## What reviewers say

**Deepcool LS720** — Only one whitelisted tester — TechPowerUp — published a genuine hands-on lab review of the exact LS720 360mm AIO (Sept 2022). It calls the cooler good for AMD with fantastic build quality and best-in-class mounting hardware, but heavily outperformed on Intel, and can only recommend it for AMD systems. All quotes and pro/con points verified verbatim against the review's Value & Conclusion page. (1 sourced review.)

**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.)
