HD120
There are 2 fan cables that come out each fan. The first is the fan power cable for the fan motor which runs the fan, this is 14″ long and ends in a standard 3-pin black fan header that can be connected directly onto your motherboard. The second is the LED cable that plugs into the fan LED hub, and this is also 14″ long.
There is a hook at the end to be able to lock it in place and also help remove it by pressing down on the hook. The fan cables are flat ribbon style and are unsleeved. So in a triple pack of HD120 you are going to get a lot of wires to contend with.
