Abstract: The present disclosure relates to a method of controlling a fan 5 in a cooling system for a fluid-filled electrical device 1. The method comprises obtaining information about a device temperature of the fluid-filled electrical device from an internal temperature sensor 3. The method also comprises, based on the obtained device temperature information, determining that there is no need to run the fan for cooling the fluid-filled electrical device. The method also comprises obtaining weather information about an ambient temperature and ambient precipitation from a weather sensor comprising an ambient temperature sensor 13 and an ambient precipitation sensor 11. The method also comprises, based on the obtained weather information, controlling the fan such that it is running, to avoid build-up of snow or ice on the fan.
