AMD Ryzen™ Threadripper™ processors with 180W TDP require the type of robust cooling solutions provided by premium liquid cooling. The following list contains some of the thermal solutions submitted by manufacturers with specifications to support the 180W Ryzen Threadripper Processors. Right now, there are around 20 different coolers with confirmed support, including models from Corsair, Fractal Design, Cooler Master and more. If you really want good performance, wait until there are custom made cooling solutions for threadripper. Asetek (AIO), EKWB and Alphacool (custom water) and Noctua (air) are all developing solutions that cover the WHOLE DIE right now.
Still, if you are planning a Ryzen Threadripper build and want to ensure you pick up a compatible cooler, AMD will be updating its list over time, so it may be worth bookmarking and checking when you are ready to buy.
