Cooler Master has just announced their new MasterLiquid series of CPU coolers, built using a special “FlowOp” technology that analyzes how heat is absorbed and dissipated to construct a better cooling solution than the competition. The end result was a dual chamber design that did both improve the cooling performance, but also dramatically extended the product’s functional lifetime. In this preview article, Benchmark Reviews covers some of the finer points that separate the MasterLiquid cooler series from everything else on the market.

To use the new MasterLiquid series of CPU coolers, you’ll need a computer case with either a 120mm (for Pro 120 – $99) or 240mm (for Pro 240) fan opening to mount the radiator. Cooler Master includes a myriad of brackets for mounting the waterblock to any CPU socket seen in the past ten years (or more).

MasterLiquid Pro 240 Specifications


Based on outward appearances, MasterLiquid Pro 240 (as well as Pro 120) appears very similar to every other liquid cooler you’ve seen lately. There are several critically important differences within, but on the outside two primary differences are making a big impact: MasterLiquid’s unique square fin radiator design, and MasterFan Pro Air Balance fans.

Cooler Master took a fresh approach to solving this problem by uses square fins with larger contact surface and more spacious fins that make it easier to push air past.

MasterFan Pro Air Balance fans have a life expectancy of 160,000 hours MTBF (mean time between failure), which rates 10K more than Noctua, and 100K longer than Corsair. In addition to the extended lifespan of these components, the fans are also rated to produce a mere 6-30 dBA of noise –  practically inaudible.

The waterblock on MasterLiquid Pro bears a striking resemblance to high-end custom waterblock components, which is not by mistake. Cooler Master isolates the heat-sensitive pump components by uses a dual-chamber block. Liquid heated by the CPU is isolated and immediately drawn away, while cool liquid flows past the pump.

Every single computer case Cooler Master has made in the past decade will accommodate the MasterLiquid Pro 120, while all but three models (Scout II, Elite 110/130) will have the dual 120mm opening required for MasterLiquid Pro 240. For best results, mount the radiator so that fans blow air directly upward and out of the enclosure.

In the coming weeks, Benchmark Reviews will compare performance of the MasterLiquid Pro series against other AIO cooling solutions. As the weather warms up outside, expect your computer to need assistance keeping cool.

    It certainly looks impressive for an A.I.O.
    I can’t wait to see a comparison.

    been a few months, you guys working on a review for this?

    1. Olin Coles

      As it turned out, the sample Cooler Master originally sent was pre-production and had some fitment issues with the mounting bracket. Although we requested a replacement along with others from their product line, they were not sent. Sorry to keep you waiting, and we’re sorry it didn’t come to fruition.
