Should you buy it?
Buy this cooler if you absolutely need the smallest possible cooler for an AM5/AM4 system with a 65W TDP CPU (like a Ryzen 5 7600) and prioritize silence and compact size above all else. For higher TDP CPUs or less restrictive cases, larger and more performant coolers offer better value and thermal headroom.
