In the case of a cooling fan, in-rush current can occur when the fan is first powered up and the motor starts to spin. The in-rush current for a cooling fan will depend on several factors, including the size of the fan, the voltage and current rating of the power supply, and the design of the motor. Typically, the in-rush current for a cooling fan can be several times higher than the normal operating current. It's important to take the in-rush current...
