Neoseeker posted a review of Corsair's Nautilus 500, a water cooling kit

Watercooling kits of this type are intended to ease users in the transition from air coolers to watercooling with the idea being for users to move towards a much higher performing cooling solution. A common problem with some of these water kits is that they can fail to really achieve either goal at all, sometimes offering worse performance than even good air coolers. The Nautilus, thankfully, isn't one of those offerings. It beats out the G-Power, one of the best air coolers that we use, and it doesn't sacrifice simplicity in its search for high performance.
