The Thermalright Peerless Assassin 120 SE has established itself as the go-to recommendation CPU cooler for anyone building a budget gaming PC. Thanks to its combination of great cooling capacity, reasonably quiet operation, and rock bottom price, it's a great choice, even for surprisingly powerful CPUs. Now, it's back for its third iteration, with the new Thermalright Peerless Assassin 120 SE V3 adding slimmer but faster-spinning fans and a tweaked fin design. It's not the most revolutionary update to the best budget CPU cooler, but it should mean Thermalright's stalwart remains a solid choice for years to come.
