From Turbo Boost's description, it seems the clock speed is adjusted according to temperature so that the computer doesn't overheat. Does this mean that by using the computer in an air conditioned room will allow better/longer/higher turbo boosting since the air entering the fan will be colder? What about cooling the base of the laptop? Another question about turbo boost: Undoubtedly, while turbo boosting, the computer will get hotter, and at a certain temperature it will begin to throttle down. Suppose a program requires 2.5Ghz to run smoothly. Does this mean that I can only run the program for a certain amount of time before it becomes "choppy?" i.e Does this mean performance will get worse and worse the longer you use a program? This doesn't seem like that big of a problem with macbook pros which have a base clock of 2.6ghz since turbo boost only increases clock speed by ~40%. In the case of the air, turbo boost almost doubles the clock speed! Can anybody say from personal experience whether or not the throttling has a big impact on apps that require consistent performance such as games (since the iGPU also depends on the cpu clock speed)?
