The ticking you hear sounds like an exhaust leak. As far as the temp switch, it won't control the fans. Its purpose is to tell the computer the coolant temp and ambient temp so the computer knows how rich / lean to make the fuel mixture. Have you checked the fan relay? Have you checked to make sure the fan motors are good?
