Over on the AMD blog a new entry was posted. AMD Threadripper is close to release and while an Asetek bracket is included with the processors (and thus support like 50% of the liquid coolers LCS kits out there), AMD sheds some light on which coolers are compatible.
Preorders for the AMD Ryzen Threadripper processors went live yesterday, and those with a CPU on the way may be wondering what cooler to buy for the 4094-pin sTR4 socket on the AMD X399 motherboards. Well, my friends, wonder no longer!
First thing's first: included with every AMD Ryzen Threadripper is a mounting bracket that enables compatibility with the following 18 closed-loop cooling (CLC) units as of August 1, 2017. Just remove the bracket(s) included with your CLC, then install the one provided by AMD, and your cooler will be Threadripper-ready:
As of August 1, 2017, there are also another 9 Threadripper-ready coolers on the way that do not use the AMD-provided mounting bracket. Please confirm with the manufacturer or retailer before purchase, as some of these models pre-date Threadripper and are being updated in production to include the sTR4 hardware:
