Integrated heat dissipation
 

Another consideration is the level of noise produced by the fan. While fans are often used in outdoor or industrial settings where noise levels are not a concern, some applications may require quiet operation. Fans with lower noise levels are available and can be beneficial in environments where noise is a concern.
