Summary: Solid build quality. The levers feel very smooth going up and down, and the mesh front looks nice (and fits fine as well) in the front of my Define R4. Not much to say about this, works perfect and looks good, as well as a fair price.
Summary: Works great fans do not turn off when all the way down but you can't hear them. Bought the four pack of cooler master fans and they work well with it. Some things to note it does not come with any fan splitters so if you have more than 5 you will need to get those.
Summary: I didn't need a fancy fan controller with all the RPM reading and everything. Just a simple controller that will allow me to manually turn them up and down. I had to purchase an adapter for my existing fans, since all my fans were 4 pin molex and this has the smaller 3-pin.
Summary: Installed fairly easy and I've had no issues so far, I'm running 4 or my 7 computer fans off of it. The only gripe I have is if you have a fan with a 4 pin connection you will have to "modify" the connections on this controller, since they are only built for 2/3 pin connectors.
Summary: This thing does exactly what it is designed to do. I opted for this controller because, in my opinion, an analog controller has a far less likelyhood of something going wrong than that of its digital counterparts. Second, the mesh grill blends beautifully with the mesh on my blackhawk case.
Summary: The controller has a loud and annoying buzzing sound when the sliders are any position except the top and the bottom. No problem if you want to run your fans only at 40% or at 100%. Unacceptable.
Summary: I bought the basic NZXT Sentry Mesh Fan Controller (with the sliders). I have 5 case fans and only about 3 fan ports on my mobo. It's got a simple basic look that I like and is easy to use. Installation was quick and painless... other than a little wire management issues due to my case.
