A Chinese company called Waffer has thought of a new way to control this heat, in the form of a small air conditioner. This unit cools outside air and forces it into the computer, benefiting the entire system. This principle is the same used in electric drink coolers for automobiles. These coolers work decently to refrigerate food because they also are completely insulated like a thermos. They also contain items that do not generate their own heat. So this idea may not work as well for a PC, as a PC case by nature should not be insulated and also generates additional heat.
