		Peltier coolers, also known as thermoelectric coolers, are solid state heat pumps that, with the application of electrical current, transfer heat from one side of the device to the other.
		It's actually a class of coolers, and many different models exist from many different manufacturers (the one Caesar reviewed was a Peltier cooler from Swiftech).
		The Peltier Effect was discovered in 1834 by a French watchmaker and physicist by the name of Jean Charles Athanase Peltier.

	Peltier Basics
		Let's assume we have a peltier which has the capability to move 50 watts of heat from the cold side to the hot side.
		Even if you don't have all the variables, if you are interested in buying a commercial peltier that is rated at 32 watts to use on a CPU that generates 40 watts, the peltier will not cool; it will probably wind up generating more heat to the CPU than a good air-cooled heatsink.
		The "Peltier from Hell" is a good example of a commercial peltier that is downright dangerous because it is undersized relative to the heat load and is unable to handle the heat load.

		The inherent danger of a Peltier cooler is if the fan that cools the Peltier cooler or the Peltier cooler's fan breaks down, then the heat that is generated by the cooler will cause some real damage, because it is so hot.
		More advanced Peltier coolers are able to solve this problem by delaying the start of the Peltier cooler to either start up after a certain amount of time, or to start up after the CPU reaches a certain temperature.
		Again, more advanced Peltier coolers tend to avoid this by starting up after some amount of time, or after the CPU has warmed up a bit, so the CPU's heat is able to offset the chilly temperature decrease induced by the Peltier cooler.

	Frequently Asked Questions (FAQs) KeyWords:(Thermoelectric Cooler TEC Peltier)
		Thermoelectric coolers are solid state heat pumps that operate on the Peltier effect, the theory that there is a heating or cooling effect when electric current passes through two conductors.
		The heat is carried through the cooler by electron transport and released on the opposite ("hot") side as the electrons move from a high to low energy state.
		The heat pumping capacity of a cooler is proportional to the current and the number of pairs of n- and p- type elements (or couples).

		The MC1000 Peltier Cooler was made with people like me in mind, people who enjoy tweaking and trying new things that improve performance just as much as they enjoy the performance gain they get.
		Peltier coolers, sometimes called thermoelectric coolers (or TECs), are an electric mystery to many.
		Discovered in 1834 by a Frenchman named Jean Peltier, the Peltier effect makes it possible to produce a kind of solid-state heat-pumping device, a device that can transfer heat from one side of a solid crystalline plate to another.

		Couple this with a PIB cooler that is good enough to remove the heat from the hotside and they have a cooler running 65 nanometre CPU".
		The peltier effect uses metallic plates sandwiching a flow of electricty which results in one side of the metal being extremely cold, and the other side being extremely hot.
		Peltiers are quite good at what they do but it comes at quite a cost with power consumption.

	Overclocker Cafe - Thermaltake SubZero4G TEC Cooler for P4 Review
		Peltiers (TEC units) have been known and used by computer enthusiast for a number of years.
		Previously, when using a Peltier, you needed to keep your CPU under somewhat of a load to keep temperatures from dropping too low.
		The slang for a Thermo-Electric Cooler is 'Peltier." This comes from a French physicist named Jean Peltier in the 1830's.

	NASIOC - Intercooler cooler (an idea) Peltier Cooler
		The fan on the Peltier is used to cool the HOT side inorder to reduce the amount of heat transfer to the cool side.
		Like a Peltier, water is also a good conductor of heat, and can be used to pump heat away from something that needs to be cooled beyond the ambient air temperature.
		If you assume the coolers are about 65% efficient and thermal efficiency of the fin system is about 50% (this is impossible to predict unless you know the flow characteristics of the system) then you would expect to use about 15 peltier coolers.

	Picking a Peltier
		Stick a cooler with one of the magic white ceramic semiconductor junction sandwiches in it on your CPU and the chip will be cool as a cucumber, allowing you to crank up the processor speed well beyond what you could manage with a mere passive cooler.
		But even allowing for these losses, this Peltier should be adequate for getting rid of the heat from any PC CPU on the shelves today, at any speed the CPU core can stand, as long as your power supply's adequate and the cooler the Peltier's moving the heat to is good enough.
		As long as the Peltier isn't loaded close to its limit, thought, it should still be able to make the CPU considerably colder than the same cooling system could make it without a Peltier, though.

	Overclockers.com---Alpha and Mushkin "Tundra" Socket 370 Peltier Cooler
		After my Socket 370 cooler comparison, where I beat up on the Mushkin cooler a bit, I got a couple of emails from the people at Mushkin saying that they have made some revisions to this cooler and are looking into more.
		I sandwiched the aluminum between the peltier and the CPU on the 5 volt unit and bent the clip so it would latch to the socket.
		The Alpha still beats the performance of this cooler so, with the drawbacks of added heat to the inside of the case (Peltiers create a BUNCH of heat on the hot side) and the added draw on the power supply, The Alpha at $30 with fan is still my choice for the Socket 370.

	Peltier Coolers
		In a nutshell, the Peltier cooler works like a tiny "air conditioner" for your processor, except it is a solid state air conditioner that works without any liquids or compressors.
		A Peltier device pumps heat from one of its sides to the other, so one is cool and the other warm.
		It keeps the processor at a low temperature, and since the Peltier cooler does not use moving parts, it is not subject to failure the way CPU fans are.

		However, when running this cooler, it should be noted that you must disable "sleep" or "suspend" modes which idle the CPU, because the cooler will then be too cold and possibly cause condensation.
		The main reason for this is that there are cooling solutions available that are almost as powerful, but don't have the disadvantages of Peltier coolers.
		In addition, when buying a Peltier cooler it is very important to get one that is "advanced" in that it will not begin to operate until a specified amount of time has passed or a certain degree of heat has been hit by the CPU.
