The controller 196 may regulate a rotation speed of the fan 192 based on the vertical height of the deflector(s). For example, the controller 196 may regulate the rotation speed of the fan 192 to increase as the vertical height of the deflector(s) increases. For example, the increase of the rotation speed of the fan 192 may be linear with respect to the increase in the vertical height of the deflector(s). The controller 196 may also regulate the rotation speed of the fan 192 based on a speed of the vehicle, a temperature measured by the temperature sensor 190, an external temperature, or a difference between the temperature measured by the temperature sensor 190 and the external temperature, and operate the fan 192 at the regulated rotation speed. For example, the controller 196 may regulate a rotation speed of the fan 192 based on a speed of the vehicle, a temperature measured by the temperature sensor 190, an external temperature, or a difference between the temperature measured by the temperature sensor 190 and the external temperature, and operate the fan 192 at the regulated rotation speed. For example, the controller 196 may regulate the rotation speed of the fan 192 to be linearly based on the difference between the external and internal temperatures. As another example, the controller 196 may regulate the rotation speed of the fan 192 based on whether the internal temperature exceeds a threshold temperature. If the internal temperature exceeds the threshold temperature, the rotation speed of the fan 192 may vary linearly with how much the internal temperature exceeds the threshold temperature. The rotation speed of the fan 192 may be regulated by the controller 196 in iterations. In a first iteration, the rotation speed of the fan 192 may be adjusted or regulated linearly based on the difference between the external and internal temperatures. Next, the rotation speed of the fan 192 may be adjusted or regulated linearly based on how much the internal temperature exceeds the threshold temperature. Next, the rotation speed of the fan 192 may be adjusted or regulated (e.g., linearly) based on the speed of the vehicle.
