Intel Pentium 4 microprocessors with SSE3 technology also known as Prescott processors will come only in the first quarter next year, but already now a number of companies focused on coolers offer their new products designed to cool down the hot and highly anticipated Intel’s 90nm desktop chips.
The new Pentium 4 CPUs with SSE3 technology and improved NetBurst micro-architecture are made using 90nm fabrication process featuring Strained Silicon technology from the Santa Clara, California-based world’s Number One semiconductor producer. As a result of a considerably reworked micro-architecture as well as some issues with the manufacturing technology itself, Intel’s new processors are expected to consume and dissipate significantly more energy than their predecessors even despite of thinner manufacturing process. Typical power consumption of PGA478 Prescott processors will be over 100W, while for the higher-speed parts in LGA775 package the figure is heading towards roughly 120W. As a result of this serious problem of Intel Pentium 4 processor, Intel itself as well as companies concentrated on cooling solutions are going to revamp their existing products to efficiently cool-down code-named
Currently several companies specialized on CPU coolers, such as Nexus and CoolJag, are ready to supply their products designed for Intel Pentium 4 with SSE3 technology processors. The devices are specially designed to dissipate up to 103W of heat and cool-down Intel Prescott chips at 3.40GHz. The radiators of the coolers are made from copper and feature loads of thin fins to better dissipate the heat. Moreover, both products utilize high-speed fans for more efficient cooling.
Next year Intel promised to bring a new design of coolers with greater ability to dissipate power as well as improved cost-efficiency. As we revealed this September, Intel’s suggested heat-sink of the future will be round with semicircular fins and will implement bifurcated fins to enlarge the total area of the heat-sink. The solution will have a special copper core inside the aluminium heat-sink in order to provide the lowest possible thermal resistance for the core of Intel Prescott or Intel Tejas microprocessors. The diameter of this astonishing cooler will not be too large, only about 90mm, and will allow installation of very high-performance processors in relatively small cases. Intel will also reconsider the design of retention mechanism for the cooler for that reason.
First coolers for Intel Prescott CPUs from CoolJag are now available in
