ARCTIC Liquid Freezer III 420 vs Enermax LIQTECH TR4: which one fits your build
Take the ARCTIC Liquid Freezer III 420 for buyers who want the largest available Liquid Freezer III radiator without paying Pro-tier ARGB pricing. It also earns its place with extreme overclocking or high-TDP workstation builds needing roughly 320W of headroom. It is not the one for cases that can't fit a 420mm radiator, which needs a genuinely large chassis. The Enermax LIQTECH TR4 is the one to take for AMD Threadripper sTRX4/TR4 workstations and high-core-count HEDT builds, though it is not built for mainstream AM4/AM5/LGA1700 builds and budget-focused workstations. 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 Enermax LIQTECH TR4 (8/10): the correct choice for Threadripper, full IHS coverage that generic AM5/LGA1700 coolers can't match.
