A cooling system for a computer (10) includes a thermoelectric cooler (20) attached to a side panel (14) of the computer, an internal heat sink (30) attached on an electrical component, a cooling fan (52) attached on one side of the internal heat sink, a fan duct (50) connected between the thermoele

A cooling system for a computer (10) includes a thermoelectric cooler (20) attached to a side panel (14) of the computer, an internal heat sink (30) attached on an electrical component, a cooling fan (52) attached on one side of the internal heat sink, a fan duct (50) connected between the thermoelectric cooler and the cooling fan, an exhaust fan (80), and an external heat sink (70) attached on the side panel opposite to the thermoelectric cooler. When electrified, the thermoelectric cooler is polarized to generate a hot surface in contact with the side panel and a cold surface facing toward an interior of the computer. The cooling fan sucks cold air from around the cold surface, and blows the cold air through and over the internal heat sink. The air is then expelled from the computer by the exhaust fan, and directed toward the external heat sink.
