AMD has published a list of coolers that are officially compatible with their upcoming Threadripper CPUs. It's no surprise there needs to be a compatibility list - the new CPUs top out at 16-core, 32-thread monsters which have never before graced the HEDT space, with an accompanying large CPU die size and heatsink. The socket being an entirely new affair, a new retention kit must also be made available by cooler manufacturers.

AMD itself will be offering an Asetek retention kit for AIO cooling solutions on their Threadripper retail packaging, which should make most Asetek-built AIOs to be compatible with the TR4 socket. These coolers are automatically added to the list. However, there may be some other coolers that are compatible with the newest socket that are not listed on AMD's site as of yet. For those cases, AMD reminds us all that we should check with our cooling solution manufacturer whether an adapter is available or not, and whether our current cooling solution is sufficient for the task at hand. Other coolers are now receiving mid-production updates after a certain date to include the compatible mounting hardware. Check the source link for the AMD compatibility page, and the below image for the current state of affairs.
