The higher the voltage and frequency, the higher the power and the higher the temperature. Such active power will increase the CPU to certain temperature under certain load for a given cooling.

Since carrier mobility decreases as temperature increase beyond certain temperature due to lattice scattering, transistor switching slow down as temperature increases. So the

**frequency f of a CPU varies inversely with the temperature**, or df / f = - k dt, mathematically, where f is frequency, t is temperature, and k is a constant.

The balancing of these two opposing actions, or the intersection of the voltage-frequency curve and the temperature-frequency curve of a CPU characteristic

**naturally** determines the final stable voltage/frequency/temperature operating point. If overclocking is done properly, the maximal overclocking should settle naturally at certain frequency, voltage and temperature, as desribed above, below the maximum absolute rating of voltage and temperature (as seen from Tbred/Barton, ...).

**A perceived stable voltage and temperature setting may not be necessary after all**, if the voltage, temperature, frequency variations are monitored properly and adjusted incrementally.
