A fan assembly includes a fan, a first plate, and a rack. The fan includes at least one power line. The first plate is mounted on one side of the fan. The first plate mounts an adjustable resistor assembly thereon. The adjustable resistor assembly connects the at least one power line to a power source. The adjustable resistor assembly includes a first resistor and a slider. The slider includes a conducting point. One end of the first resistor is connected to the power source. The at least one power line of the fan is connected to the conducting point. The slider is capable of sliding on the first side plate to have the conducting point contacting different parts of the first resistor to vary the resistor value of the adjustable resistor assembly. The rack is capable of receiving the fan with the first plate mounted therein.
