The fans will come on when the AC is on. It is designed that way. If they don't come on at any other time, I would first make sure your engine is getting hot enough to turn them on. Have you had any overheating issues that would indicate they are failing or does your temp stay in the normal range when you drive? I don't know about the thump you describe but you may want to inspect your tires on that side and look for distortions in the tread or bubbles on the sidewalls.
