Not all coolers support all CPU sockets. Cooling for AMD Threadripper CPUs can be tricky for example. Also, Intel 12th Gen LGA1700 compatibility is more and more important these days. So, if you’re planning on building an Alder Lake system, pay close attention to the list of supported sockets. Stock from earlier in 2021 will definitely lack support. You can expect manufacturers to offer compatible mounting kits and updated SKU’s but if you’re planning on upgrading to 12th Gen, make sure you check with the retailer or manufacturer to ensure your choice of cooler includes LGA 1700 support now, or if it will in the future.
