Very Quiet Case Fan (4 3/4", 12v, DC) 

Innovative Design Enables Quiet and Efficient Ventilation 
The innovative design of the fan blades improves the airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimizing the noise level yet delivering the desired airflow and pressure. This is the quietest fan on the market!
