NZXY Sentry 2 is a good fan controller. Its strong points are the presence of five temperature sensors and the capacity of controlling five fans, in manual or automatic modes. The high temperature and stopped fan alarms are also very useful.

It has no USB, e-SATA or audio ports, but these are pratically an exclusivity of two-bay fan controllers, which turns out to be another Sentry 2 advantage over competitors: it needs only one 5 ¼" bay.

It does not show all the temperatures on the screen at the same time like Aerocool Touch-2000, being the best advantage of this particular competitor.

Its installation is very simple, keeping in mind the PWM fans incompatibility issue. But its bigger problem is really the pathetic documentation that comes with this product. We just wonder why the manufacturer didn't included a good manual. Just lazyness?

Sentry 2, however, is a very useful piece of harware, doing fine the job it was designed to. And better of all, it is very inexpensive, providing a terrific cost/benefit ratio.
