This article presents a simple and effective approach of high performance microprocessor’s throughput enhancement. It aims at introducing of the notion of Reaction Time (RT). RT is a value that describes the time in which the TΔT control system is fed about the change in ambient cooling condition. Utilization of an additional temperature sensor enables to find out the information about dynamic change of cooling condition. The RT is used for approximating how fast TΔT system can react to the dynamic changes in surrounding environment. Using R-C thermal model in Spice environment, the Reaction Time is analyzed as a variable which is dependent on the convection coefficient and heat generated inside chip. Furthermore, RT values were evaluated versus the placement of additional temperature sensor on the body of a laptop. As results, better location of additional temperature sensor leads a rapid detection of change in surrounding condition in other words short Reaction Time. The advantage of this technique is that the changes of cooling condition can be quickly discovered. Consequently, the control system can react much faster in order to deliver the maximum processor’s throughput while guarantee the thermal safety.
