Increasing the processor frequency is accomplished by increasing the CPU’s thermal design power (TDP), which in turn increases the heat concentration on the silicon die. As long as the CPU cooler can dissipate enough heat to maintain the critical CPU junction and case temperatures, a CPU can be safely over-clocked. The problem is, today’s CPU air coolers do not have a lot of headroom to cool a CPU beyond the rated TDP. This is especially true in harsh computing environments. Asetek's liquid cooling solutions provide superior CPU cooling – providing a safe margin for over-clocking.
