1. A gas turbine engine comprising: a first source of air to be delivered into a core of the engine, a second source of air, distinct from said first source of air, and a controller configured to separately control first and second fans, each delivering air into respective first and second conduits
1. A gas turbine engine comprising: a first source of air to be delivered into a core of the engine, a second source of air, distinct from said first source of air, and a controller configured to separately control first and second fans, each delivering air into respective first and second conduits connected to distinct auxiliary applications;wherein said first and second fans are separately controlled to deliver distinct amounts of air into said first and second conduits, said controller programmed to deliver distinct amounts of air into said first and second conduits as flight operation changes, to provide sufficient quantity of air to said distinct auxiliary applications as flight operation changes;wherein said first and second fans are positioned to be downstream of a heat exchanger and in fluid communication with the heat exchanger; andwherein the first fan, the second fan, and the heat exchanger are located radially outward of a compressor of the gas. 2. The gas turbine engine as set forth in claim 1, wherein said heat exchanger is an air to oil cooler. 3. The gas turbine engine as set forth in claim 2, wherein one of said applications is for cooling a pitch control mechanism for a propeller included in the gas turbine engine. 4. The gas turbine engine as set forth in claim 2, wherein at least one of the applications is for cooling a gear reduction incorporated into the gas turbine engine to drive a propulsor. 5. The gas turbine engine as set forth in claim 4, wherein said air to oil cooler receives oil which is utilized to cool said gear reduction for driving said propulsor. 6. The gas turbine engine as set forth in claim 2, wherein at least one of said applications is for an environmental control system. 7. The gas turbine engine as set forth in claim 1, wherein at least one of said applications is for an environmental control system. 8. The gas turbine engine as set forth in claim 1, wherein at least one of the applications is for cooling a gear reduction incorporated into the gas turbine engine to drive a propulsor. 9. The gas turbine engine as set forth in claim 1, wherein one of said applications is for cooling a pitch control mechanism for a propeller included in the gas turbine engine. 10. The gas turbine engine as set forth in claim 1, wherein a propulsor is provided in the gas turbine engine. 11. The gas turbine engine as set forth in claim 10, wherein said propulsor is driven by a propulsor turbine through a propulsor drive shaft that is downstream of a turbine section driving a compressor section. 12. The gas turbine engine as set forth in claim 11, wherein said turbine section including a first and second turbine rotor, and said compressor section including a first and second compressor rotor with said first turbine rotor driving said first compressor rotor, and said second turbine rotor driving said second compressor rotor. 13. The gas turbine engine as set forth in claim 11, wherein said propulsor is at least one propeller. 14. The gas turbine engine as set forth in claim 13, wherein said first turbine rotor driving said first compressor rotor through a first shaft and said second turbine rotor driving said second compressor rotor through a second shaft, with said first shaft surrounding said second shaft, and said propulsor drive shaft being spaced axially further into the engine relative to said first and second shafts. 15. The gas turbine engine as set forth in claim 10, wherein said propulsor is a propeller.
