Both the X- and Z-series coolers also come with the new Asetek pump, which is supposedly more powerful and quieter. In addition, you'll find a dedicated NZXT RGB connector on the pump itself, which may come in handy for hooking up extra NZXT RGB accessories, such as its cable combs or lighting strips.

The coolers are equipped with either Aer P120 or P140 fans as well. These are high static pressure fans designed for use on radiators, and it's a pity NZXT hasn't taken this opportunity to introduce RGB versions of its radiator fans. The Aer RGB 2 fans are some of the best-looking RGB fans around, but they're better suited for use as case fans.
