Exceptionally Silent Operation 
Achieved by a silence-optimized 120mm be quiet! fan
The silence-optimized 120mm be quiet! fan is thermally governed to strike the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, enabling best-in-class quiet functionality and the almost inaudible operation that be quiet! is famous for.
