The Sentry 2 is one of the coolest fan controllers I've used, and for one main reason: it's got a touch screen! The Sentry 2 is a nice little treat to add to your system. Along with looking really cool, you'll be able to silence those noisy fans when they don't need to run at 100%. Or maybe you want them to run just enough to keep your system at the temperatures you want. Either way, the Sentry 2 gives you the ability to do this. Along with the ability to control fans, you'll be able to monitor temperatures of up to five different pieces of your hardware. I'll admit it can be hard to find five things you want to monitor, but for those of you with Tri-SLI configurations, the Sentry 2 would be perfect. If you'll use the Sentry 2's temperature sensors as they're supposed to be used, you can set it up so the fans automatically speed up when the areas around them get too hot. If you manually adjust your fans, the Sentry 2 makes for a great way to monitor temperatures on the fly. This means that you don't have to constantly open Core Temp, CCC, HWMonitor, eVGA Precision, or whatever you might be monitoring temperatures with.
