Different parts required for watercooling explained
Water Cooling
For the more advanced or overclocker user who is comfortable with installing a kit from scratch or knows how it works to avoid any problems. You are basically installing a water pump / radiator style system into a case in a similar way that a car uses. Tubes, water and pumps either need to be installed in or next to your system.
Why cool a PC with water instead or normal air cooling? The main reason is that water cooling provides better cooling, the next is that by water cooling the system will run far quieter than with normal fans.
With these systems you can control the cooling system so much more and as a result push your system further by overclocking components further to squeeze every bit of speed increase out of the system.
Water cooling parts:
CPU Block - This transfers the heat from the CPU, essentially it is a block often copper with water running though the centre. The block has a hollowed interior where the water runs through and typically there are a number of barbs on the cooler which are used to connect the tubes to.
North Bridge Block - This part is often an optional addition and is normally used to replace the fan in an air based system. The chip itself does not run too hot unless you are looking to over clock.
Video Card Block - Again optional is designed to replace the cooler on your graphics card. Similar to the CPU block, this works in the same way be being secured onto you graphics card.
