The Base Concept
A liquid-cooling system for a PC works a lot like the cooling system of a car. Both take advantage of a basic principle of thermodynamics - that heat moves from warmer objects to cooler objects.
A car's cooling system circulates water, usually mixed with antifreeze, through the engine. Hot surfaces in the engine transfer their heat to the water, cooling themselves off in the process. This warm water is pumped through a radiator, which has a large amount of surface area. This radiator warms up, thereby warming up the surrounding air. A fan on the radiator then pushes the warm air away from the radiator, and out of the car.
Most computers dispel heat with heat sinks and fans. Heat sinks are basically pieces of metal that provide lots of surface area for the air to touch. The chip warms the heat sink, the heat sink warms the air, and the fan moves the warm air out of the PC case. They look like flat pieces of metal with a bunch of small fins.
This system works most of the time, but sometimes, electronic components produce more heat than simple air circulation can remove. High-end chips can sometimes overload an air-cooling system. So can chips that have been overclocked, or manually set to work at faster than their default speed.
Water has a higher thermal conductivity than air, meaning it can move heat faster than air can. Water also has a higher specific heat capacity, meaning can absorb more heat before it starts to feel hot.
There are two reasons why a computer might need the increased thermal conductivity and heat capacity of water:
1) Its electronic components produce more heat than the air around them can absorb - The components inside your computer need more cooling than air alone can provide
2) The fans required to move enough air to cool all the components make too much noise or use too much electricity - You want your system to be quieter
How It Works
PC water cooling uses a combination of "water blocks", radiators, fans, coolant reservoirs, pumps, hoses, and connecting fittings to cool your computer. Water blocks are pieces of heat-conductive metal, like copper or aluminum, that are filled with hollow tubes and channels.
The bottom of the water block is a flat piece of metal that sits directly on top of the chip being cooled. Thermal paste between the chip and the block improves the heat transfer between the two surfaces. The chip heats the block, and the water absorbs the heat as it flows through all the channels.

A Note From Us
Higher-end custom water cooling packages require quite a bit of technical information from you, due to the complexity of the higher-end cooling packages, and the need to ensure compatibility.
As such, please give us time to compile the package. We work to ensure you are fully satisfied with your cooling solution.
We place all water cooled computers under extensive leak testing before delivery. We take leaks extremely seriously, as they could be potentially catastrophic to the electrical components.
