What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 1 lab-tested.)
Praised: Excellent, easy-to-use mounting hardware, especially on AMD/AM4; Fantastic build quality; solid, durable fan frames; Attractive price plus 5-year warranty; strong value.
Flagged: Lackluster cooling performance on the Intel test bench; Proprietary fan connectors; Pump cap uses white LEDs (not ARGB); green DeepCool logo mars the ARGB look.
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.
