Abstract: An information handling system EMI shield system couples to a circuit board to enclose an electronic device in a Faraday cage and includes a surface painted with a graphene paint to aid in dissipation of excess thermal energy from the electronic device. The EMI shield system has a frame that couples to the circuit board and interfaces with ground to define a boundary around an electronic device connector and has a shield that couples as a separate piece over the frame to enclose the electronic device. Graphene paint applied to some or all of the shield encourages rejection of excess thermal energy from within shield.
