Noctua makes some of the best air CPU coolers out there. When it comes to Ryzen they were one of the only manufacturers to have a full line of AM4 coolers ready. We?ve already taken a look at the big boy NH-D15 SE-AM4, with its amazing cooling performance. While the NH-D15 SE-AM4 is one of the best coolers for Ryzen it can be overkill for many people, and its shear size might not make it for everyone. Well Noctua has a smaller cooler made for Ryzen in their NH-U12S SE-AM4, which of course is their very popular NH-U12S with an AM4 mounting bracket. This single tower cooler features 5 large heatpipes and a 120 mm cooling fan. On top of that it has 100% RAM compatibility, so you shouldn't run into any clearance issues.
