If the cooling system is critically low on coolant the engine may be running very hot, that may be the reason the cooling fans operate for an extended period.

Beyond what Nevada suggested, the thermostat could be stuck closed. Or the temperature sensor could be bad. Has the temperature gauge been reading higher than usual?
