strange noise from engine bay

Went to start my clio this morning started fine but along came a noise sounded like a clicking/clapping noise syncd with the revs. When the car warms up the noise disapears what could this be ? Car still drives fine somebody help

Hard to say without hearing/seeing the car but my guess... water pump

Sound kind of like and electric spark but constant and it speeds up if i rev the car and slows down with the revs after the car is warm the noise goes
