatsink fins, providing stronger thermal performance for higher TDP CPUs. Passive cooling relies on natural convection or case airflow without a dedicated fan. The Dynatron A25 and MITXPC A34 are passive, while the Inter-Tech A41 and Dynatron A39 include fans.
Is copper better than aluminum for server heatsinks?
Copper conducts heat more efficiently than aluminum, allowing for denser heat dissipation in a smaller footprint. The Inter-Tech A41 and Dynatron A28 use copper for superior thermal transfer. Aluminum options like the Dynatron A39 and A26 are lighter and often more budget-friendly, though they may require larger surface areas.
Do these coolers work with 3U server chassis?
Only the Dynatron A50 is designed for 3U chassis. It measures 4.33 inches in height, fitting the taller 3U rack space. Most other options, like the Inter-Tech A41, are built for 1U or 2U servers with lower vertical clearance. Check your chassis height before selecting a model.
How tall is the Inter-Tech A41 compared to others?
The Inter-Tech A41 is 1.12 inches tall, making it one of the lowest-profile active coolers listed. The Dynatron A28 is similar at 1 inch. Taller options include the Dynatron A39 at 4.3 inches and the Dynatron A26 at 6 inches. Height determines which server rack size you can use.
Can I use these heatsinks for desktop gaming PCs?
No. These units are designed for server environments with specific SP3 socket mounts and form factors. The Dynatron A34 verdict notes it is not suitable for standard desktop builds. Server chassis provide the necessary airflow and mounting points. Desktop motherboards use different socket types like LGA1700 or AM5.
What TDP can the Dynatron A39 handle?
The Dynatron A39 supports up to 280W TDP. This is higher than the Inter-Tech A41, which is rated for 225W. The A39 uses aluminum and includes pre-applied thermal grease. It is a practical choice for high-performance Threadripper builds that need reliable cooling within a compact 1U form factor.
