Zaward Golf Fans - High airflow with low noise!The reason these fans are called Golf Fans is not because they like nine holes now and again, but simply because their fins are similar to the surface of a golf ball! These dimples help a golf ball travel through the air with the least amount of air resistance to help the ball travel further. The principle of the Golf Fan is similar, but instead of trying to achieve distance the dimples help to cut down noise whilst increasing airflow. These fans include four metal fan screws, four rubber fan screws to reduce vibrational noise and a 3-4pin Molex converter.
