## 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.)

**Lian Li Galahad II Trinity Performance 360** — Two whitelisted testers, Tom's Hardware and TechPowerUp, both lab-tested this exact 360mm Galahad II Trinity Performance and crown it a class-leading 360mm AIO on raw cooling at a reasonable $169.99, while flagging very loud full-speed fans (55.2 dBA on Tom's Hardware, 63 dBA on TechPowerUp). Every quote and measured figure below was reconfirmed against the published review text. (2 sourced reviews.)
