ARCTIC Liquid Freezer III 420 vs Thermalright Silver Soul 135: 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 is equally the pick for extreme overclocking or high-TDP workstation builds needing roughly 320W of headroom. It is the wrong buy for cases that can't fit a 420mm radiator, which needs a genuinely large chassis. Buy the Thermalright Silver Soul 135 for enthusiasts wanting flagship-adjacent cooling on a budget and single-fan-clearance cases, though it is not built for buyers wanting premium brand warranty support and RGB-themed builds. 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 Thermalright Silver Soul 135 (8.1/10): near-flagship single-tower cooling at a fraction of the premium-brand price.
