Feel the Flow
MasterLiquid Pro 240

Based on our expertise in thermal technology, we reengineered how liquid absorbs and expels heat throughout the all-in-one (AIO) closed loop of the cooler. Our holistic approach to the flow puts in your hands a comprehensive cooling machine that lasts longer, performs better and requires virtually no maintenance.

We call it FlowOp.

FlowOp Technology
Based on our expertise in thermal technology, FlowOp looks at the flow of heat as it is carried and dissipated by an all-in-one (AIO) liquid cooler. Starting with the hot CPU, we reengineered how liquid absorbs and expels that heat. Our holistic approach to the flow of heat puts in your hands a comprehensive cooling machine that lasts longer, performs better and requires virtually no maintenance.
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.
Patented dual-chamber technology

"Spraying" the CPU
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, solving the issue of slow flow. It also allows us to mount even more ultra-fine fins on the copper base, creating even more surfaces 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.
