The Noctua NH-U12A chromax.black performs well as an air cooler with Alder Lake, able to handle up to 220w long term loads when paired with Intel's i9-12900k - performing almost as well as the bigger NH-D15. The all-black asthetic of this cooler will appeal to those who are tired of seeing RGB plastered everywhere, and Noctua's top-notch customer support means you'll know this cooler will be supported for years to come.
In multi-threaded tasks the 12700 is just shy (~8%) of AMD's Ryzen 5900x on average, and a bit faster (~16%) in single threaded tasks.
