1. A graphics card assembly, comprising:
a bracket;
a graphics card module, assembled to the bracket and having at least one heat source;
a first fin set, assembled to the bracket and thermally contacting the at least one heat source;
a centrifugal fan, disposed beside the first fin set horizontally to generate a first air flow to dissipate heat from the first fin set;
a second fin set, assembled to the bracket, wherein the first fin set and the second fin set are on opposite sides of the centrifugal fan and at the same level;
a heat pipe set, in thermal contact between the at least one heat source and the second fin set; and
an axial flow fan, disposed on the second fin set to generate a second air flow to dissipate heat from the second fin set, wherein the first air flow and the second air flow are separated from each other, and the second air flow passes through the bracket and the graphics card module along the axial direction of the axial flow fan without changing the direction.
