A method and system that uses the flow of drilling fluid to cool electrical components in a downhole environment. A substantially cylindrical housing comprises a wall which houses at least one electrical component directly coupled to a thermoelectric cooling device. An opposing surface of the thermoelectric cooling device contacts a flow of drilling fluid through a hollow passageway in the wall.
