We first heard about ionic winds cooling down computers by 250% in 2007. Two years later, Tessera—a chip-packing company—has modified the technology so that it would fit into a working laptop.
How ionic winds differ from typical cooling system is that by ionising the air and passing it over a processor chip, the ionised air increased airflow on the surface, thus creating a cooling breeze over a hot microprocessor (as illustrated above).
Apparently, Tessera's cooling system not only consumes half as much power as other conventional laptop fans, but also can eliminate up to 30% more heat as well. It's pretty much the same technology from a couple years ago, yet reduced in size to fit your personal, portable needs. [Technology Review via BBG]
