Engine cooling fans are typically controlled by a temperature sensor that monitors the engine's coolant temperature. When the temperature exceeds a predetermined threshold, the sensor signals the fan to turn on, often via a relay or directly through an electronic control unit (ECU). Some systems also incorporate variable speed control to adjust the fan's speed based on the engine's cooling needs for improved efficiency.
