What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 1 lab-tested.)
Praised: Best-in-class air cooling performance for its class, beating pricier coolers at capped TDPs; Whisper-quiet acoustics; second-quietest air cooler tested at max fan speed; Exceptional value at roughly $36 for a dual-tower, dual-fan cooler.
Flagged: Cannot keep a 12900K under TjMax in uncapped Cinebench/OCCT without power limits, a ceiling shared by all air coolers tested.
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, 2 lab-tested.)
Praised: Class-leading / best-in-class 360mm cooling performance; Reasonable $169.99 price for the performance delivered; Fast, easy installation with pre-installed fans.
Flagged: Very loud fans at full speed (55.2-63 dBA measured); Plastic AMD AM4/AM5 mounting clips feel less premium; Fan ARGB lighting kit costs extra / ARGB not for everyone.
