Description

Introducing the Nepton 280L, the latest All-in-One CPU water cooling system that aims to bring heat dissipation to the next level with a CM exclusive designed pump and highly effective waterblock. The Nepton also includes robust and extra thick FEB tubing to prevent moisture absorption while maintaining sufficient water flow for performance cooling. In addition, dual JetFlo 140 fans and a large 280mm radiator provide substantial cooling power, which enables users to overclock their CPU and maximize performance.
High Performance Radiator

The Nepton’s 280mm radiator covers a larger surface area and provides even more water volume for improved dissipation. The radiator also includes compatibility for 140mm or 120mm fans to create a push-pull system.
CM Designed Pump

The CM designed pump and waterblock ensures the best water flow and system performance.
Robust & Extra Thick FEP Tubing

Robust & extra thick FEP tubing is strong and durable for deployment in a 280mm radiator installation. FEP tubing also prevents moisture absorption.
     New UltraFine Microchannel

Designed for the best water flow and to draw maximum amount of heat away from the cold plate through the coolant.
JetFlo Fan Compatibility

The Nepton 140XL is equipped with dual JetFlo 140mm fans which create powerful airflow and pressure while minimizing vibration and noise through the included rubber pads. In addition, the radiator is also backwards compatible with all 120mm fans for total customization.
Illuminated Waterblock

Unique white LED lights up on the waterblock lens.

      "The Nepton 280L is a great mix of fan choice, flow, efficiency, and aesthetics.  As long as a bit of fan noise doesn't bother the extreme clocker's out there, the pricing on this is just too good to pass up on.  Cooler Master has knocked it out of the park with this one."

      "The pump is quiet, and the fans are not terribly loud. I like the JetFlo 140 fans and the fact that they are 4-pin PWM fans. And while we are talking about fans, the JetFlo 120 fans are right at home with the Nepton, and prove that they can move the air when it counts. The rubber pads on the fans help keep any vibrations to a minimum. The splitter power cable for the fans also makes it nice to control both fans from one fan header, and it provides for a clean cable routing since you can run the fan cables and the splitter behind the motherboard tray and keep them out of sight.

      And while the Nepton is well-suited for any case that can handle a 280mm radiator, I was particularly pleased with how well the Nepton 280L and the COSMOS SE case work together. It is as though they were made for each other. Well, I suppose there is probalby some truth to that. 

      The Nepton is really a great addition to the Cooler Master family of CPU coolers."

      "If you’re looking for a liquid cooler to fill your twin 140mm fan mounts, the Nepton 280L is as good of a choice as any.  I wouldn’t have a problem recommending this unit to my friends (especially for the easy installation!)"
