Curious noise

Newbie question number two. I can hear a pump or fan start up a few seconds after I start the engine. It is noticeable when cold, but quietens as it warms up. The noise it slightly irregular, and goes up a tone when accelerating and down a tone when decelerating.

Fuel pump, perhaps, but then why wouldn't it start as soon as I start the engine?
