A dataset is identified as a heat-intensive dataset based, at least in part, on the dataset being related to heat generation at a source storage device exceeding a heat rise limit. The source storage device hosts the heat-intensive dataset and the heat-intensive dataset comprises non-executable data. A first cooling area of a plurality of cooling areas is selected to accommodate the heat generation based, at least in part, on cooling characteristics of a plurality of cooling appliances of the plurality of cooling areas. The source storage device is associated with a second cooling area. A target storage device associated with the first cooling area is determined. The heat-intensive dataset is moved from the source storage device to the target storage device.
