Dynatron A26 low-profile heatsink for AMD's large-format sockets. Full-coverage base for the Threadripper and EPYC heat spreader, heat pipes into a dense fin stack, in a package that clears a 2U chassis. Priced accordingly without the fan.
Two ways to run it
Add your own 60 x 60 x 25mm 4-pin PWM fan. It's a standard size, so you can pick a quieter one than the stock server screamer.
Run it passive in a chassis with strong front-to-back airflow across the fins.
Why this one
Low profile. Fits 2U rackmount and cases where a tower cooler won't clear.
Contact plate sized for the SP3/TR4 heat spreader, not an adapted desktop cooler.
Direct screw-down mounting to the socket frame. No backplate, no brackets.
Compatibility
AMD SP3 (EPYC 7001 / 7002 / 7003)
AMD TR4 (Threadripper 1000 / 2000)
AMD sTRX4 (Threadripper 3000)
AMD sWRX8 (Threadripper PRO, WRX80)
What's included
Dynatron A26 heatsink with 4 captive spring screws
No fan. No thermal paste.
Read before you buy
This heatsink will not cool a Threadripper or EPYC without airflow. Do not run it bare in a still case.
Airflow through the fins is directional. Check your socket orientation.
