Specifications, Availability and Pricing




The chart above addresses the Nepton 280L as the RL-N28L-20PK-1, and shows it will fit on all of the sockets that chips still sell for, and a couple that have long since been noted as EOL. The newly designed head unit, with a new cold plate design to raise the efficiency of the amount of heat the coolant can remove, is only three inches wide with the pair of fittings included. It is slightly less deep without them at 2.7 inches, and from cold plate to the top of the head unit, it stands only 1.9 inches tall. This head unit offers some nice features as well. Not only does it only consume 2.9W at 12V, but it is near silent at 25 dBA, can last up to 70,000 hours, has an LED ring on the top that is lit when powered, and runs at an amazing 7200 RPM. Connected to the swivel fittings on the right side of the head unit, Cooler Master uses three-eighths inch ID, FEP tubing, which increases flow and removes the water permeability factor.


The tubing is also covered in corrugated plastic to protect it from damage, as well as offer anti-kink functionality. At the end of these tubes, they are connected to an aluminum 280mm radiator that is in actuality 300mm long, 140mm wide, and is 30mm thin. The bonus feature here is that increased surface area leads to even more efficiency, and on top of that, there are 140mm and 120mm fan mounting holes in both sides of the radiator so customers have more choices of cooling levels with the fans they select to replace the stock ones.


Speaking of the fans, it is highly doubtful that you will want to replace the pair of 140mm JetFlo fans that are based on a new fourth generation POM bearing. These fans take power via a 4-pin PWM connector, and once fully powered, they are more than capable of taming the thermal testing. These fans are capable of speeds of 2000 RPMs, and at this speed they can deliver 122.5 CFM of air flow and 3.5 mmH2O of static pressure. Looking at the sound rating of 39 dBA: I have a feeling that these fans, while producing some big stats, are also going to be delivering a lot of noise when allowed to run at full speed.


Cooler Master also includes a second set of JetFlo fans, but these are the blue LED lit 120mm versions. These are also based on the new POM bearing, but the specs are somewhat lower. While these also spin at a similar RPM, rated near 2000, they deliver 95 CFM of airflow, 2.62 mmH2O of static pressure, and are rated at 36 dBA in the noise department. We will be testing both sets of fans, by themselves, on the Nepton 280L and will have these results in the charts.


This design is almost to the level of what we saw with the H220, but still being sealed and offering users that warm and fussy feeling they get from using an AIO over something more custom or customizable. Also, most of the dual radiator AIOs on the market release with a $119.99 price point, and all others are just the usual suspect as far as components and designs go. This fact makes the pricing of this much improved design seem that much better.


The previous pricing is for 240mm solutions and not 280mm solutions, and from what we were told, the MSRP of these new Nepton 280L coolers is only $119.99 US dollars. By the time we are done with this review, it will be very easy to see that not only is this a better solution than others are currently offering, but more like stealing it at this sort of a price point.
