Cooler Master’s latest watercooling kit that aims to bring watercooling to the next level. Nepton 280L is using a CM exclusive designed pump with a highly effective water block. It has thicker and longer tubing for upgraded performance. In addition, dual JetFlo 140 fans + an extra large 280mm radiator provide substantial cooling power with over 300W heat dissipation, which enables users to overclock their CPU and maximize performance.

Oversized rad with 140mm fans will limit case options with this all in one. But if you can fit it, go for it. Build quality is top class, good decent length and quality tubing and a stunning CPU block that lights up the outer ring of the logo. Fans supplied are of a high quality with very little noise and good air flow. *NOTE* As we are yet to test the cooling, it's difficult to compare this to other coolers, but once this has been done we will update.


Would be nice for the entire logo to light up.
