Cooler Master Nepton 140XL AiO Liquid CPU Cooler Review

There is a bit of a “square peg, round hole” situation that exists in liquid cooling. What I am referring to is radiator sizes in relation to fan openings in cases. While there is an abundance of radiators based on 120mm form factor, it has been more prevalent for cases to use 140mm fans in recent years. While 140mm mounts in cases almost always have mounting for 120mm fans/rads, it is obviously not optimal. After all, surface area is one of, if not the largest determining factor in radiator performance and heat dissipation. It would only stand to reason to try to use all that is available.

 Cooler Master Nepton 140XL

While 140mm based rads are becoming more available in custom loops, AiO users have still been left with only one choice of single and dual 140mm, albeit with two brand names and fan choices. There has also been far less in the way of high static and flow 140mm fan choices, with most of the top name rad fans not even offered in 140mm variations. It’s been shown that many of the top end 120mm fans outperform almost any 140mm fan, but that requires adapters for mounting purposes. So, it leaves a bit of a quandary. Ideally, what would make sense is 140mm based AiO with native mounts for 120mm fans that would also allow it to mount in many cases with 120mm fan openings.

 

 Cooler Master Nepton 140XL

 

With the Nepton 140XL, Cooler Master has addressed this and offers the increased thermal performance of a 140mm radiator with included optional 120mm mounts. However, the included dual Jet Flo 140mm fans of the Cooler Master Nepton 140XL do not fall short of 120mm fans as we have seen so many times in the past, and feature 122 CFM airflow with 3.5mm H2O of static pressure. To boost performance further, the thickness 140mm radiator of the Nepton 140XL is extended to 38mm, which is a 50% increase over standard AiO radiators. At the heart of the Nepton 140XL is a Cooler Master designed pump which is incorporated with a solid copper contact plate using ultra-fine micro-channels for increased heat dissipation. FEP tubing is used between the pump and the radiator, with excellent flexibility and durability. On the installation side, the Cooler Master Nepton series are the first AiOs on the market to feature completely tool-free installation, and including hardware is compatible with Intel LGA 775/1150/1155/1156/1366/2011 and AMD AM2/3 and FM1/2.
