Cooler Master has announced their revised Nepton self-contained liquid CPU cooler lineup, and the existing models have been renewed with lower-noise designs.

The Nepton 240M

The revised versions seem to be using the the same radiators but employ new improvements in the pump/waterblock, as well as new low-noise fans. Cooler Master says the “Advanced Silent Driver” in the Nepton pumps will offer extremely low vibration levels, providing a120 L/hr flow rate at 11dBA. The units feature a Cooler Master-designed water block with a “large microchannel surface area and a high-efficiency jet impingement system to optimize hotspot cooling performance”.

New waterblock and fan designs

Cooler Master says their manufacturing process “eliminates microchannel imperfections in the waterblock to prevent blockage and allows for an increased surface area over 4 times greater than the competition, resulting in an extremely high performance waterblock.” The Nepton series also uses all-new “Silencio” fans, which Cooler Master claims will offer 11dBA noise levels and air pressure rated at 1.2 mmH2O. The cooling performance of previous Cooler Master self-contained liquid coolers has been dependent on some pretty loud fans, and while the stated 11dbA fan noise is likely based on the lowest PWM fan speed improvements in this area are welcome.

The Nepton 120XL

Cooler Master has not announced pricing or availability of the new Nepton 120XL, 140XL, 240M, or 280L models yet, but we should expect these products later this year.
