Branched paraffins formed as a hydrogenated reaction product of one or more linear alpha olefins (LAOs) oligomerized with a BF3 catalyst system and comprising at least about 90 wt. % branched paraffin dimers may have advantageous heat transfer properties. Heat transfer fluids comprising the branched paraffins may be placed in contact with a heat- generating component, such as those found in electric vehicles, battery systems, and other locations in need of thermal management. Branched paraffin dimers formed from one or more LAOs having about 8 to about 12 carbon atoms may collectively have a Mouromtseff Number ranging from about 10,000 to about 16,000 kg/(s2.2.m0.6.K) at 80° C., a thermal conductivity at 80° C. of about 0.125 W/m.K or higher, and a flash point of about 140° C. or higher.
