A New Way
to Flow
MasterLiquid 240
Innovation - It's Our Thing
Cooler Master controls quality and builds on decades of innovation with 100% in-house design and manufacturing.
Low-Profile Dual Chamber
Its fiber-reinforced polymer (FRP) construction resists a broad range of chemicals and is unaffected by moisture or immersion in water. Our pump is light and impervious to oxidation and corrosion.
Liquid and Air
One of the greatest advantages of liquid cooling is silence. The sturdy build of MasterLiquid coolers mean less noise and vibration, making our AIOs some of the quietest in-class.

Getting the
Heat Outside
The MasterFan Air Balance 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.
Easy Installation
Many of Cooler Master's products are known for their easy installation.
To fit our MasterLiquid lineup to the motherboard and install fans,
all you need to bring are your two hands and a screwdriver.
