Video: CoolTech Fan – Dual Bladed Tech Demo

The new ASUS GeForce GTX 670 DirectCU Mini is more than just a tiny graphics card. To achieve its size the ASUS R&D team had to design an entirely new fan, dubbed CoolTech, to push air down and out more efficiently without requiring more fan speed (and thus, noise). The blade design is two-stage. The inner radial blade sucks air inwards and blows it out towards the curved, downward facing outer blades. Compared to a traditional, single curved fan blades which blow air in all directions, the new CoolTech design forces more air downwards so it spends more time in the heatsink. The effect is clearly shown in the video below as the rice grains are moved very quickly and easily.
