Excellent
It's Noctua, it's efficient and very reliable (no risk of pump failure). It's more than enough to cool down a Ryzen 5 5600X which is barely heating up. The top flows are not necessarily the most efficient in absolute terms, but I like the look (if you like brown and beige) and it sends a constant flow of air over the ram and vrm which is not a bad thing. But if you have ram's with led's it will hide them.
