The need for this kind of cooling technology is being driven by the thermal challenges that are associated with ever increasing processor speeds. As CPUs and associated electronics become faster, and hotter, the ability to dissipate this heat with conventional air cooling devices is becoming increasingly difficult. Even when the heat can be removed with active air cooling devices, the price that must be paid with noisier acoustics (due to the high fan speeds required) is often unacceptable to both the system designer and the product end user.
With increased thermal efficiency provided by a liquid heat transfer medium, liquid circulation cooling does offer significant cooling advantages over conventional air cooling. Presently, however, there are still several key limitations of liquid cooling that have prevented its widespread adoption by the majority of the mainstream desktop and notebook computer makers.
