[NewScientist] Spinning heat sink could lead to faster computers

A redesigned heat exchanger could speed up your home computer, while reducing fan noise and energy use.

Air-cooled heat exchangers haven't changed much in 40 years, says Jeff Koplow, a researcher at Sandia National Laboratories. A disk absorbs heat from a computer's processor and transfers it to a row of attached metal fins. A fan stirs up the air around the heat sink. But only about five per cent of that energy provides a cooling effect. Why? A pesky layer of stagnant air clings to the fins, insulating them like a blanket. Spinning the fan faster helps, but it also makes computers intolerably noisy.
