To begin with, unless you are using a refrigerator-type cpu cooler the temperature of your cpu cannot be less than the ambient temperature
This is not true - moving air from a fan carries heat away more effectively than static air, so the processor can be several degrees below the ambient temperature, provided the fan and heatsink are reasonably clean. This is exactly why people use room fans in hot weather and we are given a "wind chill" factor in winter weather reports.
Nonsense. Yes, moving air will carry heat away faster than static air. But the device that you are cooling will not reach a temperature below the ambient air. You can approach the ambient temperature asymptotically, but never reach it. Your example of "wind chill" has to do with what is called "evaporative cooling", i.e. that if an object is wet (like the surface of your skin) and the water evaporates, the energy that goes into the phase change (evaporating the water) will be extracted from the device providing the water to begin with. Time for a basic physics class.
