New laptop fan cools with no moving parts

The nice folks over at Thorn Micro Technologies have developed an awesome new laptop fan – the RSD5. It is a solid state fan (no moving parts!) that uses an electrical current to generate airflow. More airflow, in fact, than standard mechanical fans.

While typical mechanical fans generate a breeze of 0.7 – 1.7 meters per second, the RSD5 can output a cooler 2.7 meters per second. What’s more impressive is that it stays completely silent while cranking out this kind of airflow.

One of the best things about this fan is that it’s the size of a microchip. The researchers who developed it are hoping to one day build these solid state fans directly into other chips, creating self-cooling processors and other chips that stay cool on their own. The new fan is very cool (no pun intended), but it would be interesting to see what kind of effect this would have on laptop battery life.
