Abstract
Cooling system fan noise reduction can be best achieved by a combination of aerodynamic design and control of the fan environment. Design for minimum noise is a complex procedure that requires the optimization of fan geometry and fan environment, maximum efficiency at the operating point and the lowest possible blade tip speed. Good noise measurements are essential to research and development activities in fan noise reduction. Computer aided design techniques are required to optimize the fan.
