Just a short few weeks ago, we took a look at a slightly older Cooler Master all-in-one liquid CPU cooler the Nepton 280L. That cooler has been on the market for nearly a year, which gave Cooler Master enough time to come up with a more refined version. We're going to take a look at the smaller sibling called the Nepton 240M. Don't be fooled by the name and the fact that it is smaller, as Cooler Master promises a quieter and similar performing package than what the 280L offered.
