Features:
The FC4 is a stylish brushed-aluminum fan controller with brushed aluminum dials, four in total. To satisfy most tastes you can also get it in black or silver. Regardless of your colour choice, the four dials will all have blue LED backlighting surrounding them (pictured later).

When you spin it around to the back you'll see that it takes the standard 3-pin fan connector on each channel. Lamptron includes four 3-pin extensions to help with difficult wire routing when the fan cables won't reach on it's own. I was happy to see a standard 4-pin molex power adapter so I can plug my power supply directly into it and not have to worry about a separate power cable hanging off the back (on windowed cases, less is best!).

Each channel of the FC4 can control up to 20 watts, I usually find wattage ratings like this on higher end controllers I see. If you cheap out on a fan controller, you're likely to get 7-12 watts per channel (avg.).
