Who each one is for
Take the ARCTIC Liquid Freezer III 420 for buyers who want the largest available Liquid Freezer III radiator without paying Pro-tier ARGB pricing. The same goes for extreme overclocking or high-TDP workstation builds needing roughly 320W of headroom. Avoid it for cases that can't fit a 420mm radiator, which needs a genuinely large chassis. The Corsair H150i Elite Capellix is the one to take for RGB builds already using Corsair iCUE peripherals and 360mm-radiator cases needing flagship-adjacent cooling, though it is not the pick for buyers wanting an LCD pump display and Non-Corsair RGB ecosystems (Link/CAM users). Our rating of the ARCTIC Liquid Freezer III 420 (9/10): one of the best value-per-degree AIOs available at any radiator size, now in its largest non-Pro form. Our rating of the Corsair H150i Elite Capellix (8.2/10): A proven, well-rounded 360mm RGB AIO for Corsair-ecosystem builds without LCD-tier pricing.
