Abstract: The water cooling system for computer components is a system for removing heat from the heat-producing components of a computer, or other electronic, system. The water cooling system for computer components employs one or more water-block type heat exchangers to remove heat from electronic circuit components, transferring heat to a fluid coolant. A heat dissipating device, in the form of a tubing coil, dissipates heat from the coolant. A coolant pump circulates a fluid coolant from a coolant reservoir, through fluid conduits interconnecting the water-block heat exchangers and the heat dissipating device. The water-block type heat exchangers are formed from a single, solid block of material, and have an internal water passage directing the fluid coolant through the center of the block to apply maximum cooling to the center of an electronic circuit components where the maximum heat is produced.
