1. A heat dissipation device, applied to a computing unit, comprising:
a fan unit;
a signal receiving unit, configured to receive a satellite positioning signal and generate a signal strength according to the satellite positioning signal;
a time unit, configured to generate a real-time signal; and
a control unit, electrically connected to the fan unit, the signal receiving unit and the time unit, and configured to adjust a rotation speed of the fan unit according to the signal strength and the real-time signal;
wherein the signal strength is directly proportional to the rotation speed, and the real-time signal is inversely proportional to the rotation speed when the real-time signal is in a 24-hour time format.
