fans should be connected to the 3 or 4 pin plug on your motherboard (might be labeled as "fan." or a molex connector to the psu. If the fans do not turn on, your fans may be not be receiving enough power, which I doubt or most likely they are broken.
Have you checked where they are connected to and if they are connected firmly? If one is CPU (processor) fan be sure to connect it to the 4-pin plug on your motherboard labelled CPU FAN, it can also be a three pin plug. If it's just a chassis fan, as pdxalex said, try the molex connectors (the 4 pin plug coming through a wire straight from the power supply). Otherwise, spare 3-pin or 4-pin plugs can be used. Whatever you do, don't leave your processor fan unplugged, and try not to unplug it in the first place.
