"Q : Are custom fan grills purely aesthetic in nature? Is it always a trade-off from looks to air flow performance? Is there such a thing as having air flow with custom fan grills that one could achieve levels that stock fan grills can?

A : I finally get to tackle this one for the sake of the hardcore heat people! The truth is these grills were never intended for guys who worry about 1 degree this way or that in case temps. Most cases have horrible pre-stamped steel/aluminum grills built into the case. My grills are made for those people to either hide or eliminate those ugly stampings. Some of our parts probably have the same airflow as any other stock grills, I could not tell you which. I imagine we could get tests done to show cavitations patterns on the air and or flow quantity but I don't think the average desktop case needs to be engineered at NASA for home use. Here we have a division in modding a lot like in cars, your stripped down BC mile guys and the guys who build show car hotrods. I think aesthetics and functionality are important , but trying to eek out one more horsepower by removing the back seat is not my bag."
