1. A modular fan system configured for use in an air-handling system configured to deliver air to a ventilation system for at least a portion of a building, the modular fan system comprising: a plurality of modular units configured to be stacked adjacent to one another in at least one row or column to form an array for use in an air-handling system configured to deliver air to a ventilation system for at least a portion of a building, the modular units each including a chamber having a front end and a back end, the modular units are stackable adjacent to one another in the array, such that, when the modular units are stacked, the chambers open at the back ends into a common discharge plenum where the air mixes;motors and fans positioned in the chambers of the modular units, the fans located to take in air from the front ends of the corresponding chambers and to discharge air from the back ends of the corresponding chambers, the motors having a corresponding first speed when driven at a frequency of 60 Hz, the fans being configured to deliver an air flow amount based on a speed of the corresponding motor; anda speed controller to operate at least one of the motors at a speed that is greater than the first speed to deliver an associated air flow amount from the corresponding one of the fans. 2. The modular fan system of claim 1, wherein the speed controller operates the at least one of the motors at a speed that is less than or equal to the first speed to deliver an associated air flow amount from the corresponding one of the fans. 3. The modular fan system of claim 1, wherein the first speed constitutes a nameplate rated speed. 4. The modular fan system of claim 1, wherein the first speed is 1750 RPMs. 5. The modular fan system of claim 1, wherein a wheel diameter of the fans substantially equals or is between 12 inches and 44 inches. 6. The modular fan system of claim 1, wherein the wheel diameter of the fans substantially equals or is between 12 inches and 25 inches. 7. The modular fan system of claim 1, wherein spacing between said fans is between 60% and 20% of said fan wheel diameter. 8. The modular fan system fan array fan section of claim 1, wherein at least a portion of the chambers including sound attenuation layers that extend along at least a portion of an interior surface of the corresponding chambers, at least a portion of the sound attenuation layers being positioned between the chambers adjacent to one another. 9. The modular fan system of claim 8, wherein each of the chambers include top, bottom, and sides having the sound attenuation layers provided thereon. 10. The modular fan system of claim 8, wherein the sound attenuation layers include a perforated facing and at least one layer of insulation material. 11. The modular fan system of claim 8, wherein each of the chambers has a front end and a back end, wherein the fan units are oriented such that the fans are located proximate to the front ends of the chambers and the motors extend toward the back ends of the chambers. 12. The modular fan system of claim 8, wherein the sound attenuation layers are located along, and enclose, the top, bottom and sides of the fans and motors in the corresponding chambers. 13. The modular fan system of claim 8, wherein the fans constitute plenum fans. 14. The modular fan system of claim 13, wherein the speed controller includes a variable frequency drive. 15. The modular fan system of claim 13, wherein the fans are coupled to the motors in a direct drive connection. 16. The modular fan system of claim 1, wherein the fan array includes a number of fan units sufficient to at least meet a total air handling requirement for at least the portion of the building, and wherein the speed controller is sized to meet a power consumption of the fan array needed to meet the total air handling requirement. 17. The modular fan system of claim 1, wherein the fan units direct air into a common area of a discharge plenum where the air combines before exiting the discharge plenum. 18. The modular fan system of claim 1, wherein the first speed constitutes synchronous speed. 19. A method of providing a modular fan system configured for use in an air handling system to supply air to a building, the air handling system including an air handling compartment having a discharge plenum configured to deliver air to a ventilation system for at least a portion of the building; the method comprising: providing a plurality of modular units configured to be stacked adjacent to one another in at least one row or column to form an array for use in an air-handling system configured to deliver air to a ventilation system for at least a portion of a building, the modular units each including a chamber having a front end and a back end, the modular units are stackable adjacent to one another in the array, such that, when the modular units are stacked, the chambers open at the back ends into a common discharge plenum where the air mixes;positioning motors and fans in the chambers of the modular units, the fans located to take in air from the front ends of the corresponding chambers and to discharge air from the back ends of the corresponding chambers, the motors having a corresponding first speed when driven at a frequency of 60 Hz, the fans being configured to deliver an air flow amount based on a speed of the corresponding motor; andconfiguring a speed controller to operate at least one of the motors at a speed that is greater than the first speed to deliver an associated air flow amount from the corresponding one of the fans. 20. The method of claim 19, further comprising configuring the speed controller to operate the at least one of the motors at a speed that is less than or equal to the first speed to deliver an associated air flow amount from the corresponding one of the fans. 21. The method of claim 19, wherein the first speed constitutes a nameplate rated speed. 22. The method of claim 19, wherein the first speed is 1750 RPMs. 23.
