The Cooler Master Nepton 240M is a high-end liquid cooling system for CPUs. It has a 240 mm radiator with two 120 mm fans. Let’s see how it performs.

As with any sealed liquid cooling system, the Nepton 240M comes with the coolant liquid pre-filled inside the loop (block, radiator, pump, and hoses).
