Cooling

To guarantee reliable operation across the entire operating temperature range and longer lifetime, ensure an adequate cooling of the card:

The cooling is improved by a higher air flow circulating around the board. This air flow is increased, for example, by using computer case fans.
Avoid placing a card next to other heat dissipating boards.
