Fans are a great way to keep things cool. The ability for air to cool an object is directly dependent of the air itself – so being able to move fresh cool air in to an enclosure or over a high heat component like a regulator, motor driver, or processor can make a big difference in its performance and longevity.

This basic 12V DC fan measure 40 x 40mm and is about 10mm thick. The fan is very quiet and moves approximately 20CFM.
