GM Research studies show that the peak efficiency and minimum noise operating points of a fan do not necessarily coincide. Therefore, the judicious use of both noise and performance characteristics is important in selecting the best fan design for a given application. These studies also show that decreasing tip clearance, decreasing pitch angle, and increasing chord at a given solidity will increase fan efficiency, while decreasing tip clearance, optimizing pitch angle, optimizing camber, and optimizing solidity will reduce fan noise.
