What is the best CPU cooler? The key to a good CPU cooler, for most people, is that it should not only keep your CPU cool but remain quiet while doing so. Some users may prefer all-out cooling performance over noise suppression or need a super low-profile cooler to fit in a tiny PC, though. Whatever your needs, we’ve got a CPU cooler for you. The best CPU cooler overall is the Thermalright Peerless Assassin, as it provides the ideal balance of cooling capacity, noise, and price to suit most gaming PC builds. For an even more affordable option, the Cooler Master Hyper 212 Halo White is your best bet, while the NZXT Kraken 240mm is our top AIO liquid cooler pick.
