Maximum PC: Cooler Master's been hard at work updating its liquid cooling line, and what the company came up with is the Nepton 120XL and Nepton 240M. These are the newest additions to the Nepton family of closed-loop water coolers, and what they bring to the table are new fan designs. They use Silencio FP 120 fans to deliver high-pressure performance at lower noise levels than their predecessors.
