possibly temp sensor is out or disconnected. The ECU will go into default mode by running the fan constantly when it can no longer tell what the water temp is. I would start with the temp sensor and start tracking wires back.

it doesnt do it right away. i think it might be running warm but the fan is keeping it from over heating. any ideas on it running warm?
