A fan sink that includes a dual impeller push-pull axial fan and a heat
sink to cool a hot electronic device is presented. The axial fan has a
hub motor, a first impeller that is radially proximate to the hub motor,
and a second impeller that is radially distal to the hub motor, wherein
the first impeller pushes air in a first direction and the second
impeller pulls air in a second direction. The heat sink is oriented
between the axial fan and the hot electronic device such that the hot
electronic device, the heat sink, and the axial fan are axially oriented,
wherein cool air is forced onto the heat sink by one impeller in the
axial fan, and wherein heated air from the heat sink is removed by an
other impeller in the axial fan.
