Cooler Master MasterLiquid Pro 140 Liquid CPU Cooler Review

Generally speaking we PC users, hardware enthusiasts, nerds, like to have the highest performing parts we can get our hands on. If I need a new GPU, I sort results by most expensive. Upgrading to HEDT, you bet we want that i9-7900X; at least until that i9-7980XE is available. And when it comes to keeping these parts cool, once again we find ourselves reaching for that custom watercooling loop or at least a big 360 rad AIO. This pattern of excess is basically the hallmark of the hardware enthusiast and there is nothing wrong with it. On the other hand there are the occasional times where maybe all that over the top performance isn’t required or maybe there are certain limits like budget or space holding you back. Today we’re going to check out one of those products, the Cooler Master MasterLiquid Pro 140. While not the big gun feature item of the CM lineup, we are still quite curious to see just how this dual fan equipped 140mm AiO liquid cooler performs.

Special thanks to Cooler Master for providing the MasterLiquid Pro 140 for review!

FlowOp Technology
Starting with the hot CPU, FlowOp looks to optimize the flow of liquid, enabling it to carry heat quickly and efficiently away from the CPU while preserving the lifespan of the components. To achieve this, we made improvements to practically every phase of the MasterLiquid Pro’s cooling loop

A Dual Approach to Life Expectancy
We stacked an extra chamber on top and engineered it so that cold stuff can go in, but hot stuff can’t go back up. The cooler upper chamber is where we store all of the vital components.

“Spraying” the CPU
We stacked an extra chamber on top and engineered it so that cold stuff can go in, but hot stuff can’t go back up. We grabbed technology from top-end DIY liquid cooling kits to create a powerful pump that sprays liquid directly at the center of the water block. It solves the issue of slow flow and allows us to mount more ultra-fine fins on the copper base, creating more surface area from which the coolant can take away heat.

Gently Driven
Adding to that effort towards silence, we encased the pump needed to drive that concentrated spray at our CPU with a silent driver. The custom driver rotates way more smoothly than any other technology out there, reducing noisy clicks and vibration. It’s like you’re using a V8 engine and can’t even notice.

Easy Installation
Many of Cooler Master’s products are known for their easy installation. To fit our Pro lineup to the motherboard and install fans, all you need to bring are your two hands and a screwdriver.

Spacious Squares for Air
The MasterLiquid’s unique square fin design creates greater surface area for absorption of the heat and allows for spacious airflow. The increased space means we can use a quieter fan that pushes air farther out of the case. It’s really quiet.

Getting the Heat Outside
The spacious square fins gave us leverage to use all-new MasterFan Pro Air Balance fans. The blades push air farther out of the case and are quieter than high static pressure fans. And they’ll last just as long as your liquid cooler.

Like the rest MasterLiquid Pro series, the Pro 140 comes in a mostly matte black cardboard box shrinkwrapped in cellophane. It seems that CM went with a standard size box for this series as even this smaller 140mm cooler is in the same size box as it’s larger siblings. Along with the black background you’ll find a photo of the cooler as well as white and blue text on the front.

Flipping to the back of the box we find a whole bunch of information about the cooler as well as technical drawings and data translated into eight languages. In addition there is a pretty cool exploded view of the pump that demonstrates the dual chamber design. One more rotation gets you information in an additional 14 languages as well as contact info. The final long side is simply a plain matte black background with product name and logos in white and blue.

On the right side of the box you will find the complete technical specification list the same as what you will find listed earlier. Finally flipping to the last side of the box you get another photo showing the base of the pump.

Flipping the top back we find the cooler nestled in the same all cardboard container that the other bigger coolers shipped in. We have found this design to be completely sufficient for protecting the cooler during the shipping process as well as very innovative. We’d also venture a guess that this packaging makes the box entirely recyclable and a bit more environmentally friendly. Open the singular separate box we find that it contains all the accessories and hardware.
