1. A thermal management fluid for use in an electric system comprising:
a base oil as a major component, wherein the base oil comprises:
(i) a branch content of about 22 mol % to about 30 mol %, wherein the branch content is a tertiary carbon content of the base oil; and
(ii) a naphthene content of about 30 wt. % or less;
wherein the thermal management fluid has a thermal conductivity at kinematic viscosity of 5 mm2/s at least about 5% greater than a predicted thermal conductivity characterized by the following regression model equation:
TCPred=84.873*(BC)−0.17
wherein TCPred is the predicted thermal conductivity measured in mW/mK, and BC is the branch content of the base oil.
