Cooler Master Nepton 280L AIO Liquid CPU Cooler Review

Cooler Master Nepton 280L Overview
Removing the components from the bags you will find a pretty standard selection of parts. Of course there is the unit itself, two JetFlo 140mm fans, a bag of installation accessories, a warranty card, and an installation guide.

The JetFlo fans claim a max dBA of 39 at 2000rpm while pushing 122.5 CFM and creating 3.5mm of pressure. By the specs, these should be excellent for the thin 280mm radiator in this kit. The rubber dampening pieces on the corners should be very helpful at reducing any noises caused by vibration.

One of the most important parts of a watercooling loop is the pump. If it is too weak it won’t be able to circulate water efficiently enough to cool the CPU. It is also the most likely part to fail. Thankfully CM has included a pump in this kit that is a proprietary design to CM. This pump while taller than many others we’ve seen lately, is built to a high standard and should last 70,000 hours of use. We have very high expectations for this pumps functionality. The base of the pump is an all copper cold plate with ultra thin micro channeling for maximum heat transfer to the factory filled coolant. And finally powered by a single 4 pin plug the pump top has a built in LED.

Attached to the pump we find some pretty thick FEP tubing that is extremely durable and should be plenty long enough to allow for an easy installation of the 280mm radiator.

The radiator itself as mentioned is quite thin. It’s actually one of the thinnest radiators we’ve seen used in an AIO kit. Fortunately though we find that it has a pretty high fin count which will help to make up for it’s lackluster width. Additionally the high speed JetFlo fans will help as well.

And finally of course we have the bag of installation accessories. You will find all the parts needed for installation in most all Intel and AMD socket types. Also included is a fan splitter and a tube of CM brand thermal paste good for 3-4 installs depending on the amount and method used.
