Arctic is a name well-known by many PC enthusiasts for often providing high-value, quality cooling solutions. Arctic’s MX-6 is one of the best thermal pastes on the market, and the Liquid Freezer III Pro 360 showed some of the best liquid cooling results we’ve seen when tested on AMD’s Ryzen 9 9950X3D and Intel’s i7-14700K.
Since the release of the Liquid Freezer III Pro , many loyal readers have been requesting that we test the 420mm version of this powerful cooler. And so we’ve tested it with AMD’s Ryzen 9 9950X .
Not to get ahead of our testing, but this cooler will certainly be a strong contender for a spot on our Best AIO Coolers list. It offers industry-leading cooling performance at a very reasonable price. But before we get to testing, let’s look at the cooler’s specs and what’s included in the box.
