<font color=purple>Laurie White, Toshiba Australia's notebook designer and product marketing manager, says the new Pentium 4-M chip has built-in thermal protection that ends up slowing the chip down using Intel's own SpeedStep technology, originally designed to reduce the clock speed of a processor once battery operation was detected in an effort to improve battery life. "What happens is that the processor has a lot of internal regulators inside it so, as soon as the processor heats up too much, it starts to shut itself down. It actually "SpeedSteps" itself down," White said. As a result, the 1.7GHz Pentium 4-M notebook "effective throughput is not 1.7GHz", he said. In order to maintain notebook temperatures within the tight 35-degree specifications of the Pentium 4-M, Toshiba engineers have had to add water-cooling plus a special "radiator jacket" to dissipate the heat without setting off the internal heat regulators. it.mycareer.com.au
