The AirCon is not a traditional Air Conditioning unit like you would find in your house or car. There are no compressors, condensers, or Freon in the AirCon. The AirCon actually is a combination of two heat sinks, two fans, and a thermoelectric cooler, also known as a peltier. Peltier’s have been used to cool CPUs for quite some time by hardcore overclockers. Here is a brief description of what they are and how they work:

Peltier devices, also known as thermoelectric (TE) modules, are small solid-state devices that function as heat pumps. A "typical" unit is a few millimeters thick by a few millimeters to a few centimeters square. It is a sandwich formed by two ceramic plates with an array of small Bismuth Telluride cubes ("couples&quot in between. When a DC current is applied heat is moved from one side of the device to the other - where it must be removed with a heatsink. The "cold" side is commonly used to cool an electronic device such as a microprocessor or a photodetector.

So what we have is a thermoelectric cooler sandwiched between two aluminum heat sinks, each with its own fan. Then throw in a digital display to show the temperature of the air flowing through the unit, a switch to control the two operating modes, and a slide mounting system that occupies a 5.25” drive bay, and you have the PC AirCon PAC 400.

It'd be much more efficient to just have the peltier in the CPU heatsink itself.

yea, but you wouldnt imagine how many people would actually pay that much for the bragging rights to say that they have an ac unit in their case.

or i guess you could strip the unit, ant take the peltier and put that on the cpu, then i guess the case would be worth it.

to cut a long thread short. it is not a good idea to do this with ice. as someone else pointed out if you have any inclination to do this use dry ice. i can't promise there won't be moisture from condensation but at least dry ice does not melt into water. dry ice is also considerably cooler than standard ice.
