|NEC Corporation announced the development of the world's first slim sized water-cooling module for notebook personal computers that employs a piezoelectric pump driving method. This water cooling-module enables a highly advanced, slim sized, notebook PC with minimal operating noise.
The water-cooling module uses a piezoelectric pump to drive the cooling liquid. This newly structured water-cooling module is developed by integrating the pump and the tank with the aluminum radiation plate that contains the water circulation channel.
According to NEC it still produces about 30dB of noise, so real quiet it is not. But if it really works like they plan, then it will be able to cool down your laptop I think. Lets hope that it does not leak!
