English: Schematic of a regular liquid cooling system for PC's. The schematic was mainly based on the text at http://computer.howstuffworks.com/liquid-cooled-pc3.htm/printable (section "Liquid Cooling System Reservoirs and Tubing"). Also see http://www.tomshardware.com/reviews/a-beginners-guide-for-watercooling-your-pc,1573-2.html

Note that the fan simply blows cold air unto the radiator and isn't connected with a water tube.

Also note that:

• several water blocks can be used as well, the water blocks then connect to each other -read the howstuffworks section mentioned-
• instead of a radiator specifically made for use in PC liquid cooling systems, car heater cores too can be used -read the howstuffworks section mentioned-
• it is also possible to make a similar PC liquid cooling system eliminates either a pump or the fan or both (passive system).
