But heating and cooling is not symmetrical. We can heat a processor much faster than cool it. So, if we need to cool a processor 10x faster than we can, just use 10x more processors, and switch them in order, to allow them cool after use in overclocked mode. Using this simple technique, frequency can be raised by few GHz, which is important for serial computations.
