Arctic Liquid Freezer III 240 vs Thermalright Peerless Assassin 120 SE
The Peerless Assassin 120 SE is the safer buy for most people: it cools 245W-class CPUs, has no pump to fail, and costs far less than any AIO. The Liquid Freezer III 240 wins on sustained heavy loads, fits tighter cases, and keeps weight off the motherboard, but adds pump noise and a wear part. Reviewers rate both as class leaders; the Arctic edges out on thermals, the Thermalright on value and simplicity.
- Choose the Arctic Liquid Freezer III 240 if you run a high-wattage CPU under long all-core loads and want the lowest sustained temperatures with a compact 240mm radiator.
- Choose the Thermalright Peerless Assassin 120 SE if you want strong cooling with no pump, no software and nothing to wear out, and your case fits a 157mm-tall tower.
