## What reviewers say

**Thermalright Peerless Assassin 120 SE** — Only one whitelisted tester, Tom's Hardware, ran a hands-on lab review of this exact model. That single review is overwhelmingly positive: the best-performing air cooler it had tested, whisper-quiet, at roughly $36. It averaged 61 degrees C over ambient in a 200W Cinebench load and 64 degrees C over ambient in a 200W OCCT load, beating pricier coolers. No meaningful downsides beyond air-cooling's inherent power ceiling. (1 sourced review.)
