This small active fan is ideal for perfectly cooling your electronic projects in difficult environments. Its dimensions of just 2 x 2 cm and a low height of just 1.4 cm allow it to be used in well-known single-board computers such as Raspberry PI, Banana PI, Cubie and Co, but also in your self-developed boards or robotok projects. Installation is very simple. There is a special "adhesive layer" on the underside of the cooler. After removing the protective film, fix the cooler in the desired position.
