The criticism was inspired by a flaw. I bought this cooler without considering the sort of attachment for am4 moms. The mother arching that PPC after only two weeks of use. That might be the last for her. This drawback may be readily remedied, at least for the AM4 socket, if the maker simply used longer bolts, as is done on a regular back. After 2 weeks of use, the mother arch can be seen in the photo (after removal, the void was even more pronounced). If so, this cooler is a fantastic value for the money; otherwise, I would not suggest it to anyone.
