Cooler Master's next generation of all-in-one liquid CPU coolers is here. The company's MasterLiquid Pro 120 and MasterLiquid Pro 240 coolers incorporate a number of design changes over the Nepton 120XL and Nepton 240M that could potentially improve their performance and durability. As their names imply, the MasterLiquid Pro 120 uses a 120-mm, 1.5"-thick (or 38-mm-thick) radiator, while the Pro 240 is built with a 240-mm, 1"-thick (or 27-mm-thick) radiator.
At the pump end of the system, Cooler Master says the MasterLiquid Pros' new dual-chamber design offers some advantages compared to single-chamber pumps. The company claims that moving the critical components of the pump into a separate upper chamber lengthens the life of the system by only exposing them to cool liquid. The pump is also built with what Cooler Master calls a new "silent driver" for quiet operation.
The pump moves coolant from its upper chamber into a lower chamber, where it's "sprayed" on the center of the water block. Cooler Master claims this design offers superior performance compared to water blocks where coolant is pumped in at one end of the cold plate before passing over the entire water block. That design is purportedly susceptible to reductions in flow rate as the coolant moves across the dense fin array on top of the plate. The company says that its "spray-down" design also lets it pack more fins on top of the cold plate to increase the fin surface area and potentially improve performance.
The radiator on the MasterLiquid Pros looks unusual, too. Instead of the triangle-shaped fins we usually see on liquid-cooler radiators, the MasterLiquid Pro radiator uses a rectangular fin design. Cooler Master claims that this fin design increases the fin surface area in contact with the radiator channels for better heat transfer and lowers resistance for better airflow. The MasterLiquid Pros both come with Cooler Master's new MasterFan Pro Air Balance 120-mm fans. The company says these high-static-pressure fans use "silent-driver" tech similar to that of the motor in the pump to operate quietly while moving plenty of air.
The MasterLiquid Pro 120 and Pro 240 should be available soon from Amazon, Newegg, Micro Center, and Cooler Master's online store. The Pro 120 carries a $99.99 price tag, while the Pro 240 will sell for $119.99. Stay tuned for our review of these coolers.
