Our top pick: Dynatron Threadripper and EPYC CPU Cooler.
Comparing Threadripper SP3 Cooler Options
Dynatron 2U Active Aluminum SP3 Heatsink
The Dynatron A26 is designed specifically for 2U server chassis, whereas the A39 is a general-purpose desktop cooler. This alternative uses an aluminum frame with embedded heatpipes for active cooling on SP3 sockets. It measures 4.5 by 5 by 6 inches and weighs 1 pound. You choose this if your build requires a 2U form factor for a server rack or similar enclosure. It lacks the compact footprint of the A39 but fits standard 2U spatial constraints. The active cooling method ensures heat dissipation in dense server environments where airflow might be restricted compared to a standard desktop case.
MITXPC Threadripper EPYC Passive 2U Heatsink
The MITXPC Dynatron A34 offers passive cooling, meaning it has no fan. This contrasts with the A39, which includes a fan for active heat removal. The A34 is a 2U heatsink made for SP3 sockets, measuring 3.15 by 4.45 by 2.52 inches. You should pick this if your server has strong case airflow and you prioritize absolute silence. It gives up the guaranteed cooling performance of a fan. This option suits users who already have robust system fans or liquid cooling loops handling the thermal load. It is a silent solution for builds where noise is the primary constraint.
Inter-Tech 1U AMD Copper Heatsink
The Inter-Tech A41 is a 1U copper heatsink for SP3 sockets. Unlike the A39 aluminum unit, this uses copper for higher thermal conductivity. It measures 3.23 by 4.72 by 1.12 inches and weighs 1 pound. It includes a fan for active cooling in compact 1U enclosures. You choose this if your chassis is extremely shallow and requires 1U height. It gives up the larger surface area of the A39 for a smaller footprint. The copper material may offer better heat transfer in tight spaces. This is the right choice for dense, low-profile workstation builds where space is more limited than in standard desktop towers.
Dynatron 2U SP3 Heatpipe Cooler
The Dynatron T17 is a larger 2U aluminum heatsink rated for 280W TDP. It measures 6 by 6 by 4 inches and weighs 2 pounds. The A39 is smaller and lighter. This alternative provides more mass for heat dissipation in 2U or taller cases. You pick this if you need maximum cooling capacity for high-TDP SP3 processors in a server environment. It gives up the compact size of the A39. The increased weight and dimensions require a sturdier mounting solution. It is ideal for users who prioritize thermal headroom over space savings in their 2U server chassis.
Dynatron 3U Socket SP3 Heatsink Fan
The Dynatron A50 is a 3U SP3 server heatsink with a fan. It measures 3.23 by 4.69 by 4.33 inches. The A39 is smaller and fits in more varied cases. This cooler is designed for 3U chassis with a 280W TDP rating. You choose this if your build uses a 3U server frame. It provides more vertical height for the heatsink fins compared to the A39. The active cooling ensures performance in larger server enclosures. It is not suitable for standard desktop cases due to its height. This option fits users who need a dedicated solution for 3U server racks.
Dynatron 1U Passive Copper Heatsink
The Dynatron A25 is a passive 1U copper heatsink for SP3 sockets. It has no fan, unlike the active A39. It measures 3 by 4.4 by 1 inches and weighs 1.3 pounds. You pick this for silent 1U server builds with existing airflow. It gives up the fan-assisted cooling of the A39. The copper material aids heat transfer in a very small volume. This is for users who prioritize silence and have a chassis with strong fans. It is not a plug-and-play solution like the A39. It requires careful thermal planning to ensure the passive design handles the processor heat load.

Frequently asked questions
What is the smallest height for a SP3 socket cooler?
The Inter-Tech Dynatron A41 and Dynatron A25 both offer 1U form factors. The A41 copper heatsink measures 1.12 inches in height. The A25 passive copper model is slightly lower at 1 inch. These options fit the tightest server chassis available for AMD Threadripper and EPYC processors.
Which SP3 cooler does not use a fan?
You can choose passive cooling for silent operation with the MITXPC Dynatron A34 or the Dynatron A25. The A34 is a 2U aluminum heatsink. The A25 is a 1U copper heatsink. Both rely on case airflow rather than active fans to dissipate heat from the CPU.
How wide is the Dynatron T17 SP3 heatsink?
The Dynatron T17 measures 6 inches in width. It also spans 6 inches in length and stands 4 inches tall. This larger footprint allows it to handle 280W TDP loads effectively in 2U or taller server cases while maintaining active cooling performance for SP3 sockets.
Is there a copper option for 2U SP3 builds?
The available 2U options listed are made of aluminum. The MITXPC Dynatron A34 and Dynatron T17 both use aluminum construction. If you require copper for 2U, you must look to 1U models like the A25. The data does not list a copper heatsink for the 2U form factor.
What is the weight of the MITXPC A39 cooler?
The MITXPC Dynatron A39 weighs 1.65 pounds. It measures 3.2 inches wide, 4.7 inches long, and 4.3 inches tall. This compact aluminum heatsink includes a fan and is designed for active cooling on sTRX4, TR4, and SP3 platforms with up to 280W TDP.
Which SP3 cooler is rated for 280W TDP?
