Peculiar, theres barely a comment on this site of the larger AK620 cooler mentioned in the article yet its about a year old. Review of the AK620 here: https://www.techpowerup.com/review/deepcool-ak620-dual-tower-cpu-cooler/ Seems to hold up a lot better on AMD CPUs, not a bad performer being up to only 6C hotter (load) than the 280mm Liquid Freezer water cooler. Sadly with Intel is up to 10 or 11C hotter.
