a peltier is a device that uses alot of energy to create a really cold and really hot side, thus allowing you to cool a cpu to extreme temperatures.

The cold plate is designed to spread out the heat of the cpu across the peltier i believe. If you dont have a peltier then it wont prove helpful, it actually might hurt your temps since the heat would have to go throught more material before it got absorbed by the water.
 
Dont bother as of now, if your actually interested do some research.

Cold Plate Materials and Thickness

Cold Plate Description
A cold plate is one of the components of a cooling system utilizing thermoelectric coolers (TECs or Peltier Effect modules) to reduce CPU temperatures. Because TECs of a useful heat capacity are physically larger than the die being cooled, it is necessary to insert a so-called "cold plate" between the small hot die and the much larger cold side of the TEC to utilize the heat pumping capacity of the overhanging area.

This is precisely the same function that the base of an air-cooled heat sink serves - to distribute the heat to the fins from which it will be removed by forced convection. And for this reason, the cold plate material and thickness considerations apply generally to air cooled heat sinks as well.

That's a bit about coldplates. Heat does not conduct across the cold side of a peltier, so in order to use the power of the entire pelt instead of a small CPU die sized area, you use a coldplate.
 
A peltier is not part of any standard water cooling system. With a standard watercooling system you only need a waterblock to go on your CPU. Not a coldplate, peltier etc.

Parts of watercooling system

Pump
CPU Waterblock
Radiator
Resivoir or Tline
tubes
tube fittings
GPU waterblock (optional)
Northbridge waterblock (optional)

anyone feel free to expand on this list if I missed anything

heres a diagram of a standard tline setup

nope all works, peltiers are only if you want to walk on the "wild side" but you need a whole nother power supply for it, which add up if you are to lazy to build one yourself, usually more trouble then they are worth
 
baisically, peltiers will cool your system further more provided that there is a sufficient cooling.

Normally people will add WCing since its more effective than air cooling.

Most people decide not to walk that path due to
1. Another power supply
2. condensation problem
3. headache...
