Having taken apart pretty much every brand of laptop and many models I can say this is new, to the laptop market. The original idea was to use a fan to pull the hot air off the components and push it outside.
Most laptops would use a single, flat heatpipe that would cover the critical components, normall the CPU but sometimes the CPU and the GPU. Then a fan would pull the heat off of the end of the heatpipe and out the side or back.
This instead uses an idea that desktop PCs has used for a long time. Pull in cool air, push it over the components then out the back again. Enthusiast PCs normally pull air in the front and side and then up and out the back and top. It creates air flow which laptops have lacked.
I hope this idea sticks though. Laptops parts die faster due to heat, especially HDDs. Intel always tries to find a better way to cool, such as with BTX where the CPU sits in front of the PC where the air is cooler. Unfortunatley BTX didn't pass so it was only used by the OEMs in a small number of models for a short while.
