Coolermaster's Nepton 280L is the best performing all-in-one CPU watercooler Frostytech has tested... thus far. More surprisingly for us, the Nepton 280L managed to rise to the top of the 200W Intel LGA2011, 150W & 85W Intel LGA115x/775 and 125W AMD synthetic thermal heatsink test results charts. After testing +750 CPU thermal solutions, it's kind of nice to be surprised.
