MasterLiquid Pro 240 Overview
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.
Most AIO liquid coolers utilize a radiator construction with fins that fold into dense triangles, where only the tips touch the water channel to transfer thermal energy. 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 MasterLiquid Pro 240 AIO liquid cooling solution is said to have been strictly tested and certified by Cooler Master’s professional lab to operate without maintenance for over 160,000 hours. In addition, the entire MasterLiquid Pro series carries a 5-year product warranty.
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 using a dual-chamber block. Liquid heated by the CPU is isolated and immediately drawn away, while cool liquid flows past the pump.
The pump is designed to connect to the (CPU) fan header on a motherboard, and draws a mere 6 Watts of power. The other liquid cooling kits we tested in this article require a fan header as well as a connection to an internal USB port for additional power.
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 next section, we explain the preparation needed for optimal thermal transfer performance. It’s long, but worth understanding the techniques we use to achieve the best cooling results.
