Hitachi Announces New Liquid-Cooling System

January 31, 2007 by Jeff Shepard

Hitachi, Ltd. announced that it will provide its newly developed Liquid-Cooling System for the latest model of AMD Opteron-based workstations by HP (Hewlett Packard). Hitachi developed the Liquid-Cooling System to significantly reduce heat and noise typically generated in high-performance workstation applications. The new system, which is claimed by the company to be superior to traditional air-cooling, with improved performance and reduced noise, will be used in the high-end HP xw9400 Workstation.

"We are assured that the HP xw9400 Workstation with Hitachi’s Liquid-Cooling System will provide end users with a quiet and comfortable environment. Working with HP is the tip of the iceberg, and we anticipate that other workstation manufacturers will follow suit," said Hideaki Gemma, General Manager, IT Thermal Solution Center for Hitachi, Ltd., Ubiquitous Platform Systems Division. "Hitachi is proud to work with HP to deliver the state-of-the art technology as market leaders and wishes to continue working closely with HP to develop even more attractive liquid-cooling products."

"HP is pleased to be the first workstation manufacturer in the United States to offer Hitachi’s Liquid-Cooling System in one of our most high-performance workstations," said Jeff Wood, Director of Product Marketing, HP Workstation Global Business Unit. "Hitachi’s proven Liquid-Cooling System will be a great benefit for demanding power users in digital content creation, scientific research, manufacturing, and oil and gas exploration applications."

Hitachi’s Liquid-Cooling System provides an acoustic improvement for idle and CPU max load states, as well as a lower pitch tone that blends easily into background noise. This is made possible by the removal of the CPU heat sink fans and by implementing a higher air flow (low speed) chassis fan for liquid-cooling, utilizing high heat transfer capacity of the liquid. The new system also provides reliable and safe countermeasures with high control of liquid permeation, degradation, and corrosion. which are Hitachi’s core competence.
