Elmer, I took the Register article to imply something better than a common fan cooled heat sink, which hardly rates the term "active cooling". Active implies something more than diffusion with forced air.
Of course Intel will never admit to overclocking, the term active cooling is a euphemism for ??? Peltiers?, vapor wick devices"(heat tubes are one common name for these devices that use a sealed chamber with an evaporative fluid that when heated turns to gas(removing the latent heat of vaporization) which travels to the inside of a standard finned heat sink that condenses the fluid and the wick takes it back to the CPU(gravity can also take it back)). These heat tubes work well and are excellent until the temp gets so high that they cannot condense, at which point you have a CRAY type fire as the CPU is denied all cooling and becomes an expensive resistor.
