Cooling electronics with fans and blowers
Fans and blowers used to cool electronic devices work in much the same way as any other fan or blower, but have specially designed features that optimize the characteristics of the cooling assembly. They are designed to balance power consumption and flow to work efficiently within the device. This is a particular concern for battery powered applications.

The fan draws in air and blows forward along the same axis, while the blower draws in air and ejects through the turyers in different directions. This provides greater flexibility for fan placement as it can be mounted either on the top of the heat sink or on the side of the standard airflow. On the other hand, the blower provides lower profile and hot spot cooling. The blower also has a high static pressure that allows it to push air through the fins more forcefully. Heat sinks for forced convection cooling of fans or blowers typically have a high heat sink density.
