Summary: Easy to use. Looks good. Led panel is bright. Touchscreenis responsive. All fans works perfectly. Was very easy to install and set up. Nzxt makes amazing products! Only cons. The beeping sound can get annoying but you can just turn it off.
Nice fan controller with a couple things to nitpick
18 December 2014
Summary: The Sentry 2 is pretty dang nice, I'm not gonna lie. The screen is bright and has a pretty decent viewing angle (I can see what I'm doing without having to leave my chair) and having an auto setting that adjusts fan speeds based on the temp reading from the sensors is really nice too.
Summary: Great product for the price. You can easily switch between manual and automatic mode. This allows me to enable and disable a blue fan that I have installed. You can also hook up your CPU fan to this product to keep it under control, but use caution when doing so.

Summary: The only thing separating me from giving a 5 star rating for this fan controller is that the power inlet socket had a loose cable. I had to check everything twice or three times until I finally detected the issue. The power inlet socket was built with bad quality!
Summary: i bought this because my motherboard couldn't support more than four fans and I have six. It does what its suppose to do.The temp sensors are great like how they can go any where in my case so i can monitor key components. manual doesnt have details but i figured it out in two minutes.
Summary: The fan controller can turn off the fans manually if you want to turn off any, the only thing that would perfect is to be able to turn off the screen, it can only be turned off if you turn off your pc, everything works fine as it is described on amazon and on the box, must own, buy it
