The Arctic Liquid Freezer II 420mm CPU cooler is a new best cooler for AMD Ryzen, but the margin is small vs. the 360. More interestingly, the offset mount gets benchmarked vs. standard.

This benchmark of the Arctic Liquid Freezer II 420 liquid cooler tests it vs. the 360, 280, and EK AIO / Galahad coolers. Of course, we also have air coolers for AMD Ryzen CPUs tested, if you'd like to see the benefits of air vs. liquid in a CPU cooling scenario. This cooler uniquely offered an opportunity to test an offset mount versus a "standard" full IHS coverage mount, something that Arctic released after its initial launch of the Liquid Freezer II line. We'll look at both mounts to see which does better.
