This invention provides a fan adapter for electrically connecting a circuit board and a fan connection port. The circuit board has at least a fan pulse width modulation signal node, a first fan waveform feedback signal node, a fan power input signal node, a fan power output signal node, and a second fan waveform feedback signal node. The fan adapter includes a base and first to fifth electrical pins disposed on the base and equidistantly spaced apart in sequence, wherein the first to fifth electrical pins respectively have one end electrically connected to the fan pulse width modulation signal node, the first fan waveform feedback signal node, the fan power input signal node, the fan power output signal node, and the second fan waveform feedback signal node of the circuit board respectively, and respectively have the other end electrically connected to the fan connection port, thereby allowing a single fan adapter to be fit for use with various types of fan connection ports and to control conjoined fans or two fans.
