Indeed, a company rep said on Twitter, answering a user's question:
We can't reveal any details yet due to a nondisclosure agreement, but we're working on it and you should definitely be able to continue using your NH-U12A via an upgrade kit!
Noctua NH-U12A is a high-end cooler compatible with a wide variety of sockets, including AMD's AM4, Intel's LGA1200, LGA115x, LGA2011 and LGA2066. Apparently, the device will also be compatible with future Intel CPUs using a new mounting kit.
There is a problem though. According to EXPreview, Intel's upcoming LGA1700 processors may be 0.8mm thinner than their existing counterparts. Bearing in mind that the LGA1700 socket will be completely different from the existing ones and that Alder Lake-S (or perhaps its successor) should be less thick than its predecessors, compatibility with the coolers already on the market will depend on the ability of their manufacturers designing a mounting kit that will take into account not only the size of the CPU, but also its height.
Recall that the 12th generation Intel Core desktop processors, codenamed Alder Lake-S, will introduce various news. First, they will be Intel's first hybrids with high-performance cores accompanied by others that aim for energy efficiency. Second, Alder Lake-S will be the first CPU to support DDR5 memory and the PCIe 5.0 interface. Finally, Alder Lake-S will use the brand new LGA1700 socket.
LGA1700 will be the first major upgrade to Intel desktop CPU sockets since 2004. At the time, the company introduced its LGA775 socket which measured 37.5 × 37.5mm, later replaced by LGA1155, LGA1156 , LGA1150, LGA1151 and LGA1200, which have kept the same dimensions, although obviously they have changed the number of pins and their layout. LGA1700 will keep the width of 37.5mm, but increase its length to 45mm, which may require cooling systems with a larger base and a different mounting mechanism. As LGA1700 socketed processors will not only be physically larger than those marketed by Intel for the past 17 years, but also thinner, heatsink manufacturers will have to work further to ensure proper compatibility and performance. a Windows 10 Pro license for your brand new gaming PC?
