Abstract:
1. A method of cooling a radiator of an internal combustion engine steps comprising: providing a plurality of fan assemblies wherein each fan assembly has a housing with an interior containing a fan blade rotatably connected within the housing and an exterior having six sides to form a hexagonal perimeter; providing aerodynamic arcuate surface to transition from a hexagonal inner diameter on the back of the fan assembly to a circular inner diameter on the front of the fan assembly; placing a first side of a first fan assembly adjacent a first side of a second fan assembly and a first side of a third fan assembly adjacent to a second side of the first fan assembly and a second side of the third fan assembly adjacent to a second side of the second fan assembly to form a cluster of fan assemblies; and placing the cluster of fan assemblies adjacent a radiator to control the air flow over the radiator and cool the radiator.
