Watercooling how does it work?

Watercooling is all about removing heat from the processor as fast and as effeciently as possible. A standard heatsink uses copper (in most cases) to absorb heat into fins where the heat is dissapated into the air. Fans placed on heatsinks increces the air flow and improves dissapation.
As you may (or may not) know, water absorbs heat and stores heat faster and dissapates much better than air. So if there were some way to make the heat from the processor go into water, the overall cooling capacity will be improved.
In watercooling, insted of using fins to dissapate heat from a copper base, water is pumped into a block placed on the processor which absorbs the heat quickly and removes it quickly. This water that absorbed the heat then is pumped to a radiator. A radiator is a series of small water channels with many many cooling fins on it so that when water passes through it, the heat absorbed by the water can escape into the fins and then into the air. Basically, the radiator acts like a standard heatsink, but much better and with more cooling fins and capacity.
Other things found in a cooling loop are the reservoir which holds excess water waiting to be pumped through the system, and the pump, which actually moves the water so the waterblock gets a continous supply of water in which to dissapate heat into.
Get it? Hope this helps.

You can see a lot of watercooling rigs in the sticky at the top of the forums.
What more did you want to see? How a waterblock looks on the inside? Check out www.swiftnets.com/assets/images/products/MCW5000/mcw5000x630.jpg
As you can see, there are many little copper pillars that the water flows through. The water takes heat away from the pillers (which was absorbed from the processor through the bottom of the heatsink) and takes it out the other end.
That water that just absorbed the heat goes to a radiator that look something like this:http://www.hwlabs.com/products/blackicextreme.htm
Those are the basic components that absorb and dissapate heat in a water cooling system.

Does it circulate back in forth in the waterblock? Or in the radiator?
The answer to both questions is no. Water flow in watercooling loops is almost exactly like a river. There is one direction of flow, but many ways to get downstream. Water generally does go in one direction, but it spreads out and encompasses all avaliable space in the waterblock. Then it is forced back together at the oulet of the waterblock. Flowrates in the waterblock go at sometimes up to 4 Gallons per minute. Thats quite a bit of flow when you think about it going through such small spaces.
The water loops around... As in, it goes from the pump into the water block, out of the water block, in to the radiator, out of the radiator, and back to the pump. (Of course, most people have extra stuff in their water cooling, that was just a simple example.)
The water carries the heat from the CPU water block, to the radiator where it is removed using fans, and then the water goes back to the CPU (going through the pump, of course). It's an endless loop of the same water. Everything has an input and an output.

It's exactly like how a car's cooling system works, minus the thermostat.
Basically your using water in place of air. The downside of this is how to cool the water back down. This is where either massive resevoirs or radiators come to play.
Now for the water to work, it has to move...much like air has to move in traditional aircooling. Your pump is waht does this job.
Now, there are many fill methods...resevior, closed loop, t-fitting, or a valve based setup. Each of these have their own merits and pitfalls. The resevior setup is the closest to a car's layout if you care anyhting about that.
Man....all this is making me want to build a scale car into a PC, and have the radiator as the radiator of the engine...

Informative thread.
So...
Pump
->
Waterblock
->
Radiator for cooling
->
Back to pump
Where would a Reservoir fit in here, and what does it do? (Obvious I know, but an explanation in terms of watercooling would be useful).
Where would a heatercore fit in here? Is it the same thing as a reservoir?
What other components are there in water cooling?

It doen't really fit in at a specific place, different people put them in different orders. Personally, I'd go pump > reservoir > radiator > CPU block > pump, but different people do it different ways.
A reservoir helps to make refilling the system with water easier, plus you can keep an eye on water levels easier with a res.
A heatercore does the same thing as a radiator, not a reservoir.

Heatercore is the same as a radiator as far as functionality.
Usually the resevoir goes right before the pump, since the resevoir often has air in it, and that small amount of air supposedly can negatively affect flowrates if it's on the pressure side of the pump.
Other components is tubing, get whatever fits your gear.
Hose clamps. Unless you run speedfits or self-clamping fittings, make sure you have plenty of hose clamps.
Any extra waterblocks you may want: extra CPU, northbridge, videocard...there are even hard drive blocks, and I know of a wter-cooled PSU as well.
Flow meters are ok, but I never saw a need for them.
Also for some pumps, namely ones that run off mains power (wall plug), you should get a relay to allow for the pump to turn on at the same time as your PC. This ensure that you don't forget to turn the pump on or anything similar.
