What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Arctic Liquid Freezer III 360
Only Tom's Hardware gave hands-on prose for this exact non-Pro model — two articles by the same reviewer. The verdict: quiet and a good value for gaming and GPU-heavy loads, but it fails maximum-strength CPU-only stress tests (minor thermal throttling), only matching good air coolers, and forces a warranty-voiding LGA1700 contact frame with limited socket support. (2 sourced reviews, 2 lab-tested.)
Praised: Low noise levels for an AIO — among the quietest in the charts; Good value for gaming and GPU-intensive workloads (gaming-load re-test); Low introductory price.
Flagged: Fails maximum-strength CPU-only stress tests; minor thermal throttling; Mediocre noise-normalized performance — only comparable to good air coolers; Forced use of a warranty-voiding LGA1700 contact frame.
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.
