An arrangement for controlling cooling of a gaseous medium for a supercharged combustion engine (2): A low temperature cooling system with a coolant, a coolant pump (27) for circulating the coolant in the cooling system. A cooler (10, 15) in which a gaseous medium which contains water vapour is intended to be cooled by the coolant in the cooling system. At least one sensor (33, 35) for detecting a parameter which indicates whether the gaseous medium is cooled so much that there is ice formation or risk of ice formation in the cooler (10, 15). A control unit (31) for receiving information from the sensors (33, 35) and for deciding whether there is ice formation or risk of ice formation in the cooler (10, 15) and, if so, for controlling the coolant pump to be temporarily switched off or circulate a reduced flow of coolant through the cooler (10, 15) relative to a normal flow. There are preferably two coolers in series and a respective high temperature cooling system for the first cooler and a low temperature cooling system for the second cooler.
