A method of noise management in an electric heavy vehicle, including determining a noise threshold and corresponding reduced target speed for a cooling fan providing cooling of a propulsion/braking system of the vehicle, obtaining look-ahead data pertinent to an upcoming section of a road, and to determine a speed profile for the vehicle such that a cooling requirement of the propulsion/braking system does not exceed a cooling capacity of the cooling fan running at the reduced target speed. The method further includes, while driving along the section of the road, controlling the cooling fan not to exceed the target speed, and controlling the speed of the vehicle in accordance with the speed profile. A corresponding control system, heavy vehicle, computer program and computer program product are also provided.
