Cooler Master Nepton 140XL Review
Introduction
The Nepton range from Cooler Master joins the Seidon and Eisberg, adding 140mm radiator performance to the series. The Nepton is available in two flavours, the 280L which is a 280mm rad based set up having fans on one side and the 140XL we have for review today. Being based on a 140mm as opposed to a 120mm radiator the Nepton should, we hope, give reasonable results in our torture tests. However being bigger than 120mm rad based systems it may not fit into quite as many cases as its smaller brethren. That said with a good few SFF cases also offering 140mm fan support, in particular the Prodigy chassis based cases from Bitfenix, so aside being compatible with a great many of the Cooler Master range of cases, we don’t think size will be too much of a limiting factor, that is of course provided the arduous torture tests don’t throw us any surprises.
