Cooler Master Nepton 240M – Review

I really want to thank Cooler Master for sending me the huge care package, the last of my reviews is for the Cooler Master Nepton AIO (All in One) cooler.

The Nepton 240M is a custom designed sealed AIO water cooler compatible with almost all sockets, designed for those that don’t want to spend time making a custom loop, but want the additional performance that a water cooler offers. Now that doesn’t mean that a closed loop will offer as good a cooling experience as a custom loop, far from it. It is a trade-off for convenience over bulky air coolers and custom loop cooling.
