For boosting performance, consider AIO solutions.
You're considering whether an AIO is necessary for boosting your i5-10600K to higher speeds. For reaching at least 5GHz, a cooler like Cooler Master MasterLiquid ML360R is a solid choice. You can likely get away with a 240mm radiator if you're not pushing extreme temperatures, but a 360mm would provide better airflow for sustained overclocking. If you want the best performance and reliability, go with the 360 radiator.
280s tend to offer the best balance of sound and silence, though some enthusiasts prefer the EVGA CLCs despite their louder fans—just stick with them if you value quiet operation. 360s match around that level, possibly a tad better with three fans versus two. 240s are a bit less ideal, but still decent for a 10600K. Just pick a model with your preferred features and look for a solid warranty, ideally at least three years, though five years is becoming more common now.
I generally suggest AIOs only when you have limited space. Otherwise, add an air cooler. A d15 should work just as well and last longer.
These options fit well together, covering a range of sizes and brands.
