Fan grill contributes to fan noise and airflow

Fan grill is usually made by low carbon steel and is often underestimated in terms of their contribution to both fan noise and airflow. It would stand to reason that the more raw material present on the grill would cause a more restricted airflow, which in turn would cause a drop in airflow and a rise in noise. In our experience however, the shape and pattern of the grill can have a huge impact on noise due to the different types of turbulence that can be caused.
While the number of possible fan grill designs is essentially limitless, we will be testing some of the most common designs that come included with fans and chassis, as well as some popular after-market designs. A few of these fan grills can also found cut into window panels or stamped directly onto the metal body of a chassis itself by the manufacturer.
